Here is the skinny on my engine: I yanked it from a 78 Jeep pickup, presure washed out the inside of the block (replaced the freeze plugs), put in a new edlebrock performer cam, lifters, timing set, intake, 650 carb (with off road needles and seat kit), new push rods, stock style rocker arms, new timing chain cover, new oil pump gears, new fuel pump, and other little odds and ends. I am using the stock CJ Motorcraft ignition system (with an MSD Blaster 2 coil). I am also using a new stock style replacement radiator (think this will hold up to the heat of a 401??). I dropped it in my jeep, primed the oil pump and fired it up, it ran a little rough and while I was breaking in the cam, I heard a knock start :evil: , so I cut it off and here I am!!
So now I am at the point where I need to due a complete rebuild of my 401 and need some advise on parts selection. I want to run a 9.5:1 compression ratio, so who makes a good piston? I don't neccisarily need forged pistons, but I want something that will hold up to my heavy right foot. Of course, price is always being considered as I can only throw about $300 a month at this project. I am not looking to spend $800 on pistons if I can get away without spending that much.
Also, what all should I have done to the heads when I rebuild? Any easy mods I can do at home to free up some HP? I am also considering doing some of the oiling upgrades as well. I have had a few 304's die on my due to oiling problems. Finally, does anyone know of a good source for good gasket kits or for AMC parts in general?
Thanks guys!!
Jack
PS-I'll take pics of the rebuild if you want!
