Hey guys. I have a GSR bough from a salvage yard because he had a stolen motor in it. I get to keep everything, but I must drill the block so it is not useable, by order of the city police. My question is, can I use a B18C block (P73 pistons) with the GSR head? Im fairly sure the blocks are the same, I know the pistons are higher compression. Can someone shed some light on this for me.
Thanks
Thanks
