Transmission Hump question

I have a 67 c10 with a 250ci engine and 3 on the tree. It has what I would consider a very low transmission hump. I am planning to do a V-8 swap (small block) with a 700R4 transmission. Will I have to cut the hump out and weld in a taller hump to accomodate the automatic, and if so, do any vendors sell new humps or will I have to cut one out of another truck? My
14 year old son and I am just getting started on this project and we want to begin collecting the necessary parts.

Re: Transmission Hump question

im pretty shure that to do the swap, you will not have to change the floor hump. i think the large hump is mainly for 4x4s. i would check with one of the old school guys here, this is a pretty common swap

Re: Transmission Hump question

I'm no expert yet but I believe that the "high hump" was used for 4 speeds & auto trannys, which probably includes most 4X4's.

Re: Transmission Hump question

4 speed trucks
4X4 trucks
big block trucks
and V6 automatic trucks in a 1/2 ton
Are the only ones that got high humps.
So a small block with an auto is fine.

Re: Transmission Hump question

I've done the swap, low hump cab. There isn't much clearance, but it does clear. When I did my 350 700R4 swap I put the motor in the "correct" v-8 position. Not sure if it would clear if it were in the I-6 position?
