Re: Need help swapping in TH400
I put a 454/th400 in my 72 4x4 blazer. I moved the trans/transfercase mount rearward 1 inch. this put the transfercase shift lever back in the stock location. I also moved the engine crossmember forward the other 2" or 2 1/4". This gave me plenty of room for an hei. If you want to run tall valve covers you may need to "massage " the firewall. I ran a 2wd bb fan shroud, and everything looks like it was installed by the general himself. There is only one v8 frame mount crossmember, since no 4wd ever came with a bb.
