1.25 rockers on a stock engine...

[Doogie S]

Astromic,

fullnoise is right on the money. While you will see some increase in performance, you're biggest gains will be had from a 1600 cc engine.

Typically, the changes go something like this: New header exhaust lets more air out of the system, dual port heads and ratio rockers let more air into the system, and a 009 distributor to help ignite the fuel. Some fine tuning of your single carb may yield some performance gains as well, once you get the exhaust system in place. Typically, a set of dual Kardons are the ticket for a stock engine.

This is about as far as you can take it without ripping into the engine and enlarging the displacement.

Hope this helps.
