That is very interesting to know with it behind something that small.
Yep! I figure with the header and the tiny NASCAR Holley 390 4bbl, it MIGHT make 120 hp!! The car weighs 2300 lbs with me in it. I'm in the process of assembling a new engine displacing 174 cu. in. and hoping to produce between 200 and 250 hp. I have NO DOUBT that that same 700R4 will work splendidly behind it.
The transmission, incidentally, is a used one, straight out of an old pickup truck, converter and all!! I just changed the fluid and filter and put a new detent cable on it!!
