I was thinking about one of them Jet rebuilt quads as well, if its in the budget after the rebuild I will probably go that route. I thought the 4:10 gears would be about right with the 700's over drive. with my current tire size it should work out to 2100 rpm or so at 65. I tore into the 283 block today and discovered it had a crack between the freeze plugs, so I guess thats that. I got my heads back that I am going to use. they are 462 casting old school fuelly heads. Thay now have new 1.94/ 1.6 valves guides and hard seats. I will add the springs whenever I settle on a cam. Summit racing has a few house grinds that may work out. so I guess its between the 350 and 327 at this point. I already have a set of forged .30 pistons for a 350 but the compression would be near 9.5 so that may be to high for a heavy truck. Im all ears guys!
