Thanks. I've also heard there's a possibility I may have a 4-bolt block as the fact that some "289" blocks were used in hiperf. applications. I'll have to check by the oil filter to make sure.

You're right, I'm enjoying the car and that's all that matters. Well, at least the heads are HiPerf! and most likely, LS-6 Heads.
