Re: TH400 under small hump floor
small block or inline, yes. That's how it woulda come from the factory.
With a big block, it woulda had a high hump. It'll fit if you have good cab mounts, but IMO, NOT a good idea. GM didn't throw the high hump on there just to do it. They did it for a reason. |

Re: TH400 under small hump floor
Go ahead and put the th400 under the low floor...it will clear just fine. If it didn't you can just cut the floor and bolt in a high tunnel, but I am sure it will clear with no problem. I run that setup with old cab mounts and no problem.

Re: TH400 under small hump floor
It will fit but as mentioned above the cab will be hotter because there isn't as much air flow, plus, make sure all your mounts are in good shape.

Re: TH400 under small hump floor
So a 71 long bed with a 402 and th400 has a high hump? Good thing I have not trashed the truck yet. Going to take that sucker out next time I go home. Almost trashed it last weekend. Good think i didnt.

Re: TH400 under small hump floor
going along these lines, I've got a 71 cab that had a 350/automatic stuffed under it, I was wondering if a 4speed on a 350 will work? (obviously cutting for the shifter, and with new body mounts) Or do I have to hack the whole tranny hump out and put a removable one in?

Re: TH400 under small hump floor
A NewProcess 4spd will require the high-hump,for sure.

Re: TH400 under small hump floor
