Hey guys i am looking into a destroked motor, and looking for a 327 crank.
what aftermarket brands make a good 327 crank? or if anybody has one laying around, good stock, or aftermarket, shoot me pm and lets talk.
any recomendations, this will be a claimer type motor, with probally h beam rods, maybe good i beams, an srp piston.
large or small journal can work.
thanks

If you're turning over 6500, something other than a cast crank would be advisable. Even an Eagle or Scat steel piece would be a step up. If you can afford it,and rpm requires it, Callies, Crower or Lunati have 'budget' lines that go for around $750.

I'd stay away from stock steel cranks. They're marginally stronger than stock cast cranks, but are prone to cracking. With the last 327 having been made over 35 years ago, I wouldn't risk a used crank in a race motor over 6000 rpm.

My father in law has a COLA small journal steel crank that he may want to sell. Post back in here if your interested and I can hook you up with him. I considered using it in a 400 block to make a 362 out of it, but built another 355 instead. The crank is a 3.3" stroke.

i turn 7500-8000 with my stock lg journal crank all season NO PROBLEMS and i wouldn't advise anyone to entertain the thought of a scat (junk) if worried about it have it mag fluxed but they do have to be balanced to turn that not thrown together i doubt that he is going to be making over 500hp so cast will be fine also he said that it was for a claimer motor

I noticed the claimer thing... but H beams and SRPs in a claimer?

Anyway.. if ya wanna risk $1000 worth of rods and pistons on a 35 year old crank, go right ahead. IF I was spending that much on the rods & pistons, I'd spend the $500 for a 4340 Eagle crank. Or $750 for a Lunati Sledgehammer. Now running stock rods with $200 pistons, then I wouldn't think twice. If it blows, no big deal.
