i've heard of duel systems alky/gas i'm looking to just use nos at sweet 16's or q-8's but be all motor on race days so might be something to look into with plumbing and space problems that seam to come with owning dragsters.now i'm leaning back to the hat setup. thinking i can always put a terminator on later in the year IF the hat(or maybe stack)injection isn't working out for me and i just love them.One thing about a dragster real easy to work on the drive train.also having trans specialties build me a nos specific torque conv. for my motor my n/a 9" conv. is set at 6200-6300 way to loose for nos i would think jeff
