Need help

OK, I want to make sure I am right on what I have.

I pulled a 5.7 out of a 1997 suburban, engine code is R and build date is 11/96. So this is an LT1 correct or is it an LS1?. Reason I am asking is I am rebuilding it and I am trying to find the rod bearing and main bearing clearance specifications.

Thanks
Mike

And yes I am still searching for this info.

If it's a 5.7 liter motor here are the specs for the clearances.

Connecting Rod Bearing Clearance (Service) 0.0010-0.0025 inch

Crankshaft Bearing Clearance (Journal #1--Service) 0.0010-0.0020 inch

Crankshaft Bearing Clearance (Journal #2, #3, and #4--Service) 0.0010-0.0025 inch

Another question. I have a buddy that has an older 350 that has been stroked to a 383 and runs. However, it is carburator. Could I bolt my intake on it a go fuel injected or would I have to do more like bolting the heads also?

SBC, 350 CI. More than likely it's a Vortec.
