200 4R - which bell housing is best ?

[81cutlass]

I have owned 3 200r4's and have never seen one that is not dual pattern.

Th350 came bop or chev and th350c had dual pattern.

In my (hopeful) future project parts stash I have a uni bell TH200-4R that was in my parts car '86 Monte w/ a LG4.

We have 2 and both are the same pattern as posted 565's pic. I thought all were like that as 81cutlass mentioned.

neither one is any better get which ever one fits your motor

Not necessarily better but I would rather have the option to run either a BOP or Chevy than be limited later if I decide I want to go a different route and not need an adapter to do it.

Thanks - I got my trans today. Its a core and it will be rebuilt as new with some upgrades. A few weeks based on his schedule and hopefully in a month I'll have a new trans with overdrive. I'll save the current trans pulled from an '84 monte carlo ( TH350) incase some one wants one in the future for a restore. Making progress.

The TH350 in my 70S was dual pattern.

i have two 200-4r that came out of olds powered cars and one that came from a monte ss. all are dual pattern.

From my own experiences, only the early 200 4r transmissions had BOP or Chevrolet only bell housings. In all my years around these cars I have only seen one that wasn't dual pattern and it was a BOP pattern All the later ones had the dual pattern. I personally would be hesitant to start with one that was single pattern knowing that it is an early one and does not have a lot of the factory upgrades that were made over the years.

All 2004rs have the dual pattern and No removable tailshaft. they never made a chevy bolt pattern only , or a BOP only pattern.
