If i understand right you installed the T56 without modifying the tunnel. is here a reason others have had to modify theirs?
a LONNGGGG motor, a 300. . . . . . . . Yup a 300 I6!!!! WITH dual webers, hot cam, shorty headers, polished ported head with 194/1.60 valves all good for 325hp and 425ft-lb or torque. I REALLY want to use the T56, but I may default to a TKO 500. I am going to have too see if the finished engine product can stay within the 450ft-lb limits of the T56. The "big block" 6 is a torque monster.
Im going to have to MAKE my engine mounts, I may get a little bit of play there. Not sure. Im replacing the floor pans and I dont want to completely fis the flow only to find the trans wont fit, BUt I dont want to buy a $2500 trans for a car that has rusty floors.
