I am running a 347(238@.050 solid cam, 650dp rpm air gap etc, 337rwhp) with a 3550 tremec (3.27 1st gear and .8 5th) with 4.1's in a 68 mustang coupe with 235/60/14 wheels. My engine does not not make **** loads of power compared to alot of other engines out there.
I went to the drags and all it did was spin 1st, 2nd and half of 3rd. Not a good combination for drag racing. I think its an excellent set up for the street.
It spins up quick and cruises at 2500rpms at 70mph.
In 4th with 4.1's at 50mph it feels and sound like its in third. But I cant have it all.
My box is notchy but its not really a car for a quiet sunday drive so it does not realy matter.
My vote the TKO 600
