The reason i was saying it don't seem like it would get off the line very well is the simple fact that with everything up top, by the time you start making some good power you'll be getting ready to shift and drop back under your powerband.
similar to how sowaidi was doing with his.
here's the video he posted.

obviously since your doing a lot of weight reduction its going to help significantly, but to me it seems like you could go a diff route with less work and have better results.
well no matter what its gettin tubed and fiberglassed

i know what u meen about the makin power part but i think the stall along with the lower than normal gear will keep it in the rpm range im wanting

on the vid what was his setup???

heads? cam?
why did it wait to boost so late?

i think alot had to do with when he changed gears u can hear him spinning and yea a stock 4.8 with sts and cam isnt comparable to what my setup will be
and i doubt he went to 7500

I think he just had a cam and sts. It boosted late cuz his cam was too big. it started boosting when the cam started making power. By that time it was time to shift. He was also running a 5 speed which definitely wasn't helping any.

true, but going from 6300-7500 is only going to take a fraction of a second in 1st gear and probably 1 second in 2nd gear.
You'll need to find some more mid range power some where.

Yea. i'd imagen a 215/218 would help the mid range

what stroke are you going to be running? I ran a 4" bore and 3" stroke in my blazer for a few months and it rapped out QUICK.
switched from that setup (302ci) to 4.060 bore and 3.48 stroke (360ci) with better heads and seen a HUGE power increase.

yea the f body guys have been using a 224/224 with good results but thats for a 5.7 so i think that one will do me well and those heads flow really well

yea it is just a second but if the stall gets me right back in the power band i should be ok
and the nitrous will help to

3.185 stroke 3.905 bore equals a 5.0
these guys make 540 n/a with big ugly truck manifolds pump gas and 11:1 248/248 590/590

If he uses the 400 tranny 1st gear is like the 4l80 1st. It will pull forever in 1st before it shifts. Once it does hit 2nd the drop in rpms will not be that bad. 1st and second are much closer ratios. If you are using a turbo it will not matter anyway. Once it is spooled up the gear drop won't matter. It will pull like a **** until you let off the gas.
