66 charger 318 upgrade questions...

Changing your cam and heads can make big difference in how your engine performs, but it's not a simple job. Every time I take on one of these upgrades, I end up spending a lot more time and money than I anticipated, mostly for all the might-as-well side quests that I keep adding ("I can't put these old valve covers back on the engine..." "these alternator wires look like garbage..." etc.), but sometimes it's because the aftermarket parts I bought don't go together very well.

If you just want to make some noise and have a little fun smoking the tires with your 318, you probably don't need new heads. I think the biggest bang for you buck would be to install headers and a good, free-flowing exhaust. That will give you boost in power and attitude and also help you make the most of what you have. After that, you might want to go for rear gears and maybe a bigger cam.

Back in the day we called them "Wide Block" 318's even though they weren't.
Both photo's are the same 63 Belvedere.
 
Nice looking car!!!! But it is also heavy. The best bang for the buck would be a 360 with a mild cam....it will add power everywhere.
 
If I was in his shoes I would adjust ny expectations and just enjoy the car the way it is. Could spend lots of money ona poly 318 and it still won't be a performance car. It possible, but not too comon.
That's probably the best advice, and I am the worst candidate to follow it. :rolleyes:
