I'm with custom; I got my car for free and I can spend as much as I want on it to fix it up. Just like having a new car w/o monthly payments, just need to make payments to GM for new parts lol. But yeah why don't you get a 3.1 instead? From what I know the 3400 engine would be best.

There is not much difference between a 2.8 and a 3.1, other than .32" of stroke, So if a 2.8L is easier to find then it is a viable option, if a 3.1 is easier then it is viable, a 3100 or 3400 is nice but requires more custom work.
I am actually considering getting a 2.8L for the crank and make a higher reving gen3 V6 or rather potentially higher reving, among other reasons.
