468 cid Pontiac engine on the dyno makes 558 horsepower 583 ft lbs of torque

Check out those headers turning blue!
This is a 468 cid Pontiac engine we built for Mike Matuszek and his '66 GTO. The engine is based off a 455 cid pontiac block. An Eagle crank and rod combo was used on the bottom end along with a set of KB forged pistons. A Tin Indian Performance custom ground Comp Cams hyd roller was also used with Comp Cams hyd roller lifters. The engine is topped off with Performer RPM cylinder heads and intake. We also used one of our custom 4150 1" spacers with the 950 cfm quick fuel carb. The combo pulled 11" of vac at 850 rpm! It made 558 hp @ 5400 and 583 ft lbs of torque @ 4500 rpm. ALL ON PUMP GAS!!! Watch those brand new Doug's Headers turn blue on the pull.
Tin Indian Performance thanks you for watching!

Fucking love the big block Pontiac sound

I like the way you can see the headers heat up. It really is a mean sounding engine. I could use an engine like this in my 2+2.. Great job with it! See you at Norwalk.

I got to save up , my 1972 455 H.O. is old school , L2394 TRW pistons , and get this a general kenetics cam shaft , 7f6 heads , it sounds great and runs like a beast but I would like to bring her into the 21st centery .
