Where do I go next??????

[americanmusc1e]

OK, for lack of a better way to say this, I will list my specs. Please tell me the things that are slowing me down the most. starting with the cheapest to fix first.

Would anyone here use nitrous on this engine???? (I have my entire savings into this engine and I can't affford to break it.)

any ideas on what rpm to shift at???

is the stock HEI slowing me down????

Eagle H-beam rods 5.7
Hyperecutec Pistons
Vortec heads (home ported)
Comp cam .477/.480 lift 224/231 duration @ .050
stamped steel 1.6 roller rockers
1 5/8 headers, full dual exhaust
Weiand Stealth Vortec Intake
Holley 600cfm VS 4160
stock HEI dizzy

Transmission:
700r4- built with shift kit and upgraded cutches and bands
2000rpm TCI converter

Rear End:
not totally sure on the gears, 3.08 or 3.42 open diff

Tires:
Maxxis Mudder 31", a little stickier than a street tire (but I still do one-wheel burnouts for 100')

I'd like to throw on a pair of AFR 195's and a bigger cam (THUMPR 287??), and pick up another 75-80 hp, but that would cost way more than I can afford.
