Didnt replace the bolts or resize them, just put them on the pistons. Worked out OK, I put 50,000 plus miles on the car with 4.11 gears and shifted at 6000 RPM. 1967 GTO with 400 and headers. Ran a best of 12.99 but usually 13.20s with slicks and open exhaust. 13.50s on street tires and thru the mufflers. Been setting in the garage for 26 years and just fired it up again a couple weeks ago.

you mean like this ? there's nothing "wrong" with it. 8 Pontiacs with SD421 motors as high qualifiers starting the NASCAR Firecracker 250 in 1962 at Daytona, dominating the race throughout. With forged GM rods going 160-165mph for nearly 2 hours straight wide open, to the boards. Build the same engine today using the same parts it's capable of the same thing. You didn't heat treat your rods ?
