Default Well its finally done!

RCSB, with a stock bottem end LQ4 with all ARP hardware.
I cut 0.050" deep fly cuts in the pistons to accomodate for a BIG cam change if ever desired.
0.020" milled off the heads
0.040 cometics put me at about 10.8-1 or so,
225/229 .580 .590 on a 114
Pac 1518's.
Stock intake with no EGR,
42 lbs. 8.1 marine injectors,
1 3/4" longtubes with full custom 3" duals (NO CATS) that dump at the rear axle with 3" V series mufflers.

I've got a built 4L60e trans with a Pro Truck 3600 Yank.

I wanna do a gear swap in the future but I will be spraying and wanna see what kind of time and MPH I get from the 3.73's on NO2 before I change gears. I am hoping for 350-375 rwhp on motor. No CAI, NO underdrive pullies, or any other crappy bolt on's, or snake oil!
ANY PREDICTIONS?????

You'll get more responses if you separate things better in your post. Maybe edit it with a quick simple mod list and some info on truck (RCSB or what)

Depending on the tune, weather, and traction, I'd expect anywhere between 12.5 and 13.2

Thats cool I was wondering if I'm way off on my RWHP numbers (to optimistic), not so much times. I'm gonna spray it down to mid 11's at the track. There seems to be alot of guys on here with similar setups hoping for some input.

Your dyno numbers definitely sound reasonable.

how is it you consider a CAI a crappy bolt-on? jc...

but other than that it sounds pretty decent

Most CAI's do more harm than good. Mine sucks because the IAT's jump real high when sitting in traffic. I just don't want to waste more money swapping to a better one, so I will probably just relocate the IAT sensor.

Thats why i said "oh ****" when you opened up your hood lol. I used to run that same intake and it did the same exact thing. Luckily i found that Outlaw intake i have now in a group buy.
