Some of you have seen my current project on other boards. For those who haven't, here are the details.
Decided to sell the six stuff and put a big block in it that we had sitting around. It's a budget motor w/ rods and pistons,
stock closed chamber crappy oval ports, hyd roller (small). We built mild steel 1 7/8ths headers and crossover, w/ a 4" ss downpipe
that switches to 4" alum. at the v band before the firewall, and continues 4" alum exhaust to the muffler w/ a turndown in front
of the rearend. I used the Cotton's air to air that came in the car when I bought it, and we're blowing thru a C&S specialties
billet aerosol 4150. Magnafuel Pro star 500 pump w/ a C&S specialties boost referenced reg.
Running a msd digital 6 w/ their boost retard box.
I put a T400 in it w/ a brake, and a 9" w/ wilwoods out back spooled w/ 33 spline mosers.
Wolf Anti roll bar, wolf uppers and metco lowers.
I'm hoping for mid 9's w/ the current setup.
Thanks to Tim @ vandpracing.com for building the downpipe and exhaust, and helping w/ all the bs as I built it.
Thanks to Wizzle for busting his ass for 3 straight weeks doing most everything else and doing the headers and crossover.
The build took about 5 weeks from when the first bolt was turned to start removing the v6 stuff to when we dyno'd w/ the new setup.
We went to Chad's dyno (Modified by KC) twice to make sure everything was happy.
First dyno pull, 456rwhp @ 8lbs and off the chart rich
Second dyno pull 656rwhp/ 660rwtq @ 15lbs w/ af's in the 10.8 to 11.2 range
Third dyno pull 751rwhp/ 715 rwtq @ 20lbs w/ af's in the mid 11's and 26 degrees of timing
Went back to the dyno last saturday and went to 22lbs and 25 degrees and made 762 rwhp/ 705tq,
af's went lean at the end, but we jetted it down trying to clean it up, we'll put a few numbers
back in and it should be happy.
Ready to take it to the track and see what it'll do.

You'll get there, keep the good work. Sounds like there is alot more in it.
