265-275 because of the compression bump if hes stock cams and long tubes and full bolt ons

I would aim more for the 265ish range though...

more if he has cams

To clear some things up. I know the gears and driveshaft don't add anything but I just put it in there because I asked me to post all his mods, so I did. The heads are stock they were just cleaned up a bit, no port or polish. The cams are stock '00 cams that came on the heads. The Manifold is a PI manifold. ALSO he wont have headers, maybe later on but not for a couple months.

BTW, I told him that its better to predict low that way you wont be disappointmented, but he insisted he likes to predict high.
