I am new to stock eliminator racing and i am looking at getting a motor for my 1984 cutlass. After looking at the blueprints on NHRA the only difference between the Olds 305 and the Chevy 305 are the pistons...So my question is i found a 305 sbc for sale that runs good but it has flat top pistons and according to the olds 305 it had dish pistons is it legal to run the flat top pistons or do i need to find another motor??
