Hi, thanks for your reply unfortunately that crank is a later 8 bolt flywheel I need the earlier 6 bolt, I'm looking to run N/A, the info I have gathered so far is earlier 6 bolt crank, standard 2.8 or 2.9 con rods and mopar 3.7 flat top pistons which need the gudeon pin holes opened up slightly but not sure what deck height i'll end up with so don't know if block needs decking or pistons need decking or no machining at all
