Does anyone know how these cranks effect the compression ratio? I know that you need to use 302 pistons and 351 rods, but is a 10:1 piston going to give you 10:1 compression, or would you need to use a higher/lower ratio piston?(obviously heads would effect this, but lets pretend they don't)

When they say 10 to 1 that is with std capacity, heads.With std size chambers.Yes it will increase c/r..Pushing 725cc [5.8 ltr] into say 65cc would be higher than say?? 812cc [6.5ltr] into 65cc chamber..
