My friend has a datsun 710 with a blown piston ring. She was wondering if I could swap a new engine into it. Now....I know jack shit about nissan/datsun cars. So....can anyone point me in the direction of a possible swap? I don't have a welder, so something that would have little or no fabrication work would be best. I was thinking a newer nissan engine or maybe a small block chevy using modified JTR mounts .
