Finally some new dyno numbers with new cam...holt crap, what a difference!!!!! All that has realy changed since my last dyno run what the cam and valve springs (since my 918's were not going to hang with the new cam). This is on the same dyno, so no Mustang dyno to Dynotjet to Superflow variances. Both runs were on 315 drag radials on 17x11 ZR1 rims, 3.73 gears, converter unlocked: Here you go:
Old setup: home ported heads (by me, but I'm kinda good at
)
TR 224 cam
Jet Hot long tubes
MTI lid
Full exhaust
91 octane
398rwhp/429rwtq
EXACT same setup, new cam
438rwtq/433rwtq
I'm totally happy with the new setup, the driveability has changed a little but nothing annoying, you just know you're got a cam in it now as compared to the 224. The 224 was great for what it was, but this new cam is just huge all over.

Would be interesting to see how much your ET improves. Hp looks great but your torque has changed very little. If you don't have more torque under the entire curve your et could suffer. Do you have before and after ET's?

Very impressive results! If that's with semi-home ported heads, I think the numbers would be scary with your fully home ported heads.
Can you share a few more details about your new cam?

Awesome numbers!!!!! Please post a graph I am considering upgrading mines from the TR224 but am curious of the torque curve. A few hours in the garage would be worth the increase if I don't have to give up too much torque!!!

I'll have some track times soon. The power under the curve is actually pretty damn cool. The peak torque numbers didn't change a whole lot, but they toqrue stayed up longer, if you know what I mean. Peak torque was at 4600rpm, for both cams, but at 5500 the new cam had almost 80lb/ft on the old TR cam. It just does not fall off at all.
The cam was a custom-ish one that www.cmotorsports.com ground for me. It's a 232/234 595/598 on a 113+2 Comp Cams XER lobe. I am still amazed. I heard about these guys from back in my LT1 days and they were the men for LT1 stuff, I didn't know they knew the LS1 stuff so well too.
Yes, I port heads on the side, my set was done in a hurry to get the car back togerther, but there's probably another 8-10cfm left in them.
