My 82 fbird has the Iron Duke with the Th200 and its slipping horribly, I know I can pay for a rebuild but for the price I kinda want to put something stronger behind the duke?

Summit down the street from me sales there reman 350s for nothing with warrenty but I have no idea about bolt patterns?

Thanks for any info

 

If memory serves, that thing has the BOP pattern. So a BOP 350 should fit without much effort.

Post a pic of the BH from the front, where it would meet the engine if installed, and we can maybe identify the bolt pattern.

 

Depends on year. Early Duke's had an SBC pattern, later ones had the 60* Metric pattern.

 

If my current transmission pan says metric on it would that clarify the 60* metric pattern?

and sofakingdom you mean take a pic of the block with the transmission off showing the flywheel?

 

No. The 200, 200-4R and 700-R4 had that on the pan, regardless of bellhousing pattern and each came with at least 2 different patterns.

by process of elimination, google "chevrolet 2.5 bellhousing" and you'll know pretty quickly what the 60deg. engine bolt pattern looks like and can compare to yours, thus answering your question.

 

Since the trans is dead and you therefore already have it out, take a pic of it from the front, where it bolts to the block. Pretty easy to identify the pattern.

 

I dont have the trans out it will be once i can get it to a friends house with a car lift so much better than do it at my place i dont have flat ground anywhere

and aaron goin with this source http://en.wikipedia.org/wiki/List_of...using_patterns
my starter being located on the left side if viewed from the fly wheel it looks like cv8

 

If it looks like the Chevy pattern then a Chevy trans should fit it.

Just gotta make sure which side the starter is on; driver's side, or pass side. Not sure what that other "left" stuff is saying.
