Wich MFG BBC Crank to use

[retromek]

For 8-12 psi what Crankshaft MFG Holds up best under 6500RPM?

Shop who has built 2 engines for me and a few for other friends recommends Lunati or Scat without dumping big $$$$ :) Doesn't like Eagle stuff. Say's it's made in China, personally don't know though :confused:

Scat is made in China also. Machined in the USA
There are several Chinese forgings machined in the USA that are decent. I have never had a problem with reliability or durability.
A Callies Dragon Slayer (cleverly named) is 100% USA and priced to compete with the Chinese stuff.

Eagle in mine has held up so far with a lot of boost.

I run a LAE billet now but I had a Callies in my last lake boat with a 498" BBC with a 350hp nitrous set up. It was bullet proof despite numerous motor rebuilds due to detonation causing ring land failures on the pistons. I agree with Info. in that for the price, Callies is hard to beat. Good luck with your decision.

have had great success with eagle's good stuff.
now have a bbc at 13lbs of boost with no probs. Just make sure all your clearances are perfect!!!!

no cracks?---must be a tough piece to pull a 14/71 with a big cog belt and no crank support!!!-----I'm impressed

This is the second season on this crankshaft without any problems.

I'm running a Callie's Dragonslayer. I think it's a great crank for the money.
You can order direct from Callie's(419-435-2711). I dealt with Don there, and he set me up a with a tough "rotating assembly" at a competitive price.
