L05 OR L98 REBUILD?
I have been given equal opportunity in picking up an L05 w/ roller cam from a Caprice or an L98 from an 87 Iroc. They will both need to be rebuilt and unless I take them apart (unlikely) before I buy them I don't know whether they are a 4 bolt or 2 bolt main. Based on these facts can anyone tell me which has more potential?

From: Littleton, CO USA
Car: 82 Berlinetta/57 Bel Air
Engine: L92/LQ4 (both w/4" stroke)
Transmission: 4L80E/4L80E
Axle/Gears: 12B-3.73/9"-3.89
The L98 will have better heads. Other than that, assuming rebuild and cam upgrades are on the table, there isn't any difference.
Neither is likely to be 4-bolt main. That isn't a big deal.

Re: L05 OR L98 REBUILD?
OK. The guy just sent me the casting number for the LO5. It is 10243880. I checked Mortec and it specifies this block as a
350...95-00...2 or 4...Vortec truck, Gen.I crate motors and "ZZ4", roller cam, one piece rear seal
Now this doesn't seem to be an LO5 casting block. Am I wrong? The guy said it was from a 93 Caprice.
