- 2nd hand extractors (no names, genies, whatever... i picked up a set of pacies for $120 for a mate)
- If he's not running a holley yet, he probably should be. 465ish seems to be ideal for 302's - overcarbing is bad... i found a 600 vac was too big for mine and caused bogging and general crappy running. Some say thermoquads are better, but no bastard can tune them, and getting parts is a bitch.
- If it's a factory black-block XD V8, it'll have electronic ignition, which is a good thing. If not, get a blue block-compatible factory electronic dizzy from a 351C ZH or XC.
- Get an open air filter. K&N or King Dragon washable element with a $15 supercheap special chrome lid.
- If you still want more, get a cam. They're a bitch to install with the engine in, but it's do-able. May require headwork for this though (better springs etc). Althogh a decent upgrade would simply be an XYish vintage pre-pollution cam.
- diff gear change will give it a kick in the arse. Don't know anything about XD's, but chances are it's a borgie with a ration of 2.73 or 2.92. If you don't do a lot of highway driving or have a toploader, a set of 3.5's will really wake it up.
Before you do all that, make sure the unit you have already is set up to perfection - you'd be surprised at the gains you find in stuff like
- new air filter
- plugs
- plug leads
- dizzy cap & rotor button
- fuel filters (mine picked up about 400 seat-of-the-pants horsepower from new filter and lines)
- oil and oil filter
- correct timing
- correct mixtures on whatever carb you have already.
Uhm... yeah. That's about it. Ultimately, the best thing you can do is just save for a rebuild with a 351 crank, like I did. It can be done relatively cheaply if you do it yourself. I just gave my mechanic lots of money and he did it for me. I'm stoked!
*note: I'm by no means an expert, but i did get a lot of experience for the 12 months or so i wrenched every last drop out of my 302. Listen to others on the forum, particularly dudes like Davis and StrokeXD etc... They know what they're on about.
