Re: 1979 C30 Transmission Swap
I have a 4l80 (cable) behind the 454 in my cc dually it dropped the rpm to 2200 at 75mph (was 3300 at 70mph with t400) im happy with the trans as I don't tow or have it loaded its just used as a everyday driver.
im pretty sure the 4l80e has a bigger hole in the case for the wiring plug and no cable hole so don't think the valvebody will interchange |
