Another opinion question

Adam may be on to something there too. A later model 360 (5.9L Magnum) will have provisions for a roller cam, electric fuel pump, and the Magnum heads..You also have 1.6 rockers. I'd look at that route, if I had to buy a core, I'd do that. You can always upgrade later to Commando heads. In terms of ET, what exactly do you want to run...68 makes a good point there.
