Adding G5X3, port matched LSX, EWP, & more to my TEA heads! 470rwhp? 
Doing some top end work as we speak!
- Fixing 7 bent int/ex valves
- Swapping out TR230 cam for a much larger G5X3 cam (flycut of .065).....I've "heard" it's a 239/245 .62x/62x but who knows.
- Adding port matched (to TB and heads) 78mm LSX intake
- Adding Meziere EWP
- Adding Crane 832 dual springs to cure my valve float and handle the bigger cam (good to .650 lift)
- Adding comp R lifters for safety
- Adding HAL R-Series shocks in favor of the stock shocks/springs that I've had for 42K miles so I can actually transfer some weight at the track.
Now with 4.10 gears in the 12er, I'm hoping to see close to 470rwhp/420rwtq on my old *** heads
...I think somewhere in the 460's is probably more realistic.Wish me luck!!! I should have dyno #'s by the end of the week. All the mods are finished except for the valves being replaced. I'll keep you all updated
Thanks to Xtreme Motorsports, LG Motorsports, Thunder Racing, and TEA for all their help. All top notch companies!

Hey Lou, did you guys port match the intake to the heads? Was the TPIS intake port matched to the heads?
Great job guys, keep pushing that envelope!....really makes me rethink about going to a 90mm setup now
so where are all the haters now who complained this intake was crap?

Good luck,I am thinking you could see 50 rwhp easy.My unlocked auto made 446 when the FLP Y pipe was dropped,I want to get a FAST intake on mine with a 90mm TB,should be good for 15 rwhp.
Keep us updated,hope to see you real close to 500 rwhp.

1. Only 10.8:1 compression (I'm leaving a little hp on the table there)
2. No short belt (which Lou had on the car that dynoed 503rwhp)
3. The 78mm intake/TB seems to be the bottleneck with these bigger heads/cam cars.....
4. I'm running 1.5yr old Stg. 2 5.3L heads, not the best LS6 heads that are out (10rwhp-15rwhp left on the table).....(TEA, if you want to send me some Massengale LS6 heads you have my #)
5. My dyno graph will have full smoothing
....just kidding LG 
6. 12 bolt w. 4.10 gears

Well, I don’t think you’re going to get 20 rwtq from just an intake/cam swap. If anything bigger cams will give you less torque and the 4.10’s will rob you a bit of torque as well. I think you’ll pick up maybe 5-10 rwtq and 15-20rwhp max. EWP’s from what I’ve seen generally pickup 3-8 rwhp, and then another 10-15 from the intake/cam. As you said yourself, your heads are pretty old and to get the most potential out of a larger cam you’d need better/bigger head and a 90mm TB. So I’ll guess ~455rwhp and 405-410 rwtq.

Verbs' ricer math:
I figured 5rwhp/5rwtq for YT's
5rwhp/5rwtq for EWP
10rwhp/10rwtq for intake
-5rwhp/-5rwtq for 4.10 gears
15rwhp/5rwtq for cam swap
That's where I came up w/ my figures
....a 30rwhp gain and 20rwtq gain

you have electric water pump, no need for a short belt..
