Both of those transmssions were built by a guy I know that builds "only" race 200's, the 3 speed version. They both have trans. brakes in them also. I know they'll hold up.
As for Art Carr, I may give one of his a try later down the road a piece...or if the stock one I have breaks..! Though I have ordered a bunch of goodies from Carr last week for this car.
Scott (Scott McClay Engineering) started building long before Art Carr (or anyone else, at least on the West Coast) started his 200's, though just for own dragster. He's got (3spd.) 200's in 8 sec., NHRA Super Stockers.
The Buick Grand National transmissions were originally a bit different inside than the run of the mill 200-4R's...but yea, the East Coast guys flog'em pretty good in their Buicks.
