[@JordieG8]

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.

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.

That is flat out a gorgeous color on the GOAT. Nice bump in power and torque with the head swap.

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 😎✌️🤙

Pretty car. I had a 67 LeMans convertible for a couple of years, but always wanted the GTO.

[@67polara]

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.

[@jessemoore9982]

That is the best year goat. Love the color, so good!

[@fntony4967]

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.

[@alexstromberg7696]

Or just go to e85

[@alexstromberg7696]

@Russell Gerdes can't read that cancer. Learn to type

[@alexstromberg7696]

@Russell Gerdes why do you use uppercase letters Infront of every word?

[@kylesonsalla7620]

@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.

[@fitzyholden1036]

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.

[@sshep7119]

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.

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 :|.

[@wdixon27]

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

[@TheFRiNgEguitars]

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

[@davidrusso4750]

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.

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.

[@tomtheplummer7322]

Crankcase catch can?

[@rcflanagan1597]

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.

[@231mac]

The rings lost tension, there's nothing to do but replace them. Everything else is just a band-aid.

[@donalddday7741]

in 1972 i got a 66 put high lift cam, 750 double pump holly, hooker headers everything else was stock and got 450 on the ground with 1972 pump gas ( 95/100 ) octane

[@ThePaulv12]

re the blowby, unless the motor has been majorly overheated it is unlikely the rings have lost tension. My bet would be if it has tapered rings in it, one or two of the top rings are in upside down but it's just a guess.
