I am building a TVR with a 5.0L out of a 93 mustang. I need to go with a set of underdrive pullys to get the clearance i need. I can't find the diameters listed on the internet for any of the underdrive crank pullys except the March performance, I was wondering if anyone knew the diameter of any of the other companys that make underdrive pully kits?
thanks for the help

Depends how close you need the measurement. Mine are asp.racing/Steeda and the lower pulley measures around 4 inches vs the stock about 7 inches diameter.
