Ok here it goes. I wanted to stay AMC, so i put an AMC 360 in my 1990 Wrangler. However, its seems that the 360 is a bit slugish at takeoff. Everything on 360 new or rebuilt. Here's the setup: upgraded ignition using Ford 460 cap, rotor etc. including changing oil coil to TFI, havent added the springs in the mechanical advance yet. Planning to do so. Running a 600 cfm Holley 4160, performer eldebrock intake, summit cam(cant remember which one, right now, sure its a low end cam, nice lope though). The problem seems to be that it doesnt seem to have the zip at takeoff, kinda boggs till the rpms come up, then she starts to come alive. Ive tried resetting timing, anywhere from 8 to 12 degrees, not much if any change. Vac. at carb is about 10 goes up to
25 when motor goosed. I did notice that once I connect the vac. hose back up from carb to distributer, timing goes up to about 15 to 19 degrees. Im looking for suggestions on how to get a little zip at bottom. Only running 31's, stock driveline, 727 tranny w/np231 transfer case, nothing she shouldnt be able to spin over on dry pavement, but wont......not looking to burn rubber, thats not a Jeep thing for me, but would like the bottom zip....Thanks in advance for any helpful hints.- posted
