Chrysler LA / NASCAR 355 cu. in. crank shaft

mark_mopar said
I recently purchased a lot of Chrysler parts from a guy who claimed his grandpa was a NASCAR racer. Looks like a have a 355 cu. in. crankshaft for a small block LA. I have another crank that looks just like it that came in the lot i purchased, but I can not confirm its specifications yet.

What do I do with this crank? I really don't have a use for it. What's it worth? Who can use it?

Could they be left overs from the 90's when Dodge ran in the IROC? Those engines were 355 ci and I think they were based on the 318 block. Get out the micrometer and check. They may be a great start for a killer street engine.

Yes, right after the Camaro/Z28’s.

The actual block used I know nothing about. Though I’d bet it was a MP race block that was used. I also have a rotating assembly that I got in a parts deal.
(A all or nothing deal.)
MP also had matching pistons to the crank. The pistons and crank used stock length rods.
The total CID I have is 352. (4.03 pistons)
The crank is an 8 bolt flange

So, in order to use for his set up…. A race block = $$$
318’s are unlikely to go to a 4.03 bore (never say never) and sleeving down a 340 is nutz in cost just to use this. I know there are parts to insert in the crank journals of a 360 block. (If you have the small journal unit which I’m not sure if there offered in both journal sizes) Hughes engines has them though I did see them cheaper elsewhere. IIRC, Ramracing engines here in the states has them. IDK about destroking a 360. I guess if you were an active racer…. It would make sense. For a street guy, maybe not so much.

If someone wants rear crank measurements, let me know. I have to dig it up and out. No issues doing so.
