If you want floor start, you simply need a nice inline 6, 235 or 261. All V8's were electrically actuated only.
Not saying that with a bunch of fab work that it will not be possible though.
What you could do, is fab a bracket that mounts to the existing bellhouse to engine bolt locations use washers to space it and longer bolts etc., it would allow to use or mimic the 6 cylinder bracket. And do what cletis said.
No need to mod or ruin the good factory truck bellhousing.


Kicking self for selling off my Taskforce trucks.
Still looking for an LCF or conventional big bolt in decent shape.
