Boosts for a 85 L69
Hey there, Just purchased my 85 Trans Am last week, It has the L69 305 H.O. I am basically wondering what I can do to it to give it that extra boost. So far I replaced the 10" by 2" air filter with a 14" by 3" and I put hi flow cats on with a more free flowing muffler. What else would you suggest?
I am also planning to pull it out and rebuild it this winter, so things like new cylinder heads are a possibility.
