"Shes got a lot of blow by, we better up the compression ratio!" Keep up the great work Rich!
hahaha, good post. Yes, another guy learning the hard way. If you don't meet the octane requirement 100% of the time you'll be sorry. And might STILL not know what happened. Call ME people before you start guessing your butt off like this guy did. The Edelbrocks and the right cam have MUCH more potential than this. Over 6000 sets done at my shop.
Reppin the MCM shirt at the dyno. That’s good for an extra 20 or so horsepower
I saw that, too. LMAO

An a Furze shirt at the end.
If you'd have told a feller back in '67 that one day you'd be able to lock out your GTO using a telephone, he'd think you're an absolute loonie.
I think a guy may be crazy for wanting to do it today, but perhaps some phones work more reliably than mine.
"we dont want a trailer queen" Yeah, no, don't put her in the trailer again Rich. She doesn't need another respray ;)
I'm running a 1972 455HO 30 over with old school TRW L2394 pistons , comp cams 294/570 , 7f6 heads , torker 1 with a holley 850 hp series carb. Been racing Pontiacs since the late 70s. Nice work , like seeing some Ponchos.👍👍🏁🏁
I was terrified when you set the new head on the guide pins and walked away without putting a bolt in, then when you set the other head on you see it lift. I thought for sure we were about to watch a brand new head hit the floor.
Wow Colin Furze t-shirt :o
Yesss!!!
I need to catch up on the videos of that GTO. 65-67 GTO is my dream car.
Getting ready to take the body off the frame of the '67 I use to play in when I was 4 this weekend. Your videos help inspire!
Good to see you not in the junkyard on this one. GTOs are one of my favorites. When I came back from VN I bought a near new 69. 4sp, no power brakes, no power steering, no horsepower draining anything.
Great information, I have been wondering about the elde.heads and you have filled in the blanks for me. Your GTO is perfect!! (with new rings)
Were they D port or round port he used??
@@Michael-qy1jz I'm guessing that since he just swapped heads, they were D ports. I'm also guessing they were not ported, just "plain" complete out of the box. Kaufman has virtually the same thing but supposedly more efficient....I'm really hoping, since I just ordered a set for my 65 GTO
@@justanobserver530 Yes, I ordered a set of Kauffman heads too in the first week of November so they gave me a timeline of the end of January, beginning of February to receive them. He said they are 10 weeks out.
Damn that's allot of blow by. Must have an issue with the rings.....
I'll never forget a Ford Wagon 200 ci inline 6 my mother bought from a mechanic in training. You'd drive it 15 miles and it'd be down another quart of oil. I think that car was single handedly responsible for the hole in the ozone.
@@johnpossum556 HAHA...I got a Tractor REALLY Cheap...from same thing...It was actually "Overhauled" but would actually spray oil out of the exhaust... He had Installed the Rings Up-Side-Down! All I did, was picked up a Gasket Set, and took the pistons out, IN FRAME, and flipped the rings...and had a nice usable tractor... After about 5hrs work!
@@johnpossum556 Nah. Back in the mid eighties, I bought a 1976 "Porsche" ( IE: high priced VW call girl) 914 2.0L from a used "sports car" lot....it ran great for the 1 1/2 mile test drive they allowed, but halfway home, it started blowing oil straight out of the crankcase, and into orbit. Six months, and a bank vault full of cash later, I traded it in at the first place stupid enough to take it. That was my first...and last, "Porsche" experience
Had a high mileage Mopar 340 back in the day; I put a lot of hard miles on it. Still ran well, but lot's of blowby. Took it apart finally. Had five broken rings.
@@timc9893 Funny I had a 1976 912E...Best German Car I ever owned...Had the Injected 2.0L Air Cooled 4cyl...It looked and drove like a 911, Accelerated and got MPG like a Beetle, and was reliable as a Timex... I am pretty sure your 914 and my 912E had the same engine... Your used 914 must have been shit kicked...
Rich! What you describe is called pre-ignition. Detonation is a secondary ignition even that occurs after the spark plugs fires. The result is 2 flame fronts that increases the rate of burn and spikes cylinder pressure before the optimal crank angle. Both are bad, pre ignition is generally worse and it's less controllable.
im sure all youtubers get all their advice from the comments section. you realize he is a mechanic right? moron
@@trillrifaxegrindor4411 I would agree, but I'm not wrong. Don't be a mook.
You have the best channel(s) on TH-cam! Tie down tip from 50yr trucking experience: 4 point tie down always! Love them goats!
Should have done a leak down test to check ring sealing before tearing the heads off.
That bump in compression will make it boil tires from a stop🏁👍
The big problem with Pontiacs and blow by is when the pressure starts building the rear oil pan seal starts pushing out. Eventually the pan seal will push out all the way and make one hell of a mess under the car, as soon as the oil gets to the headers via the torque converter all hell brakes loose. Make damn sure the flexplate cover is on the transmission.
Thank you for the comparison. Honestly I was expecting such big gains. Now I’m encouraged to by a sets of heads, lol. Nice project and beautiful car.
So was just going through some of the old vids. Had to LMAO at Rich's quote on the last one I was watching DG Hangout #22 It was him saying this "This is going to be a fast build compared to alot of the builds around here" referring to the C10 tow truck. And this was posted almost 2 years ago. ABSOLUTELY love your show guys. ❤️ From Vancouver Island gearhead 😎✌️🤙
Great video as usual, as plenty have said, time to see what the go is with the rings
Love seeing horsepower and torque boost ! Thanks 👍
94octane fine for up to 11:1 with conservative timing. Check your math. 72cc is 10.7 to 1. You raised the compression ratio 3 points.
Time to leak it down. Is that distributor locked out? Cranks like it has lot of timing on start up. Check your timing or put a curve kit in it.
Or just go to e85
@Russell Gerdes can't read that cancer. Learn to type
@Russell Gerdes why do you use uppercase letters Infront of every word?
@Russell Gerdes
Because E85 is ~115 octane and you can make much more power than any other pump gas you're going to get. More compression, more timing, more power, runs cooler. No downsides. $1.50/gallon race gas.
love the videos, always learn something
That is flat out a gorgeous color on the GOAT. Nice bump in power and torque with the head swap.
#totalsealrings Sure does seem to have a bit extra timing the way it kicks on the starter during cranking.
I thought the same
Try gearvendors. They offer overdrive attachments after the trans. Probably just have to get the drive shaft adjusted
That is the best year goat. Love the color, so good!
Love it....great choice of colour ...
Great video and my favorite car! I would love to have one someday!
Pretty car. I had a 67 LeMans convertible for a couple of years, but always wanted the GTO.
A number of years ago we messed with my buddies 383 Chevy and we put on Dart II cast iron heads with that swirl (efficient) shape. We found that it run well and made good power with a bunch less timing than it did with stock heads in fact it seemed happy over a lot wider range of timing.
Bad ass old hot rod man
Always loved the look of that car, color is awesome
Nice car, great video.
Glad to see you're a fellow Furze fan!
Great job and video 👍👍🇨🇱
Love that car nice upgrades
massive fan, flying into Canada in the next two weeks
lets build some thing to drive to whistler
Love the MCM T!
Love the shirt support for my other favorite youtubers.
I love the 65 Buick Riviera with what have to be the coolest operating cocoon hideaway headlights there have ever been, just the meanest thing apart from a 59 invicta coming at you down the street
What's all that smoke?? Hate to say this fellas (from a Pontiac guy) You've got a broken ring or two, preignition the cause! The ring static pressure will be zero, but the engine will (inexplicably) still develop near its full hp. The crankcase develops pressure at full throttle... and the dipstick pops up.
I've rebuilt five original (running) GTO engines with miles on them... all of them had the same problem, broken rings
Same problem with my old Holden after she overheated. Didn't get too hot but stuffed the rings. My fault for trusting the old 1960's idiot light. Turned out the globe was gone so the idiot (me) had no idea until she started running rough. Has an Autometer temp gauge fitted now. Awesome when a 10 cent globe costs you a full rebuild.
You need an overheating alarm.
Haven't you seen the ad ?
@@ThePaulv12 Yeah na, just need the gauge I have now.
Love this chanel!!!! Is a project car ever really done? No. I totally understand this and people say to me now what are you doing? It's a project car!! Love your work mate and keep up these great videos
Nice! Not having to pull the distributor👍.
Glad to see an update on the goat but yea that blow by is pretty severe. Heck just keep it below 4k RPM and you will be golden. Oh and dont let mr Bias ply and zip tie borrow it or it will hit mustard and ketchup fer chur.
Rich: Starts video saying project vehicles are never finished. Ends video saying several projects are nearly finished.
Me: Agrees with both statements.
Why did the engine sound funny turning over at startup on the dyno? Is it just wound up THAT tight, or was it just not getting the cranking amps or something? Awesome videos every time! Love your channel, love your shirt! Have you ever checked out Dangar Marine? He’s an excellent presenter like yourself. Be well, Paul (in Kingston).
New fav channel
Colin Furze AND a Mightycarmods shirt? Some good choices there.
Not a bad engine either, I've come back to domestic recently and have been building a Turbo 4l AMC Inline 6 for my AMC Eagle SX/4 4WD coupe. I've done what a lot of people don't like and kept the SX/4's height, technically dropping it a tad with new suspension, and have gone with trying to lower my center of gravity and making a great offroad/rallycross grassroots car. The 4l I6's aren't bad for power either...if you basically just replace the head entirely :|.
A fine collection of T-shirts in this video.
luv the vids... thx !!
As much as I get a stiffy from thinking about driving one of these, I know how much money I´d just dump into it to make it "the perfectionist way", so I´m just gonna stick with some shabby diesel truck.
Blow by is blow by per definition. Something is up.
Some good rings and an aftermarket cam and roller rockers that motor will probably gain another 75-100hp
id ditch it for a 460.did gm ever build a decent engine.?.
perfect! just opened a beer (German) and Deboss!
Smart man, no florid in those🤙🏼
Russell Gerdes Right, it’s kinda crazy. Straight tap water in most brews.
Sehr gute Wahl, Prost!
What you guys don't realize is I live in Germany. Even speak German.
Christopher Hall that’s amazing! I’m like from German stock, Austria. And live in Lancaster Pa in Amish Country and grew up in a church where they spoke high German when preaching. I heard Your beer purity laws come from the 12th century? There was a problem with grifters making shitti beer, making the peoples sick? I love history.
Nice shirt Rich! Mcm
You're right, Rich. No trailer queens. Awesome.
Can you run a leakdown test on each cylinder to determine which ring set's are worst?
Not really necessary considering he said he will tear it down to fix it.
You don't tear a engine down that much to only change one piston's rings
Pull it apart, measure the bores and ring gaps, re ring if possible.
thanks,no one wouldve ever figured that out.im sure all youtubers get all their advice from the comments section.
The rings lost tension. Don't waste time measuring since there's no other option but to replace.
trillrif axegrindor relax bud
Interesting you’d tell a diesel mech that....
After waiting months and months, I finally canceled the edelbrock head order I had in, speedmaster heads came in right away and flowed more cfm than the last edelbrock set we used.
I like them a little more rich underload.
I wish I had friends like that. My friends are only friends if I have plenty beer. Rebuilding an engine and lots of beer isn't a good combination.
'67 GTO is my dream car...
When the border opens back up bring her to Kalispell montana. Nice job 👍👍👍👍👍
Rockin the MCM tshirt.
That colour is stunning 😍, I hope that blow by issue was an easy fix.
@Russell Gerdes Easy as in once torn down its just a small problem not half the parts eating each other 🤷♂️
@Russell Gerdes They do this day in day out so its not particularly difficult for them but be a shame to lose the block if the pistons tore it up.
Digging the Furze shirt. Is that one of those 'Easter Egg' things the kids are talking about these days? Can we expect a CAT powered drift tank in the future? Ha!
Cheers!
Would love to hear the lovely noise that sort of engine make, but sadly, it'll have to remain a dream for now. :)
Love the Colin furz shirt
Too bad the rings aren't seating correctly but awesome video Rich!
Man you guys are all over the place with the videos. I kind of wish you would show one project at a time. It’s kind of hard to get into it when the videos jump around from project to project. Nice video either way though 👍👏
its free,watch it or dont
Happy friday guys :)
450 hp should be more then a little fun in that car! Nice!👍
If you come anywhere close to Knoxville, Tennessee, I'll have to get dad's 67 gto out and join you!!!! :-D or the 69 grand prix? or the 67 bonnie survivor? :) your pick!
Rich; when Canada opens the borders between Canada & the U.S. you need to visit Westen Champlin; he dropped a 12 valve Cummins into a 2015 Ford Mustang
Nice Rich is the master of suspense. lol
To beat the insurance companies. Pontiac rated all of there engines at 10 hp per 100 pounds. Hence, a 3700 pound car was rated at 370 hp.
377hp with 8:5.1 compression isn’t bad
That was a pretty sweet bump in the performance numbers
Sounds like ring drag on the hot start.
Man I wish you were in my neck of the woods i need a good mechanic that really k owns his shit like you. Everyone hear dont believe in fixing only replacing with new! I love old stuff and you dont always have to ye new if you actually no your shit. We need more like you in the world
ya keep a lil more of that air in the cylinders and it outta make a few more hp, sucking the excessive blowby back though the intake with the pcv system will lower the effective octane via oil contamination, a catch can/separator/check valve may be an option to dump it into the exhaust for short term reduction of stink/embarrassment/mess
Myself I would pop the pan slap some rings and rod bearings in with those new heads and been running the next day 🤷♂️
Rich... when you do a 68 - 69 [for yourself]... go with that same engine but with Butler Performance just monsterfying it [I believe they'll sell you one of their's off of the shelf if you can't find one]. Small operation but INSANELY on point. Check them out. Anyway.. love the end product with this one... maybe start with a Le Mans parts car and even a rat bastage 68 or 69... Slip off before or after power tour to either Arizona, Texas or Cali... get you one of those... Canada Needs them... they are beautiful muscle cars and with Butler machining things up to your delight... go trick flow heads and some juicy supercharger... ported madness.. aluminum this and that... tickity-boo. 700---> Horse Pucks! Yessir... sorry guess it's a dream car of mine since my brother took off for his honeymoon in a 68 back in 73 lmao I was like 11 years old and... woah man... kind of like a 67 427 monsterfied Silver vet his brother in law had.... He had a couple of shelby King of the roads from 67-68... but... that couple of years for GTO's... Get you some of that Rich. Just for you! lmao Get one of them to sponsor you for body panels and floor panels... wheel tubbers... for MEATY Beefy madness :-))
A vacuum pump sucking out of the crank case can help the ring seal better. It also could be the crank case of seal up too well.
Hope you installed a a good bit higher/longer duration cam on the engine rebuild to break up and overcome the higher compression ratio at start-up. Plus it makes for a real nice mid & high range boost in hp & torque. Looks good! 👍
no
Sounds like the starter is fighting too much timing, not compression.
Yup, better for detonation too.
Sweet ass motor!
Also, Rich.. If your ever in the southern maryland area and need a shop to wrench on it in, and a hand wrenchin.. I got ya bud..
My definition of detonation versus the charge burning it that the flame front in detonation MOVES faster than the speed of sound (~ 767 mph at STP). That is why you hear engine knock - the flame front moves with a sonic boom. The problem is that a flame front moving that fast is HOTTER than a burning flame front and thus things begin to melt.
Loving the ‘tubers shirts👍 furze for pm😂👍🇬🇧👍
I had a 69 Custom S back in the day. Pontiacs are true muscle cars.
I'd like to know where you got that lift table. ones ive seen only go about 3 feet high. And I'd reaaallly like to know where those wheel lift arm extensions for the 2 post lift came from.
Friend: my car has bluetooth radio and wireless headphones.
Deboss Garage: my car has bluetooth transmission.......
Not too bad on power, except you really need to replace those rings, a good project for when the snow comes. I would drive it like it is too for the summer, then pull it apart over the winter. I've spent all summer working on my 65 GTO rather than driving it much, the 455 likes to break transmissions. No shows or cruises this year anyway, and its not my 'race' car so its all good. Yours looks a lot better than mine does. Its very pretty. I'll have to go back and see what cam and heads you had on it.
Ya know, the 3 tube headers are not so great and you can tilt the trans to slip it past the headers. A 455 can turn 5500-6000 rpm even with stock rods if you have ARP bolts in them, so if you have forged rods 6k is no problem if you have enough airflow to feed it. No reason to stop at 5000, the torque isn't falling off so it makes more power above that.
Back in the 90s I had a stock rod/ARP bolt, 670 headed 455 in my old street strip Firebird that I shifted at 5800, the trans would shift when it hit 6000 and it ran mid 11s with a 3.42 gear, stock stall, 224/228/110 cam, and was pulling 3750lbs down the track. Had to put a 4.10 in it to slow it down to avoid putting a roll bar in it. That made it run 12.0s very consistently, but it was all done about 900ft into the run. 455s aren't very fond of deep gears, they like highway gears like 2.73-3.55. Ran it for over a decade, never even pulled the valve covers. The problem with deep gears is it moves the engine through the RPM range to fast and doesn't utilize the torque, deep gears are for small engines. Think of a 455 Pontiac being like a supercharged 350, it doesn't need much gear because it makes a lot of torque.
Those heads are on the 455 in my 65 GTO now with a mild hydraulic roller. Its my daily driver with 11.5:1 running E85 through a Qjet. Later today I am swapping the FiTech back on it because the Qjet is sorted and ready to go to my friend, who I built it for. Pontiacs and Qjets are kinda my thing, been building them for 35 years. I think its getting some 3.08 gears too, and the 12 bolt with 3.42 can go in the 68 LeMans with its low buck used E head 461. 3000rpm at 70mph just isn't gonna cut it without the OD of the 700R4. It did take a few years to break it.
It’s a good looking car your lucky to be near Cayuga
Your content is so diverse. I guess as a result of trying to get your channel off the ground. Anyway, this isn’t my favorite build but this episode was great. There has never been anything as exciting as the Audi. It was just so oddball and genuine and slightly foreign to us Americans. I know you feel the same way. You were more excited than any of us. It was a real roller coaster. Bring it back out and race the thing.
Working on it 😎
Just a thought, it might not be rings but instead be tapered cylinder walls, so you get good compression, but at BDC its blowing past the rings.
Don't forget you can run almost a full point of compression higher with aluminum heads on pump gas so you can go 11:1 on 93 no problem
i got 12.1,cleveland,351,with 302 heads,std,goes like a cut cat,in a bronco,on lpg..economical.still going after 14 yrs..commodores,[ pontiacs to you ],hate it.
Build a crankcase evac kit and see of that seals it up, electric smog pumps dont last running all the time but they are fairly cheap.
Crankcase catch can?
There is a catch can, but the pump pulls vacuum through the engine and helps rings seal. Results in a lot less blow by and oil leaks.
The rings lost tension, there's nothing to do but replace them. Everything else is just a band-aid.
Btw, I love Colin Furze. Dude is an absolute genius. I wish I had HALF of his fabrication skills!
