So, getting ready to send out the 340 for rebuild, its the original motor for my 73 Roadrunner, and i want to get a bit more performance.
I dont want to go to crazy as it will be driven on the street and the highway. Its an automatic car with 3.55 gears. I am also thinking about bumping up the compression from 8.5 to 1 to 9 to 1. Thoughts?
what cams should i consider with 8.5 or 9 to 1 compression?
