Old combo i had laying around 3.60 stroke 5.7 chevy rods 12.5 cleveland pistons 740 lift roller . Never had it on dyno . Ran 10.40s 130 4 years ago in 2800 pound mustang only change useing a set of gapp and roush high port heads. Going in 65 falcon im building.
would like bigger bore for these old prostock heads to breath. thouht about furnace brazing a block with big sleves old school .
only the 82/84 F350 block (siamese cylinder bores, often refered to as the nascar block) will take a decent over bore. tru blu is right, .030" is about it for stock block and performance use. save money in the long run and go aftermarket. cheers
