I'm hoping for alot better than 13.2 with that kind of power, I love my classic truck weighed in at 3960lbs after the swap I want around a 12.5 if it can hook up but still thats a great time with that much weight I run a 13.6 now with only 323hp and 342tq at the wheels rwd

I would hope for more than 13.2 too but thats through a AWD. thats pretty good for all the extra weight and drive train loss

You should be able to go lower than 13.2 if you really are making 430awhp. An awhp number would be after all the drivetrain loss.

Yea, start at 6500 and work your way up.

I think my truck is atleast a 1,000lbs lighter not sure of the exact number, Ive seen specs for some of the newer trucks weighing in at 5K without awd

Yea andy's race weight is just north of 5k. If you're 1k lighter with that much more compression you'll be running 12's no sweat.

For that price it seems like a ported intake may be worth your while. You're right, it would be a shame to get this all together only to have the intake hold you back a little.

the cam really shined in the upper rpm. I dropped .4 in the 1/4 just by upping the shifts form 6300 to 6800 and adjusted the afr from 11.8 to 12.5. No timing changes.
And my race weight is right at 5300lbs

Thats crazy! I think with a pretty loose converter it helps a ton to have a cam that can really eat up top.
