How Fast On 120s? (E85)

[Ttype6]

I have 60's now so yes I know I need bigger ones but trying to decide on the size, I am thinking of a fast system with the flex fuel sensor, I have a 66 b.b. now would love to get the 6766 but a little at a time, I need to get it to hook up the way it is now, I am going to try a re-locator in the back and a friend has some Mickey Thompson radials I can try, Not trying to take your post just answering a question

Once you cure your traction problems,run E 85 and work on curing your new found traction problems.
