80's 360 in a 60's mopar

This is what I learned about hopping up smog motors. A thin head gasket is probably already there and if not the gain is nothing to talk about. Just install a dual plane for the street, a 750 square bore carb is as big as you want to go, mild cam durations work best. No head work needed unless the spring seat needs machining. The rest of the drive train is a simple shift kit and stall converter if needed and a rear gear change to suite the cam and intended purpose of the build.

Re sell everything that your not using to roll over into new parts to simply help the project and wallet. Learn how to rebuild and tune and install your own stuff and you will be waaaaay ahead of the curve.

And lastly, just enjoy! That's what I learned in my youth in trying to get somewhere in hot rodding cars with a light wallet. Just enjoy it all.

If you take the time to look at cams specs and where the manufacturer says they will perform in, there is no need to retard or advance the cam. The K.I.S.S. Method works great!
