Tech QuestionCraig Rocksvold, Waukon, IA, 1972 Plymouth Cuda 340 I have a 1972 340 engine with a cast crank and wondered if
a crank from a 318 Poly will bolt right in? I believe the Poly's crank is
forged, correct? I plan on building the engine like a '71 or slightly
beyond. Behind the engine will be a 727 with a 3.23 Sure Grip. Your answer
and advice would be appreciated. Craig- Depends on the year. As long as it's from a '62-up engine, yes, it will bolt in. But many of these cranks have a bazillion miles on them, I suggest having it checked for invisible cracks (Magnaflux) beforehand. I should also mention that for outputs in the stock or near-stock range, the cast crank is 100% OK. Rick
