Let's try another angle;
Two choices for "raw material", a BB Chevy and SB Chevy.
What would be more interesting;
<span style="font-weight: bold">`70 style LT1</span>
--Built with period Day 2 parts? (Ported heads, bigger cam, vintage intake--maybe even a tunnel ram?)
--Built with stock parts but with some "bag of tricks" tweaks added? (think along the lines of "Pure Stock"
--Built with stock parts but with every trick in the book thrown at it? (Think along the lines of "F.A.S.T."
<span style="font-weight: bold">`69 L72 or `70 LS6</span>
Same criteria as above.
