Hi all.
As stated just looking at the aprox cost for a 304 355 crank. I know it will be above 70% of the new crank price. But is it 95% or 70%?

Thanks.
Shane.

.. index grind of a V8 crank ?
$300-350 mark
straightening?.... oooh
that will not be cheap

I would talk to a specialist (Crankshaft Builders for example)... and ask them

Yea just want a rough idea so I can make sure I have the cash in the bank when I call. It's a scat 355 crank that stopped dead when the rod hit the girdle after tearing the block up. Can probably grind it back in line and use holden rods but I would like to see if I can get away with chev over size bearings for the rods.

It's an old engine that I pulled apart 5 years ago. Plan is to get new valves and rams heads to radius the seats on their Newen CNC seat machine and get them to do a bowl job and port match nothing major. I want to run a TP low rise dual plane and carb, yes it's not ideal for power but thats what I want because it looks old school. I'll find some decent but cheap rods and pistons chev will be good for this just hyperutetic and forged I beam. Cam I think a 6500rpm flat tappet will be the go maybe solid too but I'm a lazy mechanic so it'll end up being hyd so stock rocker ratio in that case.

It’s not worth trying to save. Better off buying another crank for the $400 or so.
Could you please let me know which is the best place to buy one from? Rocket ind?

I got mine really cheap from vpw when they had a sale on.
Thanks. they're selling for $472. But if I can get away with a regrind for $300 I might go that way.

Keep in mind that you can’t always see metal fatigue or stress. I wouldn’t even chance it - but any decent engine shop will probably tell you that anyway.

I was planning on using crankshaft rebuilders. They will magnaflux it.
