i was planing to make a mod sled out of a 75 sst440 f/a i have found i can get parts for this thing, but it is a mess of a few sleds. it has a cat clutch on it why i don't know. the hood was choped up and has a hole on the right side on top. under the hood there is a big fiber glassed tube witch is connected to the hole in the hood. no air box on this thing. and i am not sure if it has been ported or not. i ran a few of the parts in the clutching and they are race pices. the weights on the cam arms are 29g and last time i had it running it would rev to 10,000 rpm, what do i have here a pos that was piced together or did some one actually set this thing up this way. i would post picks but i dont know how.
