Ok I have an 85 Dodge diplomat salon 4 door that im making into a sleeper. I want to take the 318 i have an bore it .40 over an make it a 390 stroker. I've read that it is possible to make 360 heads flow better than the stock 340 x heads heres the link http://www.moparmusclemagazine.com/techa...ng/viewall.html So i was considering doing the exact same thing an putting them on the 390 stroker. As for a cam and intake im not sure. I want the car to be streetable but also have a hefty amount of power. The car is planned to be a sleeper an intended to blow the doors off of teenage kids who think they are on top of the world. I also have a 650 holley double pumper laying around. Would that be to much depending on the cam an intake? Does anyone have experience with this kind of motor build an have advice for cam an intake based on what iv said? Please any advice is amazing!!!
