I noticed the cam was the biggest advance of power. Why so much? How much would that cam go for?

------------------
1992 Pontiac Firebird (stock)
- 5.0L V8 TBI / Automatic Trans / Every option, excluding leather
- Killer car audio system:

• Aiwa CDC-MP3 head unit
• Rockford Fosgate 360a2 amp
• pair of 12" MTX Thunder 5000s in a custom box
• Pioneer 3-way 6x9s, soon to add more more more!

 

Well, dyno results don't lie. But I don't think you'd see that much improvement with stock heads and exhaust.

That cam for that car (hydraulic lifter) is probably in the 100.00 range and that may also include new lifters too, but for your motor (hydraulic-roller) probably over $200.00 for just the cam.

 

Yea, that and they set the initial timing at 16 deg BTDC. Before the cam swap they made no mention of changing the timing from the 22 total timing of the stock setup. I'm sure that alone helped a lot after the intake and carb swap. Then add a great cam to the combo, and vvvrroooommmmmmmmm!!! POWER!!!! It's all in the combo. Like 8mike9 said, you would never see that amount of an increase with stock heads, intake, and exhaust by using that cam.
