Looking for some insight

Basing it on a weight of around 3400 all in? and 340-ish fwhp I too reckon 12.55's@107, as an example>
My '71 340 Cuda with around 9.5:1, stock 2.02 iron heads, a weight of around 3550lb with me, a DC .590" SFT cam, strip Dom intake, 850DP, 4.30's/4200stall, 1.75" race hdrs, 10x28 slicks and stock leafs w/snubber went a best of 12.40@108...=368fwhp.
