the chiltons i have only lists the 304,
finally got my 360 going in my cj5, it is .040 with howell tbi and a HEi dizzy plugs gapped at .45
anyway i have a slight off idle stumble that seems to get better the more i advance the timing, i am at 12 now and may try 15, so far i dont have any pinging so i guess i am in the clear what do you guys run your pretty much stock 360's at?
also what about altitude, does that effect anything with timing? i am at 5,300 ft above sea level.
