Mike Matuszek came to use wanting to do a rebuild on his 468 cid Pontiac engine that he was using in his ’66 GTO. He just did NOT feel it was making the power that is should be making.
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.
