Thanks for the thoughts. I'm not married to the SBC, but the cost of the
LS1 may be too much. again, my plan is to buy a (crashed/ugly) donor
car...if it only comes in a 'vette, I don't think it will be cost-effective.
what cars would have the suitable engine(s).
re: smog
we do have testing; the 86 body would only require minimum specs. the newer
donor car would easily meet them, I suspect.

Gonna venture a few opinions though I'm no expert on the subject...I
thought the Jag V12s got the Turbo 400.

The best choice engine-wise, of course, would be a fairly recent
LS1/LS2, but I'm not sure how far the kit guys have gotten with the
LSn-series motors.

No, the Jag V12 is a 60-degree aluminum motor and not all that heavy.
About as heavy as an iron SBC, I think. A bit heavier than the LS1/LS2.

Any LS1/LS2 you can find will beat those numbers by quite a lot.
Do you live anywhere that smog legality matters?
