Hello.I'm not very sure what crank it is but i think its from an e36 bmw.We runnin different pistons too that had to be cut and valve pocketed. The compression was so high that it was pinking and we removed the head and dropped the compression but theres still a slight ping.I'll try and find out what crank it is but i think there are people that can stroke ur 2.7 crank to 2.8 or so.Donno not very sure.
