Where did you purchase these??

WHEW, I finally got through this whole thread. I think there are a lot of people out there, including myself, curious to see the test that John02SS was going to perform.
Thanks for those who took the time to really make informative and pertinent posts. I put my FAST 90 (unported), NW TB, and Halltech stinger on at the same time. My gains were from 399 RWHP/ 390 RWTQ to 422 RWHP/415 RWTQ (the difference between the first and second curves on the dyno graph seen here: http://i6.photobucket.com/albums/y21...6biggercam.jpg)
After camming up, my car is currently at 470RWHP/415RWTQ and I was trying to read up on porting options. John, if you ever did the tests post up!

At a certain point in time, going to a larger camshaft just pushes the power band up the rpm range. Case in point, he didn't gain any torque, but carried the torque up the rpm window, gaining good amounts of hp.

Correct, with the 3.90 gears I have, they were crying for a bigger cam to get a much more usable powerband. Instead of dying off in the middle of the gear, the car now pulls til about 7000 rpm. Much more fun for racing!
Also, as I posted before, we did a pulley at the same time- which adds some HP but takes away TQ.

TIA...
Adjust your cables. I finally got my buddies car to stop sticking after noticing it was a traction control car and it was sloppy on the TCS solenoid. Adjusted the cables there and BAM SOB was fixed. This may not be everyones problem but it could use some attention. It may also only be on cars with TCS that they are sticking on. I dont think I ever found out exactly what cars the people had the these things were sticking on.

what do you guys think of this 78mm FAST port job I purchased this FAST 78mm allready ported from a LS1tech member. (I still have a 346CI on stoch 853 heads.
He told me it was ported for stoch heads ?
I've noticed softness on the bottom end but a nice gain in mid and upper RPMs.

just started work porting my fast 90. I have the lower intake bolted to my AFR 225s on a mockup motor. I have not started on the inner piece. I would like some input on where I need to port the inner piece.
here are some pics of what I have done so far!
