Suggestions; 69Z 302 Engine Rebuild

[1966L72]

I was adjusting my valves yesterday and noticed an intake stud starting to pull out of the head. Instead of just having the head redone I decided its time to go through the motor and freshen it up. Any suggestions to improve the low end performance to have a little more fun on the street ? I want to keep the original 4053 carb, 480 distributor and original valve covers in place... thanks

A 350ci type stoker kit, will substantially increase your torque and fun factor on the street.

Does the car have factory exhaust manifolds or headers?

If you were to slap a set of headers on that 302 it would make a surprising difference and be much more drivable on the street. In addition it's gonna sound incredible too!

Give Jerry MacNeish a call, he rebuilds tons of DZ's and they make ton of power and look and act stock!

He is at Camaro High Performance.

Bart is right, headers (and a free-flowing exhaust system aft) will open the door for significant power improvement, esp. since they allow you to step away from the OE cam should you be so inclined. If you plan on staying with the factory manifolds, stick with the GM cam as it's been proven time and time again to work best with them. Quality machine work during the rebuild can also make a noteable difference. A little port work on the heads can pay off quite nicely if you're not against the idea.

Aside from that, stick with the tuning basics re: jetting, timing, lash, etc.
