Welcome to the forum. What do you mean by "make it better"? That's a pretty general statement. Is there an issue with misfiring, flooding, etc... Do you have dreams of going down the 1/4 mile in under 10 seconds?

Details, please.

While not knowing your exact needs "make it better", I'd say start with a 6-into-1 header, ceramic coated if you can afford it, stage 2 cam, 2 1/2" exhaust pipe and a turbo muffler or something similar, upgrade your ignition system with a "Pertronics" or "Mallory Unilite" or something like an E12-80 module ignition from a 79' 280ZX.

If you have a "Metal fan" toss it and go with the plastic clutch fan assembly.

Only use NGK Spark Plugs and wires. I speak from experience.

This is obviously just for starters. Every one has their own choice in products and services but I'm sure you'll find everything you need here. Just use the search function or start a thread and ask away. We live for this stuff!!

Welcome, and enjoy,

Dave.
