- FULL DYNO RESULTS. NITROUS, CAM, ROCKERS & INTAKE. Discounting the limited LT4, is the LT1 the most powerful factory small block ever produced? Check out this test on the OTHER small block. We run a number of different modifications on the LT1-but forgot the valve springs!! Check out the gains offered by Zex nitrous, 1.6 roller rockers, a mild Comp ca and an Accel Super Ram.

Please keep this LT-1 stuff up. Nobody showcases these amazing motors
Got a lt1 Camaro still strong
Right its due to the fact that pride gets in the way instead of the 2jz swap on my bmw i am going to maybe due this om my bmw. Lt1 is iron block as well and pushes good enough to do the job.
@Jack Russelle Lewis nobody asked👍🏼
@Jack Russelle Lewis not really lol ls block can’t take nearly as much boost as the iron block in the lt1 iron over aluminum any day
I have 1993 trans am 6sp 4.11s it's a torque monster
The LT1 F-bodies ruled the mid-‘90s. 300hp and 6-speed from the factory was a game changer in 1993-97
Owned 3 of them use to race on weekends outran a lot of mustangs
And the power output capabilities nowadays are crazy
I just got a 94 z28 a couple months ago. It’s an auto, but even then, 0-60 is in the 5’s. I need to put some street slicks on it for more traction cause even with c4 wheels, I’m spinning from the dig through 30-40ish mph
The LT1 Fbodies didn't make 300hp that was the corvette. The Fbodies had either 275hp or 285hp. The 96-97 SS had 305 I believe but those are pretty rare! Then in 97 SLP slapped the LT4 is about 500 97 SS camaros and they were rated from the factory at 330 but they were more like 350-360 hp! The 97SS LT4 was actually a tick or two faster than the LS1 C5 in 97.
@@eatmysalt291 be careful! The 7 1/2 inch 10 blot rear-end is the absolute weakpiont of those cars! Too much traction will destroy the rear-end! And if you are spinning through 30mph with C4 wheels that thing is FAR from stock!! I had a modified 95Z28 did mid 13s in the quarter and if I wasn't power braking then it flat WOULDN'T spin off the line it would just hook and book!! You probably have VERY old tires on because it shouldn't be spinning the tires like that!!
Back in the early 2000s I had a mint white 1997 WS6 that had this engine. I put on a set of LT-4 heads and the red LT-4 intake off a grand sport Corvette. Comp 306 cam, dual 58mm throttle body, MSD 6AL, and jet hot long tubes, x-pipe, bullet mufflers and dumps right before the rear axle. It made 446 whp and was without doubt the best sounding car I've ever owned. I wish I knew where that car is today. I sold it back in 2008 to a woman in Missouri. She bought it for her husband who was in Iraq at the time. I cant imagine how thrilled he was when he got home and saw it in his garage.
I worked at Flint V8 engine plant where these engines were made. The corvettes have a Forged Crankshaft, 4 bolt mains, and a different casting on the heads. When the engines are test fired(without a car) on a stand, they are run on Natural Gas, no gasoline in the plant. When they get in a hurry they fire them without exhaust hooked up, very loud inside a building. Then they get loaded onto a rail car and shipped to Bowling Green. Sometimes when there is a deficiency, a few get loaded onto an Airplane across the street, maybe 20 of them, and flown to a plant to keep the line running.
please do more LT1 stuff , and would love to see it in action not just pics .
Agree
Yes, more LT1
More LT1!!!!
I just bought a 1993 corvette.. 6 speed.. in 2023 and it still get a huge smile. This is FUN! I CANT WAIT to slapp on some bolt one performance let alone do some machine work😊
Hell yeah. I have a 93 camaro, it came with some bolt ons. Tons of fun and good power for a 30 year old car!
Corvette LT1s typically came with 4-bolt mains, while the F-body motors have 2-bolt mains
I did not know that. Thank you for the fun fact I'm almost embarrassed that I didn't.
I’d rather hav the 2 bolt anyway an hav it splayed in to 4bolt
And the heads are different. Tried to use Camaro lt1 in vette. Exhaust was different
When he said forgotten warrior a tear fell🤣
Lol SALUTE
Back in the day I had a Lloyd Elliott LT1 cam and ported heads. Made good power. I had that LT1 Z28 for 11 years. I loved that car!
Iv got a 95 lt1 camaro has motor trubull but was told it had some work done on it not sure yet on what the cars ganna do just got it few days ago
Lloyd Elliot helped me put a lot of hurt feelings towards the LS crowd back in the day
Lt1’s are pretty quick, look at the “grub worm” !!
I'm familiar
Yeah, Grubb Worm recently ran a 7.28 @ 196 mph.....small tire, stick...flying👍
Ya grub worm is kinda my hero. Run what you got lol. An lt1 with upgraded engine management and boost is a pretty straightforward way to have fun
Jonathan has it together with the Grubbworm! Block filled, methanol, destroked and a solid roller, ported LT4 Heads and intake, etc etc. It makes over 1400 rear wheel, not typical but they car has helped breathe new life into the LTX!
One thing I absolutely loved about the LT1 engine was the sound on the 1996-97 Camaro SS. That factory exhaust that came on that car made it sound so aggressive and heavy with a deep hollow growl. It sounded better than the 80 series Flowmaster that was specifically designed that 4th gen Camaro/Trans Am, but that LT1 engine sounded way better than the LS1 engine. If I had a 3rd or 4th gen Camaro, I would keep the LT1 engine in the 4th gen, and drop an LT1 or LT4 in the 3rd gen.
Back in the early ‘90s the LT1 was a huge deal. 300hp, a 6-speed tranny and 3.42 gears from the factory was just amazing back then. My old ‘94 Z28 just pulled up top forever lol. Loved that car.

My 96 LT4 put down 324 with 50k at the dyno ran a 12.8 on street tires. It out runs my brothers 98 ls1 vette. Love the LT they don't get the love they should.
Love it. I have a stroker LT1 on Nitrous - it made 600rwhp on 175hp shot in Calgary Alberta's elevation. It's a fun car (1996 TA WS6) and people are shocked to find out it has an LT1 still
The, lt1 is the best motor to ever exist for an iron block small block 350 it came on the corvette as well and of course the camero and am considering doing it as a, swap on my m3 e36, the ls1 over-rated and the 2jz so i think i know whats going under my hood, now bmw engines, cost way to, much to maintain.
Also, the LT1 heads and intake can use some mild porting with a Dremel. Just cleaning up the castings and smoothing out the the runner angles made a difference up in the higher RPMs.
A Dremel??!!?? Who are you kidding? You cannot port heads and intakes with a Dremel and do a good job ... come back to reality, dummy.
The Lt1 is a Monster! I had a 96 SS Clone Ported Heads 1.6RR Long Tube Headers and 3 inch Exhaust And some weight reduction. Never lost a Race with that Car
Love this video!!! Thank you for posting it. If you have anything else on the LT1-LT4 PLEASE post it. It's nearly impossible to find any videos on the LT1-LT4. And most of the ones I can find aren't worth watching.
I'm running 292 Comp Cam xfi , AFR heads, you can see my videos @604merlinIII
I have a LT1 in my 93 C4. 383, 24x reluctor based ignition, holley hp ecu, true sequential fuel injection,07-503-8 camshaft, Comp Cams 224 230, forged h beam rods, wiseco forged pistons, AFR heads, 11.5 - 1 comp, etc. On pump gas (93) is made 425whp, 434 wftlb with 365 wftlb from 2k to 6.5k. I love it. Very snappy throttle response. Built for track, autoX, and street.
Nice ride. What color and wheels?
My plans for my black coupe 93
quarantine king of content, so far XD idk who would compare atm with how much content is uploaded. Plus the format of the videos is just utterly awesome, short, yet jammed pack with gobs of good information.
(as long as there are engine noises we be happy XD)
I love my lt1. Got a small cam , 1.6 rockers , long tubes , and a tune. Been a great car for 14 years
When you put those 1.6 rockers, did you have to change your knock sensor?
Thanks for doing this!!!! I'd love if you did more LT1 stuff. Keep up the great work!
Everything little thing you do, Richard I’m amaaaaaazed by youuuuuuuuu
I needed this. I love my LT1 (95 Impala SS). I don't want to swap it I just want to hang with the LS cars and the SRT-8s
Same here bro. What you end up doing?
I have a 95 impala lt1 in my 92 camaro loved it because I bought it from a guy who built it for drag racing it always had problems pretty sure it was wiring though
Thank you Richard for the video and I'm keeping my LT1 inside my 1996 Chevrolet Impala ss car and also by me keeping this original engine inside my car it also keeps the value more profitable for my classic car.
I agree I would never LS my 1996 Impala . I did do long tube headers. CC503 1.6 roller rockers. Behive springs. Next the transmission.
I'm still playing with gen 2 engines, they really are overlooked and underappreciated by the masses.
I would love to see some big bang stuff done with one! Keep up the phenomenal work Richard.
So happy to see this. I've got an lt1 and t56 from a '95 TA I've been wanting to swap into something. Never knew what I could expect out of it with just a cam and springs. I'm planning a slightly bigger cam than what you ran here, but good to see the heads can support it well enough.
Richard you are my hero you do all the best tests most thorough (sort of lol) love all your tests and your daily updates keep up the good work brother...
Thanks, will do!
@@richardholdener1727
I'd like to see some boosted LT1 stuff of this generation like the alum head version or iron version so I could compare to your boosted TPI video.
Thank you for doing stuff with the LT1, please keep going. springs and aftermarket heads would be really interesting! Thanks again!
all 3 of my cars have lt1's so i really appreciated seeing this. tons of good info. great job!
I’d like to see a test with aftermarket valve springs and heads
LT1 has good heads, they just need to be ported
Elliot'sportworks, Lloyd does awesome work with LTX engines!!
Cyanide UO they're are limited aftermarket head choices specific to the LT1, Dart Pro1, Trick Flow (TFS) has a couple of different castings, Brodix I think at one point offered a head for it, Edelbrock has heads but they're nearly pointless to bolt on although with porting they may be ok and then there's AFR who has the most choices and are CNC ported. Out of the box they're hard to beat. Not to mention if you can get your hands on a set there's also the LT4 Heads but you need the matching intake because the intake runners are raised .100 All of the aftermarket choices aside from AFR are just ok out of the box, some have different chamber volumes and the TFS 185X (which I run) has a 21* valve angle. In ported form they're great heads, even the stock heads ported by the right guy (Lloyd) are amazing but have limited deck thickness and won't flow as much on the exhaust side as a ported aftermarket casting. So if you're willing to spend the extra money on an aftermarket head like I did and have it Ported you end up with a phenomenal set of heads for the LT1 but for the price of buying an aftermarket head ready to bolt on you can have factory heads ported that will perform way better than the unported aftermarket heads. If your interested in the LT1 I suggest you check out Elliot'sportworks!
@@viciousrap700 All very true. I have a 96 Impala with the LT4 heads and intake that were heavily ported. That along with some boring, stroking, a little Procharger, and basically replacing almost everything other than the actual block, it's making over 700 at the wheels. The power comes on really quick, I use a 2200 rpm stall Vigilante torque converter with a beefed up 4L60 and 383's and the bastard moves pretty nicely.
What distributor do you recommend
Anybody who doubts the lt1 look up the grub worm by tick performance you are the man richard
Awesome information !
Thank you very much for all of your time and effort, you are enriching our lives and increasing our driving fun factor many times over !
@ 13:26 personally i used a GMPP GM performance LT1 4bbl conversion intake, which fixes can accommodate a classic HEI distributor, which i did on my 87 raptor-liner'd firebird. this fixes the both the common optispark issue you mention and also remedies the restrictive TPI type EFI intake. so with this GMPP 4bbl conversion intake you can have more CFM's , and delete the optispark & run a classic distributor. its powerful like the LT1 but simple and reliable like a carbed SBC with HEI ignition. best of all 3 worlds.
It’s so cool all the different test u do! Thanks for all the info! Best channel on TH-cam!!
Thank you!
Great job as always ! Love your tests and passion to make power...on everything !
Please do some more LT1 OR LT4 stuff :)
Corvette lt1 4maun bolt camaro 2 main bolt. Nice to see someone bring up the lt1 since they are solid engines with good power and have been forgotten by a few people
The low end torque on these LT-1's are amazing.
we need more upgrades on this generation LT-1, I love my LT-1 6spd corvette, but would like more, much more!
U can do a 383 or 396 stroker LT4 hotcam kits. They sound amazing
Boost
@@eastoakland-S65feen hot cam is way too small for a383
It would be interesting to do popular cam choises like cc503, gm846, gm847, etc. Then do stock heads (with valve springs haha) maybe see the difference in power also between 1.6 & 1.7 rockers, then do ported heads with different combination of i&e valves. Then stroker 383, nitrous, and finish with turbo. Maybe that's a lot of work haha. Thank you for the content. It is always interesting watching these tests.
Very good suggestion
Yep!
LT4 heads come with .100 raised intake ports, also 2.00 int valves compared to 1.94 on the LT1..The LT4 Manifold is also has raised ports to accommodate the taller ports..The LT1 and LT4 cams are very similar except the LT4 comes with 1.6 roller rockers that gives it an additional .30 valve lift plus a little less valve train friction. The LT4 came with 10:8:1 compression as to 10:5:1 for the LT1, this was achieved by having only 2 valve reliefs on the pistons as to 4 on the LT1. Also the LT4 came with larger #28 injectors.the LT1 came with #24 injectors.These were the major differences between the two for the performance differences ..There were other improvements as well.The LT4 had 4 bolt mains while the LT1 had 2 bolt mains.The LT4 also had a less sensitive knock sensor allowing for more timing to remain in the tune during a knock detection. The LT4 knock sensor module inside the ECU is a good mod to add to your modded LT1 engine.Your tuner will thank you...lol
Woot woot!! Finally an LTX!!! So much more aftermarket we can do with this, Richard!!! I know that these are old tests and you don't have this engine anymore but man I wish you did. I'd just like for people to see what these things can do with a Elliot'sportworks ported set of heads and intake and one of Lloyd's cam packages. This engine needed springs so bad that it wasn't even a fair test but honestly these LT1's like way way more camshaft than the 264 cam. Commonly one of the smaller yet popular cams for the LT1 Is the Comp 503 cam and that's a small cam! They like CAM TIMING lol!!
The LT1 community would love to see you attack this with aftermarket heads and a bigger cam. A big bang version wouldn't hurt either lol.
Say, Trickflow heads, Tick Performance cam, Edelbrock "LT4" intake. Hell, a 12.5:1 383 short block would be nice to see too. These engines are pretty hated on.
@MajorLeague the LT style intake was the TPIS Miniram
*cam motion cam *tick performance cam*comp cam * and the gmpp cam*
How about the popular AI heads/cam or Lloyd Elliot packages. There are big gains to be had up top.
@@wjrneo2 I had an lt1 with the full LE3 setup, to include all his recommended mods. That car was incredibly fun.
My LT1 is punched to 383 stroker, comp cam, ported heads, bigger valves, hooker long tubes and catless off road y pipe. I bet it's faster than my 2018 Camaro ss.
I loved the LT1 in my 87 RX7 turbo. Believe it or not, if you spin a stock LT1 to near 7k enough times, they protest.
laughs in opti
Gee, ya think? Honda's do too! Been thar dunnit! Lol.

I'm the original owner of a 94 Trans Am. I have 337.000 miles on my stock engine, never been touched, even the timing chain is original. Still runs like new, and still quick. Uses no oil either.
What kind of oil do you use?
Castrol GTX.
If only we had this information back then we would have taken different routes. There wasn’t much info and were scared to explore new things if it did not pay off so we went with what we knew was solid info. I remember when they developed Dyno software for the computer to estimate Hp and Tq ratings. But that was expensive too. Great video.
Would love to see more about the LT1 mods you can do. Thanks for this. Subscribed.
I’ve BEEN WAITING for the video!!! 🍿🍿😎
Now there's a new LT1 everyone is talking about.
I have owned 2 z28 LT-1 6 speeds. I still have one. Thanks for putting this up! I am impressed at the big torque boost from the Accel Super Ram ! I would love to see some "big bang" on one! Peace
I love your channel man. You work fast.
Finally the best sbc ever!
I loved my LT1 Buick Roadmaster S/W. It responded well to small mods, but I also had valve float issues with the stock cam. Of course I had over 200k miles on her.
Also Great Channel you have. A ton of info and your Live feed is awesome !
Thanks! Feel free to keep the LT1 videos coming!!🌟✌
Yes! I own a '96 Caprice Classic ppv with a 5.7 Lt1.
Yes, definitely more LT1! This engine was in my first “fast” car. It was a 95 Camaro and I freaking loved it!
Cool, my first "fast" car was a 96 TA 6 speed, allegedly with an LT4 engine. She was fun, more of a stunt car than a drag race car as it would always spin crazy bad. Gears 1-3 were near uncontrollable and that's the way I like it.
Agreed to testing more LT1s. You're videos kick ass man! I've been periodically watching but this one made me subscribe.
welcome aboard
Loved the test and thank you for speaking the truth of the LT1 my 95 camaro is plenty happy with her LT1 but now after seeing this I feel I need to get a super ram intake.
Yo brother! You da man! Trying to talk my father-in-law to come off his 40,000 mile c4. This is right up my alley.
I had an lt1 back in the day when I was in high school it was in a firebird formula 1994 model. It really had pretty good power for the day and used it well. In stock form other than k and n air filter and flow master exhaust it was running in the high 13s at the drag strip. That was an auto car with a 4l60e and 2:73 gears. The reliability was not great as in it did not always perform well it often would have a problem but when it worked I was one of the fastest high school kids around.
I PICKED UP A 95 FORMULA FIREBIRD , HAS COLD AIR INTAKE , PERFORMANCE EXHAUST RAN 13.7 IN THE 1/4. PUT ON A 100 SHOT NITROUS , GOT DOWN TO 12.5 IN THE 1/4. WENT UP TO A 125 SHOT , THEN TRANSMISSION STARTED SLIPPING FROM 2ND TO 3RD ! SHOULD STAYED AT 100 NITROUS !
Your fathers car sounds nice.
Have a lt1 in my 72 nova fully built forged pistons, comp camp, harden rods, roller rockers, port match intake to heads also went with the conversion intake so distributor is in back with electronic water pump and just added a holly sniper Efi. Im very impressed with it!
Love your videos keep them coming.
The good old LT1 can get down into the low 7s now with a T-56 manual gearbox. 👍
Grubworm ftw!

@@juniorlemke5484 my t56 in my Camaro is faceplated. Works great like that.
Yes that is crazy how fast they are with that combo
LOL
Just swapped for a complete lt1 drivetrain yesterday. Talk about good timing 👍
claburn123 I had to put a 96 z28 complete drive train in my 93 z28
I used to have an M6 97 Z28 Camaro Anniversary edition. They came with the same interior as the LS1 cars but still had the LT1. The broad flat torque curve made it so much fun to drive.
Great content glad i found this channel
The 1992 ~ 1997 LT 1 engine was essentially the same except for slightly different intake and exhaust duration. Also valve lift was a little different. They were used in Y body, F body and B body. Some engines had cast iron head vs. aluminum. The Corvettes had 4 bolt main caps. Some say the iron heads flowed better due to a later production date. In 94 they went to Sequential Fuel Injection from batch fire injection. The early cams drove the optispark by a spline. The later units were driven by a .620" cam pin. The later production optisparks were better vented for condensation.
I have a Iron headed LT1 in a 1951 Bel Air things runs good and I'd love to see a big bang with this Motor.
i put one with iron heads into my 87 firebird a few years ago. i love that engine after doing the GMPerformance conversion 4barrel intake
Just bought my parents 97 z28 with 56,000 miles.I can't wait to get it going.These engines deserve more credit. Bowties for life 💯
Love these. Would love to see the same engine with a modern bigger cam. Then with better heads/springs, then turbos! Thanks for all the testing you do!
More to come!
When I installed my 1.6 roller rockers, I also installed new valve seals and stronger springs. Then I raised the rev limiter and shift points by 200 RPM. I also installed an LT4 Knock Module. Pulled much better until the OptiCrap started mis-firing at high PRM after 20K miles. New heads and cam are next. Want to see more LT1/LT4 stuff
Nice! Please do a test with ZR1's LT5 stuff. That engine deserves more attention.
Please keep up the good work with the lt1 i have one in a 96 ss/z28/slp and love it
This video was great. More lt1 content please.
Raced a lot of lt1 combos over the yrs. Very under rated.
An electric water pump helps . a little more cam than the one in the test with better springs will also make good gains.
at the drag strip I would remove the thermpstat, run the pump contiuously to maintain a lower temp which made my Impala very consistant.
Only thing I did not like was when the water pump went out, it took out the Opti Spark distributor with it and was very costly. Otherwise coupled with that awsome 6 speed, made a boring trip to work an exciting one.
I had on for 11 years. An aftermarket company started making a bolt on shield for that problem. It basically let antifreeze/water go around the optispark. It was cheap insurance.
Easy fix. You can tap a rubber house with a small metal brass fitting into the weep hole and routed it away from the opti. Just $15 dollars and no more headache!
Same thing happened to my ‘96 Fleetwood. Never ran right again after that.
Same thing my 96 caprice was amazing till that wp went out n took the optispark with it. First time i fixed it everything went perfect. Ran amazing all summer. Come winter. Engine wouldn't get warm enough to run the heat. Vented 100x couldn't get it sorted. Gave the car away lol
A little silicone around the opti cap fixes that problem for good!
It was explained to me by many people that were better informed than I, that the LT1 in the Camaro/Firebird twins had a 2 bolt mains, and the LT1 in the 'Vette had a four bolt mains. That difference allowed GM to tune the 'Vette LT1 for more power; from 275HP to 300HP for the Vette, and yes, there really was a difference.
the mains had nothing to do with the power output
Man great video showcasing the old 2 nd gen LT1, this reminds so much of highschool days when the Fbirds and Camaros and SS impalas were hot and it’s reminiscent of my college days working at the Pontiac dealership as a porter in late 90’s, I once had the pleasure of handing a rare brand new 97’ Fire hawk . I do remember reading and noticing when the LS1 was introduced in the F bodies in 98’ the LT1s from 96’/97’ were said to seemingly have a slight bit more “seat of the pants “ feel and more grunt off the line! But this good infor to know and play around with, I’ve been eyeballing an old LT1 94’ firebird to buy since everyone is ignoring it , and I guess understandably so in this world of wonderful rt hemi’s , Scat packs hellcats , current GM muscle and ford muscle cars/truck. Anyhow this in for is great work much appreciated!👍🏽👍🏽🔥🔥
Very cool to see the Gen II SBC LT1 get some attention!! Had one many years ago comp cc305 cam, springs, shorties, LT4 knock module, meziere elec H20 pump etc etc
If possible I think alot of us would love to see this series continue. Definitely upgraded springs would be great to see
Let's see the 4.3 as well! I'd love to see tests on all of the odd ball small displacement v8s. How about a 307 or 301? Maybe do some v6s as well, 3.8 ford and buick, 3.9 dodge or maybe even a slant 6? Let's see some weird and unloved engines!
I am 68 and am the original owner on a 57k mile '97 Firebird Formula WS6, non-T top with the LT1 and 6 speed. I just subscribed and am very excited about following along on ANY future videos on the LT1! My "other" driver car is my '70 Boss 302 Mustang that I have owned for 46 years...... p.s. nearly everyone is telling me to pull the "boat anchor" LT1 out and put an LS in it to go fast. Thanks for inspiring HOPE!
My 94 Caddilac Fleetwood 22ft limo came with TheLT1 I loved drifting that limo in the Rain🧐
I've got the baby LT1 in my '94 Caprice that has gone through 3 water pumps, but still running the original optispark. Whoever thought of putting that engine in a car this big and heavy needs to be kicked in the junk.
I still remember the first time a guy told me he had a 4.3L V8 in his Caprice. I thought he was smoking something.
I currently own one 4.3 LT1, two 5.7 LT1's, and have driven at least a dozen or more LT1 equipped vehicles over the years. Believe it or not, some of the 4.3's are nearly as powerful as the 5.7's. I've also driven some 5.7 LT1's that were just dogs with no obvious mechanical issues. Whenever I purchase an LT1 car i always test drive it first o make sure it's not a pooch.
Swap gear. The 265 has poor low end torque.
GM also put the LT1 in some Firebirds, Caprices and Impalas, and the last couple years of Buick Roadmasters.
Russell Loyd welded up a Schweitzer turbo in a 9C1 Caprice. The shits and grins in a beat up old boosted black cop car were epic.
These engines respond well to boost. It was perfect with the factory 3.08 gear.
B body LT1 had cast head an different top end was built for more torque an less horse for the heavier b bodys
The B Body LT1 is basically the Vortec 350 used in the 96 and newer trucks with a better intake. Obviously the LT1 is reverse coolant flow, cam driven water pump, optispark and the Vortec is a Gen 1 but that's not how I mean. The iron LT1 cylinder head is very close to the specs of the Vortec heads and the cam used in the B body is actually the cam they used in the Vortec 305 and 350 lol. I have owned both... perform pretty similar.
@@davecarakasavage919 That's not an LT1. Didn't come out until the '92 Corvette.
@@davecarakasavage919 the LT1 wasn't put in a firebird/camaro until 1993. So if you have one in a 91 it wasn't factory.

Daniel Lawson have you had to change the optispark in your 96? I pulled my LT1 and trans from a 96 Buick RM. wondering if I should change it or just take my chances and install the motor with the stock one.

@@richardholdener1727 that would be amazing to see. Iv had the privilege of working on one .
They respond well to headers and then porting of the plenum, injector housings , and heads. There are also cam tricks. You can re time them or regrind them. After that it's displacement with either changing the cylinder liners and pistons or stroking. You can also add spray, or turbos, and some owners have run a super charger like a vortech. Of course a larger throttle body can be used. Kim Baker of Baker Racing found that the smaller throttle body he had to run by sanctioning body limited H.P. but made more torque. Let's not forget tuning which will require burning a new chip to take advantage of the mods. Back in the day it was Lingenfelter , Callaway, Doug Rippie , Auto Masters. Today it's guys like Marc Haibeck, Corey Henderson building ZR1'S with awesome LT5's . My 91 has all the mods on a stock block 350 cubic inch displacement including the light weight Fidanza flywheel producing 528 H.P. at the crank . It was just short of 450 H.P. on a chassis Dyno.
Faster proms Corvette is 600ish to the tires that engine was state of the art for the time.
Cam shootout!!!! Tick cam. Comp cam . Cam motion cam and gmpp cam !!! And the lt1 intake and lt4 intake !!! Dude I think thatd be awesome content !!!
yessss
100% agree more LT1 testing in those areas as well as valve train upgrades!!!
Hi from the U.K. great channel great engine 👍🏻
awesome, just got a roller 89 firebird and bought a 96 z28 lt1/t56. Cant wait to start working on it!
I'd definitely be interested to see what happens with better springs. Didn't really feel like a fair fight at the top end at all.
Seeing this in lt4 form with lt4 cam and ported heads would be cool see the real power difference from factory
Loved it, please do more LT1 testing. Would have loved to see where the limits of the stock heads are.
That super ram was a monster on the street. You were the king of the stop lights on Telegraph Rd. on a Friday night. You may not be familiar with that one, Richard. It's in America just outside of Detroit, Michigan. Yes... that was a jab at California.
Hot Rodding originated in California-Detroit followed
Thats good power for such a mild cam. With the reverse cooling set up the LT1 has, you should be able to run a ton of compression or boost. Im really interested to see more on these motors.
Replaced my opti-spark so many times that I could do it in only 4.5 hours! Opti-spark was the reason I junked my Caprice.
I drove my LT1 car for about 6 years... Never a single issue with the optispark, even when the water pump failed. Had multiple issues with the Ignition Control Module though.
@@mxguy2438 He just repeating what he read on a forum.
@@blackericdenice im still on my stock opti! 94 caprice flp long tubes, 2800 stall, 373gears with eaton posi, 2 stages NX using a sx2 fogger. i got a wally and a track championship... you can get coilpacks 24x
@@mxguy2438 Ive had my formula for 20 years. No optispark problems. i think most "optispark failures" are caused by ignition module related issues. I replaced a few ignition modules before i figured out the ignition module's connectors wires were bad.
I just got a '96 LT4 (6-Speed) Corvette. Revs higher & pulls much stronger than the LT1s I've had. A lot more different parts than most people think.
My first car was a 95 camaro z28 lt1 t56.. was a ton of fun and reliable as could be with a 17yr old behind the wheel!!
