BB onto 2wd
I'm getting ready to put in my BB with T-400 trans in my Blazer. Do I need to put in a high hump or will my low hump work?

Re: BB onto 2wd
The high hump is for the 400 trans

Re: BB onto 2wd
Since the engine is a big block, yes, you should use the high hump. On the piuckups, ppl get away with low humps and big block/TH400 combos all the time, but no tellin on a blazer. (we are talkin 2 wheel drive yes?)

Yes. The TH350 in it now was just rebuilt last year. I might leave it in until I have the TH400 rebuilt. Now I just have to get rid of the rest of the truck it came in

Re: BB onto 2wd
I think generally the rule of thumb is to have the high hump but you can get away with it if you have new cab mounts or well body mounts for the blazer

My 69 GMC has a factory turbo 400 and it is low hump with a fair amount of room. You'll probably be ok
