you guys may not know but there is a mopar 904 tranny that bolts up to a chevy 350----these trannys were specd into postal jeeps powered by an iron duke 4 cylinder---then were made famous by Butch Brooks of loveland colorado who took these 904's filled them with 998/999 internals and sold them to offroad jeep racing teams that were running those hot corvette motors---he told me that he sold probably 200 of them over the years---another thing about butch ---he is a living legend in the western US among the offroad racers and some drag racers---a couple years ago at the rock crawling world championship in moab his trannys placed 1st,2nd,3rd and 5th---he offered the 4th place guy with a manual a free rebuild anytime----butch is down to his last chev/904 core and doesnt think he will ever find another since they have been out of production so long....bob
