Another oil question

[furyus]

I'm finishing up my 505 stroker with roller cam, lifters, and rockers. What is a good oil weight for this engine?

I use a Rotella 5-30 full synthetic on my 496. But your best bet is to ask your machinist since he set the clearances.

I'm using Penn Grade 20W50 in my 512 stroker. Hyd roller cam. ruffcut

I use the same in the 500 inch MW in the 63 Fury Solid roller cam.
512 is a 10 to 1 Compression street build and the 500 is 13 to 1 race only.
