I am not really sick of the topic. I just got the difference between the two methods answered. Also there are several more threads on the topic. Oh yeah, Pennzoil air cooled 32:1, Coleman fuel (you missed that one), 95 extended pos Dodge B2500, if the ribs are cooked right you don't need no sauce except what your drinkin'. Uh lets see one Gateway I built up, 2000 vintage server that needed a way too expensive box to fit in and a beater Intel 3.06 home built. Exhaust - usually. Brand zenoah 20 and 26, dle 20 and 30 , Evolution 26 and a Fox 3.2. Lets really crank it up. I use camp fuel cause gasoline stinks.
