Roller valvetrain in Ford 460
I'm working on a 1978 ford 460 engine. My idea and plan is to make as efficient an engine as possible, while getting the most bang for my buck. I'm not too concerned about horsepower; this is going in a car weighting nearly 6,000lbs, so it's not going to be raced, only cruised in both on and off the highway. I don't have all the money in the world, but I am willing to put money into things that'll do the most.
I was planning on changing to a roller cam and rockers, but I've heard that a roller cam and rockers don't really work well in these engines and wouldn't be worth the money for what I want to accomplish. Is this true?
I do plan on getting fuel injection on this engine; from what I understand and have read I can use a late model top end- heads, intake, exhaust, etc- and be ok.
