This is a full build sheet for my Mark IV 4 bolt main big block Chevrolet V8. We
bored the cylinder bores out 0.030 and had the crankshaft machined 0.010 under so
we could reuse that and the block. The pistons and head combination bring the compression
up to nearly 10:1 so we will need to run 91 and maybe an octane booster when running
it harder.
