Ok i need to ask as i to have been sitting on one of these cranks for 10 years, I have a fresh machined 30 over 340 block, any input on what pistons to use with this crank, it has been very hard obtaining any info on this crank, I have a set of custom pistons that were made years ago from diamond racing, but the shop went under and i never really know if they would work? the custom piston card says , bore= 4.070, comp height = 1.704, effective volume= -6.8cc, valve depth intake 0.292, exhaust 0.224, piston weight 561 Grams, Top ring 1/16 2nd ring 1/16 oil ring 3/16 my wife had them made as a gift and surprise under the direction of the shop owner but it went under some time ago. Thanks for any help.
ps trying to figure if I can use this or look for a diff crank and piston combo?
