I just recently stumbled onto my dream car a 1972 dodge demon. I have a 340 I had built a while back that has ported X heads with larger intake and exhaust valves. It has the LD340 intake which is fine for now. On the Dyno is was 430hp with a basically stock street camshaft. I'm looking to increase that to more of a strip street cam that will flow a lot more, as well as change it from solider lifter to hydraulic. The car will be driven to town and around, but I would like max high RPM power and obviously that lopey sound as long as it doesn't die at the stop lights as well as have zero vacuum pressure. Also should I look into replacing the LD340 intake or is that a good start? Any suggestions are greatly appreciated.

Keep the LD340 It is a very good manifold
If it has solid lifters ? You need to check and find out what cam it has. ALL factory cams are hydraulic

This is the cam that I was looking into. I wont know what cam is currently in it until I pull the engine apart for a reseal and new paint. Also it will be a 4 speed car, with a dana 60 currently has 5.13 gears. Most likely will run 4.56's in the end, taking suggestions on that as well thanks all.
