The "Olds" 350.....

[FlatBlack4Life]

Is there anyone that knows are has some input to say about creating a "383 -like motor with an Olds 350. What I'm asking is if there's a combo of parts that can be used to create a motor similar to the Chevy 383?? I know this might be a stupid question, my apologies.

Also has anyone built up an Olds 350, and have any recipes, or tips/tricks?? Thanks. :thumbsup:

I've never heard of anyone doing this, but here are the three cranks available from the factory.

Olds small block (330-403) 3.39"
Olds big block (early400-425) 3.98
Olds big block (late400-455) 4.25

I'm guessing the 425 crank (3.98) would fit in the 350 making it slightly smaller than 400 but I don't know what sort of deck height problems you might run into.

Just for giggles, here are bore & stroke numbers for Olds:

260ci 3.50X3.39
330ci 3.94X3.39
350ci 4.06X3.39
403ci 4.35X3.39
400ci 4.00X3.98
425ci 4.13X3.98
400ci 3.87X4.25
455ci 4.13X4.25

Hope this helps!
