Need new crankshaft for 70 442 with 455. Where would be a good place to purchase. I see alot of places just was looking for some advice. Motor has some updates.

 

You might have better luck posting in the parts-wanted section. Good luck with your search.

 

Check these places
Rocket Racing ( bought one from them)
Dick Miller Racing ( great source for Olds stuff)
Summit ( bought one from them but at the time they did not have any drilled for four speed)
I'm sure there's more sources. I got less than perfect from Mondello (Lynn W)with no refund policy.

I bought a billit crank from Rocket Racing. Pricey but awesome. My last cutlass had one from Summit. No problems. If you can, get one that's drilled for a four speed, just in case you decide later to convert.

 

If you need extra strength Scat makes 2 billet cranks.
88-455O-4500-6800-2200 is a 4.5" stroke and 88-455O-4250-6800-220 is a 4.250" stroke.

 

Jw,

Is your crankshaft totally killed or can it be reground ? If it can be reground that is the route I would go as long as there is a decent crank grinder in your area. Stay away from crankshaft "kits" They are mostly all done by one or two big rebuilders and usually are not worth a darn.

If you want new Eagle has one, not sure about Scat.

 

crank has already been reduced so need new one thank you
