JP,
If this is the L05 engine, it's a fairly plain-Jane 350. .385"/.403", 184°/194°, 114 LSA roller cam, but a decent 9.8:1 static compression and 195 HP - 295 lb/ft torque out of the box. Given the respectable compression, a better cam would be an improvement. The iron heads are no real asset, either. Equipped with 1.94/1.60 valves and fairly small port volumes, they probably flow about the same as a pair of stock L98 heads, maybe just a tad worse. One-piece rear main, center-bolt covers, self-aligning rockers, and all the things you'd expect on the last version of the SBC Gen I engine.
This engine will probably be a big improvement over the LB9, and the price for a NEW engine with gauranty is hard to beat. You could easily spend that much on rebuilding a bone-yard 350 to get it to the same point. If you know of someone looking for a pair brand-new of 350 heads, you could actually make a little cash back. If you don't have better heads to install on the engine, there are several ways to massage another 30-50 HP out of the stock castings with the ZZ3 cam profile. For an extra $250.00, you can go with the screwed studs, larger valve spring seats, and larger valves and deep-ported bowls, then machine in from the intake side to improve flow. Of course, some of this would be done by you, unless you're willing to spend $500-600 on head work.
If it's not the L05, never mind...
