Awesome bro. Funny though my 2000 FRC with pro longtubes, 78mm FAST, and g5x3 on a 114 (I think) made barely 400 rwhp 380 rwtq. Your under drive pully must've helped some but doesn't explain the big difference in power. I see you have 7.425 pr's, I have 7.4's What's the difference ??
On a side note my FRC was a factory turd, bone stock made 300 rwhp 300 rwtq. Worst tune ever from the factory.

Difference is the length duh !
just kidding.I wouldn't call 300rwhp stock on the OEM tune a turd; I'd call it very average. I had a 100% stock 01 M6 F-bod this week make 302rwhp on his OEM file. Before the pull he asked me how much it'd make. I told him 300-305...
Though, fwiw, I tuned an 02 WS6 with 35x3 on a 114 LSA, QTPs, ORY, Borla, stock MAF, no pulley, no other mods and it made 409 rwhp and 385ish (dont remember the exact tq number but this was close).

The length, haha good one.
I asked because I see many engine builds calling for 7.375, 7.400, 7.425 etc pr's and I was wondering what necessitates the need for the shorter or longer pushrods ??? Good joke Frost, lol.

As far as 300 to the wheels bone stock my buddies 2000 coupe made 320 rwhp 325 rwtq (M6). I was quite surprised. However when we compared the amount of timing that was in the factory tune (8*'s) more advance in his tune clearly explains his extra hp.
Before result's on the same dyno . STD uncorrected 1.02 , SAE corrected 1.00 .

It drives pretty good considering , needs a little more technique taking off from a stop than before but thats to be expected .
Once rolling I can put it in 5th going slow without chugging . This is my first cammed LS1 car but not my first cammed vehicle .

nice results and nice overlay writeup. I got my cam a few months ago, a little smaller then yours, no LS6 intake, and you do have true duals so you have better results then me 
haha. With better intake/tb and heads wicked setup.
Ever think how well a fully built 346 would be with that many miles on it?? Mine is roughly at 78k and I started looking at if it's worth building it up or leaving it and waitin for next block haha. Wow and those numbers are through a beefy rear end and big clutch.

I felt a decent SOTP difference when I switched to a LS6 intake . Where before it would only spin in first and get a little rubber in 2nd then hook , after it spun in first and 2nd pretty bad .
This was untuned with bolt ons but definately a difference though , bought mine used from a member here for $350 shipped . You would see a similar gain .
It has some miles on it yes indeed but when I pulled the cylinder head's the cylinder bore's still had a nice crosshatch pattern evident . Mine does not use much oil , I add maybe half a quart in between oil change's . I plan to go through the bottom end eventually .
The rearend is only a 31 spline , trutrac diff so it's not as power robbing as a 35 spline big dog model . I doubt it robs any power .

Yeah i know i definnitly need a new intake mani I just can't afford anything right now haha. Oh wow 31 spline didn't know that, i thought they came with 33 spline.... I think I am going to be gettin a 35 spline so I will get hurt haha.
haha.
