Sweet. I'm glad to hear the stock injectors are holding up. I was worried mine wouldn't be enough. Do you know what duty cyle they are at? What did the car put down rwhp/rwtq?
I wanted Rapid to build mine but got a Texas Speed.

Wow, congrats. 130 MPH traps NA with a 3700 lb race weight is nuts. Imagine that combo in my car with a 3400 lb race weight. If (when) I get a 402, Mikey will be building it.

These are promising results, I am going to have a 402 built myself after having a problem with my stock bottom end AFR's are on teh bill as well as teh fast 90/90.
Do you think that the 1 7/8 headers are needed, or were you already runnign them? I already have 1 3/4 QTP's and was gonna at least try them to start, and try a cam in the 242/248 rance, maybe a little more lift then you are running.

I was thinking of doing a solid roller LSx motor in the future so that's why I ask. Where do you shift at? I've gathered that with the EFI Live you are using, one can make the stock PCM go to 8K.
