Engine builders: How do I determine stroke in my 383?
I've got a 383. 4.030 bore. 350 block.
The engine builder said he had to notch the block quite a bit so he said to get a stroker pan.
The compression is 12.1 or 12.2 after everything
I have SRP 140348 pistons, Eagle H-Beam 6” Rods, Eagle 4340 3.75 forged crank, Motor was bored .30.
My question is: what is my stroke? I'm asking because I don't know what oil pan to get. I'm trying to get one that will fit with my 64 chevelle and all of the stroker pans (safe side) won't fit, so I am seeing if a stock pan will fit.
Thanks

a stock pan will work fine for a 383 as far as clearance. If you want a bigger pan for oil capacity just buy one for your chassis you don't need a stroker pan for a 383. Hope this helps.

Dont buy a cheap oil pan from e-bay. Use a factory gm oil pan, they will fit. Thats all I ever use on mine and never had a problem. I have purchased the cheap pans from e-bay and they say it will fit the 3.750 stroke crank but it wont. Keep your GM all GM.
