I've got a 1984 Dodge D150 with a 318 in it and I was curious what would be the best most affordable rout to go to squeeze some HP out of this engine. What I had in mind is to put a sock 340 cam in it with a four barrel intake/carb. What kind of heads should I run on it? Does what I have going so far a good start, and also how much HP can I get out of it from that I want to be around 300hp. Also if any knows what is the best transmission to run behind this engine?
