best bang for your buck is nitrous, hands down. But nitrous is only good for 10 1/4 mile runs if you have a 10lb pound, and nitrous is a pain to refill. If you want a blower setup, you are looking at 2000-$4000 depending on the setup, but even more if you want to rebuild the block with forged internals. If you don't want to spend more than 1000, I would just spray a 75 wet shot and call it a day.

I appreciate the help. Not trying to offend anyone. Heres a list of what Ive done.

Custom exhaust- Dual Magnaflows
Custom Cold Air Intake
New plugs and plug wires
Advanced timing to 12
Coil
gapped plugs to .055
royal purple in diff, trans, and engine
seafoamed
Electric Fans
Hooker Headers
High flow magnaflow cat converter

Runs great, or better than it ever has, but it is still slow

I like the Idea of new heads, if I got some new heads what would I need to change in the rest of the engine to compensate (just injectors and fuel pump right.? I can get a set of heads that will blow stock heads away for $800 on ebay. I wouldnt need forged internals right?

No offense taken. I hope I don't offend you either but,...... You still have a lot you can do before you break open the engine.

You need to get your timing up to 14 or 16 degrees (may require a super hot coil and very low resistance wires and side gapped plugs)

Underdrive pulleys

BBK Throttle body

180 degree thermostat

Electric Fans

Davis Unified Ignition- Dyna Module

Each of those I mentioned is good for 8-10 horsepower. Keep in mind, it's the synergy of all the parts that make the difference. When manufacturers quote estimated horsepower gains, they are referring to a completely stock engine. Adding to a modified engine (no matter how slight) will normally net a larger gain. You can easily pick up an additional 50-60 horsepower by doing what I listed above. It could be more because you already have a good foundation. Of course, you could always change the gears in the rear from your 3.55's to 3.73's or 4.10's ( I went with 4.10's) if you want to really "feel" whatever power your engine is making. (I went from 3.08 regular axle to 4.10 limited slip, WOW what a difference!)

Good luck!

Good Luck with your project too, i will be watching, and thanks for the feedback.

Will that stuff add more hp even when I dont have a mass air flow sensor?

Yup! I've heard many, many times just getting rid of the stupid mechanical fan can net about 15 hp! Most everyone on this forum who has done the e-fan upgrade has noticed ample difference. Underdrive pulleys are an easy bolt on for 8-10 hp, thermostat doesn't net a hp difference but, every engine runs better cooler, the Davis Unified Ignition module is an old, tried and true 5.0 Mustang trick to net you about 8-10 hp because it increases the dwell on the coil (it makes the coil charge longer so you get a bigger spark) Just keep in mind, it's the synergy of ALL the parts working together.
