The 200 is way too weak, forget about it. You can actually use the 350 mount but it's better to get a 400. YOU MUST be careful adjusting the TV cable, go to bow tie overdrives in Hesperia, they have a web site and advertise in all the mags. Steve there is truly fantastic. You also MUST use a lock up torque converter, otherwise it will overheat, something a 700 can't take. It is NOT a racing transmission, but can be lots of fun. I run a ZZ4 with a LT4 hot cam and 12 bolt 3:55, it will light them up through first and about 1/2 way thru 2nd. It'll cruise 70 @ 2,100. A great hot rod item.
