Dyno numbers for 5.3 Malibu Put my car on the dyno today..
LM7 130k miles
pacesetter 98-02 f body headers
Trickflow 220/224 cam
3in exhaust with h pipe
4in cold air
TH350
3600 stall.. unlocked.
Car made a best of 321 whp and 312 wtq.. a gain of 21 hp and 6 lb ft tq. There are spots in the middle of the curve that netted another 8 hp increase as well. EDIT: The gain was over my mail order tune, not from a stock PCM. If the pcm were stock with this setup, I would imagine that it would have made way more than just the 21 hp.
More importantly, numbers are just numbers, I am happy with them. The car drives flawless and is extremely quick. These cars make easy power with bolt ons and cam swaps.

Casting 862. Here is some good information about GM LS style cyl heads. Everyone wants to toss the truck heads in favor of LS1 heads.. well, not only do they flow within a few cfm of each other, they will be loosing compression from the bigger combustion chamber. The only cost effective bolt on would be an LS6 head milled to compensate for combustion chamber size.
Since I have a 5.3, L92/LS3 setup is not an option unfortunately as they make wicked power for such an easy upgrade.
706 and 862 flow about the same.
