Welcome from Georgia! Nice Duster. I built a 318 for my brother's '66 Barracuda a long time ago when we were in our 20's. His 318 could ALMOST run with my 340! I don't think you will end up with 500 HP unless you have deep pockets. However, that motor is very peppy with the right stuff in it. Don't over cam it. Don't use a single plane intake manifold. What ever you do, buy some headers. The drivers side exhaust manifold on a V-8 A body car has to swoop around the steering rod and it's VERY restrictive!! If you have too much cam and the wrong intake and keep the stock exhaust manifolds it will be a real pig. Hopefully this puts you in the right direction. Feel free to ask questions anytime!
