Re: 72 Chevy K20 Transmission Swap?

you cant swap in anything that wont require modifications that will have an extra gear. if you are willing to go to the trouble of dealing with the electronics, i think a 6L would be fantastic. there are also valve bodies available that will turn the 4L80 into a 6 speed. that would be cool. i have an older 4l80e in my garage that i hope to do that with for something...

as far as swapping the trans, the easiest path would be the 700r4. i recommend moving the t-case backwards as opposed to the engine forward. it requires a modification of the drivelines, but i think it is better than moving the engine forward.
