Quick question for you guys. I am getting ready to drop off my motor (440) at the machine shop to start getting it rebuilt for my Charger. I don't know what the exact internals will be yet. We will talk about that when I bring it there. His recommendation was a good set of forged pistons that will put us at around 9.25CR. Beyond that, we haven't talked specifics yet. My plan is that I just want a good low range torque motor for the street. I don't race, but like to get on it from time to time, so I want something that will perform well in that 1500 - 5000 rpm range. I want to maintain a decent amount of vacuum to run the headlights, AC controls, etc. Plus, I'm planning to put the factory AC back in the car. I am converting it to 4spd, and don't want to have to mess with header and clutch linkage interference like I did on my 4spd Cuda (400 4spd). I have a couple sets of HP manifolds, so I was thinking of going with them over headers. Not to mention, with all the other costs of rebuilding the car, it wouldn't hurt my feelings to avoid the extra cost of headers, custom Z-bars, or hydraulic clutches!! My question is this,... Can I get away with using the HP manifolds and still get good low end torque for the street. I know,.... everyone says manifolds don't flow as well, but I'm not building a hi-rpm race car. I just want something with some good grunt out of the hole. If so, ... Can someone recommend a good cam to go with this type of setup. I talked briefly to the engine guy. He's an old school engine builder around here with a great reputation. I will see what he recommends, but would also appreciate opinions from here to see how they match up. Please let me know your thoughts. Thanks!
