Hump size Question
Just about to buy some ACC carpet...
I have a Canadian built C-10 that originally had a 307ci, with a manual tranny (three on the tree, not floor shift). I am thinking this is a small hump, correct? I did a search but didn't see a clear answer to my setup. Thanks!

Re: Hump size Question
high humps came in;
4X4 trucks 4 speed trucks Big blocks with TH400 or 4 speed GMC 1/2 ton V-6/TH400 trucks Anything else, would have a low hump. Small block with TH400 would have a low hump, many seem to think it'd have a high hump. |

Re: Hump size Question
Here you go. Examples of high and low. Low is welded to the floor (actually part of the floor) high hump is bolted to the floor.

Re: Hump size Question
400 would be a big block (402) so it's a high hump unless it is the one of VERY few that had a 3 speed manual in it.
