Just curious to what everyone thinks this combo will make on my 98 Formula WS6;

PRC stage 2.5 5.3 heads
MS3 cam (cut on a 112 LSA)
FAST 92mm intake
92mm TB
SVO 42# injectors
255 lph fuel pump
SLP lid with K&N filter
SLP crank pulley
ARH 1 3/4 LT headers
ARH ORY
Magnaflow catback

Car is a 6-speed with the stock 3.42's in it. Mileage is at 96,000.

The remaining parts are currently on the way, and with any luck everything should be done in 2 weeks. Hopefully I can get it tuned right after the install is done to show the exact results.

RWHP guesses?

damn, i think your getting lowballed!! I'll guess 440ish, I mean a ton of MS3 cars go over 400 that paired w/ those heads and a proven Fast 92/92 that would be my guess!

Wow, you guys are guessing a lot lower than I hope to be. Perhaps all these other guys with pretty much this same combo are just seeing rare numbers;

Not to mention this is the same setup Jon from TSP has on his car that did 475 RWHP (given that was probably ideal dyno conditions at sea level)
