Default 5.3 Swapped 81 Malibu Dyno

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
Stock truck intake, throttle body, injectors and 862 heads

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.

Not super high numbers but your power band looks like it would make for a fun little street car with the 3600 stall and gears.

i was expecting about 15 more hp and tq, but these numbers are corrected and my tuner said the stall is the reason for the lower numbers

Car ran 13.66 @ 105. Un-prepped track resulted in a 2.39 60'. So there is at least half a second in the 60' alone. Shifting at 5800 rpm.

I really think with some good tires (I'm running a 235 street tires), getting the 60' time down to a 1.80 or so, and moving my limiter to 6500, I should have a mid to high 12 second car.
