I'm running a high rise and the intake/carbs/air cleaners JUST barely fit. I've tried a couple of things. Raising or lowering the rear trans mount can work all right, pinion angles change very little. But the difference in that rear carb hieght sure changes! Depending on the trans (top loader or TKO600, I've run both) I had to ADD hieght to the top loader and REMOVE hieght for the TKO.

Where it really gets tricky is the side pipe exit through the hole in the body!! With engine torque the headers can rub the lower portion, so you might have to consider solid engine mounts.

Try this: Simply unbolt the trans mount or remove it for more clearance and useing a floor jack move the rear of the trans up or down to see what you get. Thats what I did, and then took some measurments for the trans mount "thick sleeve of aluminum" between the trans and the mount. Or, remove the "shim" or modify the trans mount to get it lower (which I had to do for the TKO). I never messed with the motor mounts at all.

From what I've seen, trans mounts are not always the exact same hieght, it depends on who made it and where you got it, I guess...
