Stock 360 from a 1984 Dodge Pickup

If you replace the cam, you have to replace the valve springs. If you do the springs, you have to remove the exh valve rotators. On my '87 in my truck, I removed all the smog stuff, tapped/plugged the holes, stuck a windage tray in it, replaced the cam with an XE262 Comp, a new timing set, a set of Comp 901-16 springs, and put back the 318 Performer and Edelbrock 750 that came on it. I also put an earlier distributor in it so it had the vacuum and centrifical advances, and put a performance curve in it, and an MSD 6AL. You could duplicate that for about $1500 with all new parts and never take the heads off. It's been running in my truck for 5 years. I changed the oil a couple times and rebuilt the carb once... That's been it for maintenance.
