what's the average HP/ TQ of a lightly modded 99-01?

[Keith 5.0]

I'm trying to figure out how much HP I'll be making after putting my new engine together. My combo is:

rebuilt 99 DOHC heads, fresh valve job
99 teksid block, standard bore
JE flat top pistons- 10.4:1 CR
Moly file fit rings
Scat 4340 rods w/ARP 2000 bolts

FMS ceramic coated shorty headers (might be getting mac LT's)
stock midpipe (might be getting mac prochamber)
magnaflow cat-back
steeda underdrive pullies
Mac CAI

I'm sticking with the stock TB/ MAF until I get a nitrous kit for the car in august. I'll have it tuned with SCT software when I get the car running.

Anyone have a similar combo that could tell me around where I should be at? What should I expect to gain by adding LT's and a prochamber or Dr Gas?

The car dyno'd 291 rwhp & 3XX rwtq with:
stock internals
bassani catless X/ bassani catback/ FMS shorty headers
mac CAI
4.10's
(untuned)

my numbers are in my sig and that was with just the K&N and a 70 degree day.

I've gotta get back on one with my tune and JLT.

I'd say you're anywhere from 320-340 rwhp assuming everything is put together by someone competent, looks like you're limiting factor will be the stock intake, and you should pick something up with a mid pipe, so I'd say in the 330's would be a decent guess

I'd say the pistons are worth around 15 and the UDPs another 3-4 max, so you're now looking at about 310 rwhp without a tune, and another 10 with the SCT. The Bassani/Magnaflow is essentially a swap. Your bottleneck is the intake.

Dyno'd at 301/303 with Dr. Gas and full boar mufflers (and 4.56s, but they don't count).

well, I bought some MAC LT's & a Prochamber today. Any idea as to what I should expect HP/TQ wise now that I added these?
