any tips are greatly appriciated, I put the general topic above question.

Fuel
1. is a stock fuel pressure regulator on a 350hp motor OK? (had one but seals went bad, cant afford to fix/replace) drove it with gauge in veiw hold 35psi at idle/no throttle, 40psi through out the rpm range which is same way I set my old bbk, so it seems pointless to change. (stock lines, 255 in-tank, 24lbs)


Fuel
2. car is way rich on the low-end (under 3,500), pulls hard above 3,500 though. I think I have a leaky injector(car sat 5 years) is the issue. if I turn key to the on possiton fuel pressure jumps to 40psi but with-in 20-30 seconds is dropped to @ 15.

Litfters
3. adjusted the valves, had 3 or 4 callapsed lifters, cant afford to replace right now. I dont think its cost too much power or risking damage to motor, Im I right?

Mass air meter
4. I can get a lighting 90mm MAS, possible to wire these to fox 5.0s and what lbs injector are they set-up for?

Brakes
5. my brakes suck ass (more than normal, which is pretty crappy to begin with), pads are good, calpers are good, rotors good (drilled and slotted). Thinking its gotta be the power brake booster?

Slightly late, but welcome to the boards!

1. Dont see why it would be an issue.

2. Have you pulled codes? That pressure scenario is not unusual. The system bleeds off pressure by design. The FPR and check valve can both allow it.

4.You can wire up an LMAF but you'll need a way to get inside the EEC to tune for it.

5. Need more info. Has the fluid been flushed (you said it sat for a long time)?

Good luck.

3. You do know collapsed lifters can come apart and put small/mediem peices where you dont want them, right?
