Lifetime MemberLots of little improvments add up in the end. The cost may end up high but it is like making smaller payments. Heads and a cam will be the next step for any real HP gains.
I rebuilt my motor and later changed the heads to 64cc Edelbrock RPMs. It increased my compression and made it posible to go to a bigger cam if I ever get to it. Runs to good now so "if it aint broke, don't fix it" is in play.

Yep - I have a 79 also. The biggest jump in power (at least in mid range and pulling hills - seat of the pants dyno) seemed to come from recurving the original distributor. Then I went with the GM ZZ4 manifold and Holley 7150 carb. Added a billet MSD distributor and true dual exhausts. Now it feels quick and capable. Finally it moves as well as it corners and stops.
These are great cars. Mine was also a bit of a basket case and I am doing it on the "installment" program (I am paying for whatever I install).
Since I didn't learn from the experience with this car, I picked up another well used Corvette - a 1986 C4. I'll have to discuss it in a different forum however.

Hey Sfindlan,
It IS fun to have it running good!
However, it like a disease --- right???
Now that it goze faster, the sloppy old front end is begging for some much needed attention ( among other fixes that will have to be ignored for the time being).
Ahh well, I guess if we were ever done it might get old.
And you're right, "These are great cars."
P.S. Good luck with that other car that we can't talk about.
