NOS 3.51" mopar stroker crank in a 318?

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?

In your situation ....your 1.704 compression height is good....

3.51/2=1.775+6.123+1.704=9.5882.......340 block should be around 9.60 deck height....piston would be down in hole about .018...

have the block squared and decked to 9.588...or run it with a thin head gasket....028
