Hey I just got a 95 cadillac fleetwood with 320K on it. Before I got it I already knew that I was going to go the ls route or see about rebuilding and upgrading the lt1 motor. With that said I'm leaning towards the lt4 heads w/lt4 intake, upgrade the cam, along with doing the 24x conversion. Would that be a more cost efficient way to go or is there a better way? It's a fleetwood so I'm not looking to out run vettes and z28s, just want some more power to get the boat rolling quicker and surprise a few folks with a mild sleeper fleetwood!

[@yeahididit9054]

Just LS swap it 😂 never heard that before 🙄 seriously though if you want to be like everyone else go ahead and do that. Much easier to work on and with than the LT1 but if you really do the homework and research the LT1 is where it’s at. I have a 1994 trans am lt1 that I’m putting in my lt1 Roadmaster It’s not gonna be cheaper to swap it to LS because you already have the LT1 on hand and all the parts there to make it operate correctly. There are numerous ways to overcome the opti junk some super cheap some not so much IF do the research and legwork 0411 swap is about $150 and the time to repin some plugs or swap to a coil on plug LS type ignition with junkyard parts for $300-400. If you had nothing to start with sure LS swap it but you have a 10.5 .1 compression 4 bolt main aluminum headed badass engine already that with just a cam upgrade and tuned properly will give you plenty of power. And the lt1 looks 10 times better than an ugly ass LS 😂

Send your heads and intake to Lloyd elliot to get them ported have him also get you a custom grind cam kit, his port work is damn near as good as those afr heads and will make power.
Next look up a torqhead or efi live ignition conversion kit, it does away with the opti spark all together and converts it to coil on plug like the LS 24x style. The gen 2 LT1 still is a great engine and can beat alot of LS cars but when the LS came out in 98 everybody moved on and forgot about these engines.

For those wondering the LT1 in the B-bodies are a little bit different than the ones that came in the C4's and F-bodies.
The B-body LT1s have two bolt mains and the cam profile isn't as aggressive, they have a different name too but I'll always call them LT1s.

[@yeahididit9054]

Hmmm that’s not exactly true my guy. The engine is called a lt1 if it’s an LT1 the only one that isn’t is the 4.3 “baby LT1” which looks just like a 5.7 lt1 but is gutless junk and sadly some people think they bought a “LT1” and get ripped off. Anyways the lt1 s in the B body’s and (D body Fleetwood caddy)had iron heads instead of aluminum like f body’s and vett. The camshaft was different to give it more torque for the much heavier cars and they were tuned far less aggressively that’s it. And as far a 4 bolt or 2 bolt officially I think the only lt1 that supposed to have them were the vets but in actuality you have about a 50/50 chance of dropping the oil pan and seeing 4 bolt mains imo based my experience

Another thing to add if you’re going to change to the MSD distributor there are two different versions of the opti spark 92 and 93 had its own so you would have to modify things to make it work, 94 to 97 You can use the MSD without modification because what happens is that the water pump will leak onto and or water will seep underneath the distributor cap and have nowhere to go so the moisture stays in there take the cap off drill a hole at the bottom somewhere. Attach a vacuum fitting to the distributor cap and run a hose somewhere else to make a outlet because the movement inside the distributor will allow it to get dried out but you have to have a place for the water to go these engines are awesome, granted they are a bit expensive to modify because they were only out for six years and only were in certain model cars in all honesty, not all LT1’s are the same B and F body were for the most part because of them having 2 bolt main’s the Corvette LT1 was its own because it was the only one with 4bolt main’s from the factory unless the engine was replaced by the dealer because all replacement engines were 4bolt’s, and the corvette had the most horsepower and torque until GM did a one up to that and made the LT4 in 1996

I had a '93 Formula 6 speed with the LT1. Strong running car for the time. Unfortunately i went through the scenario he mentioned. The water pump went bad, and it took the opti-spark out with it. This was early-mid '00s, and the MSD opti wasn't on the market yet. I had to get one from the dealership and it was like $450 .

[@bigadielldne7234]

LT5s r the gem tho especially in da 93”zr1

[@djtgrind]

Let me save yall some time. Don't buy that cheap optispark. If you can't afford the MSD, get that middle priced one that has all the oil seals. He speaking Facts

[@b.s.adventures9421]

Had a bunch of ex-cop cars with these back in early 2000s.
Super fun cars.
Sideways at every intersection.
Beat on them relentlessly.
Never an issue besides one of them having the leaking water pump, optispstk issue.
Not to hard to fix.

Crazy the difference in prices for part for lt1. Long tube headers 200$. Ls1 long tube headers 500$ lol.

They are good engine I got one in my 86 1500 with carb hei also an it work .

Out of all the series of the GRAND DADDY (SMALL BLOCK CHEVY), this was the bastard child. Its still better than 90% of the other stuff out there. GM learned, from this. The next one, they came with, is the COLDEST IN THE GAME. The LS

im looking to mabye build a 302 sbc using a lt1 an a l99 or the baby lt1 as some call it you use the crank an connecting rods out of the 4.3 v8 in the 5.7 but you ovisley keep the 5.7 pistons.

[@mattpierce7688]

May optispark was tuff to diag too. I had a 94 firebird (pre 98) so old ci.puter kept reading hi resolutions. Car would start, run, stall after about 10 mins. Not start again til next day. Opti spark was the issue.

[@mattpierce7688]

Sorry about the typo. *computer

[@mikemossa9640]

I have a 94 Z28 with the LT1 T56 combo. Not a bad ride but you were spot on about her problems and flaws . That and the interior was shet.

[@TheGeneralMotorsGeezer-we3dg]

Opisparks also need a passive ventilation setup.

[@kanamekiyru]

You only need an aftermarket opti for anything before 96

The under dog! My favorite engine!

[@user-pe3mp6nx5e]

Thank you guru!!

[@quintonmeskimen]

my stock 1996 lt1 never had any issues. granted it only has 13k original miles

[@ajyoungsr3238]

I put. A chevy manifold on it and used a carburetor and old skool style distributor. Yeee. Sliden

[@larrymontgomery4902]

Msd has been top dog of ignition parts and systems FOR EVER

[@nitomeanboyGBODY]

Boy I hated changing those distributors.. but long live the baby lt1 (4.3s) and true lt1 🙌🏼🖕🏼

[@pierrebell1713]

For a second I thought it was Mos Def with a southern accent

[@KidJaeProductions]

Might be something to think about for a 1994 to 1996 Impala SS 🤔

[@joeethereal2968]

It's really a Mitsubishi Electronic Hall-Effect Trigger Ignition
