Default 1977 corvette performance

I have a 1977 Corvette with a L48 motor and an automatic. It has 80,000 miles on it. The performance is ok with a K&N air filter and a 1974 exhaust installed. I like the idea of keeping it stock but can I squeeze more performance from the car as it is?

If you are willing to change heads, cam, intake, etc., yes

MelWff is on track. If you want to keep it stock (intake, carb etc.) Get a copy of the tuning papers from Lars here on the forum. He also has some info available for your carb.

Follow his advice, and you'll be pretty amazed at the results.

I can't seem to find Lar's email address. Maybe someone else can post it up here? Lars will send you the papers you need.

Have fun!

Look up how to recurve your ignition. That will help.
The next big thing you can do is rebuild the carb via this book.

This will make a huge difference. I did mine on my 77 and it was a night and day difference.
