Results from Head/Cam install Just got the car back from getting my Patriot Stage II LS-6 heads and my TR224 on a 112 installed along with YT rockers, LS-6 oil pump, Spec stg. 3, and rollmaster timing chain, and I am dissapointed. My car dynoed a whopping 391.6hp. and a respectible 385tq. I have seen many on here dyno that much with just the TR224 cam itself (along with most bolt-ons of course). I do realize that I am missing a few bolt-ons like underdrive pulley and a ported TB, but I cant see it giving me the #'s that I was expecting. Larry at Speed Inc. said that the car felt really strong but maybe that it just wasn't a dyno queen so I dunno. The car does pull like a freit train, but I am still dissapointed that I didnt even hit 400. I thought I would atleast get 410 at the least. I will post the dyno graph later on at a friends house who has a scanner. The A/F was right at 12.9-13.0 across the board, so I dunno what the problem could be. Any suggestions guys?

You'll pick up 10 HP with the ported TB. You are also dynoing with cats...most of the cars here aren't running cats...high flow or not you're leaving 5-10 HP on the table. The UD pulleys might be worth something on the dyno...most say you can't see the gains of a UD pulley on a dyno but they are worth 0.1 at the track.
A cold air/ram air type induction (FTRA) may be worth a few HP as well.
What gears and rear do you have...deep gears can suck some HP.
If you're really searching for the power, maybe you should do a compression test to make sure your rings are good and the valves are seating properly.
I'm just throwing out ideas here. If Speed Inc can't find you some HP on their dyno...there probably isn't much else there without buying more parts...TB and UD pulley.
I wouldn't sweat it though, take it to the track and see what it runs, that is the real test anyway.

We just installed a TR 224 with a set of TEA 1.5s last week. Car made 417/409 THROUGH cats and a full exhaust. It did have a TB and pulley fwiw...It also had 4:10s and 315s out back....
How old are your heads? Patriot said they were having some problems a while back with valve jobs and have since rectified said problems. Could be possible you got a set of the heads from that era??
Goodluck to ya, Im sure you can find the missing power.

Don't feel bad, I only did 394/372 with a 228R and PP S2 5.3 heads. Thats with a pulley, TB and every other bolt on...FWIW, I got my heads at the end of July/beginning of August of 2003. I am doing alot of research on my next combo I will be doing later this year.

I think it would be easy to nudge it over 400rwhp (if thats all you want 
) with a few small mods like the ported TB, maybe trying a different lid if you can borrow one from a friend. Ditch the cats if you can too! 
With the LS6-style heads you should see a little difference in the midrange over a LS1 ported head. Although I would have gone with PP 5.3L heads with that particular camshaft.
Edit: If you have the time, try dynoing with stock rockers instead of the YT.
