tranny choices
 

tranny nearing end and exploring options. 351w in 70 sport roof. what are diiferences between c-4 and c-6? any experience swapping to manual? or maybe just rebuild existing w/ shift kit.

Re: tranny choices
 

The c4 can be built to hold up, and weighs less than the c6. Theres also an aod swap. That gives you another gear. Lentech automatics aod street terminator is rated for 700 hp and runs about 3k. I`m looking into a auto to manual swap myself. I`m looking at 2500 from a Mustang restoration place to make it look oem. Sorry for the length, hope this helps

Thanks for your input, good luck w/ swap.
