What kind of car did you swap yours into? Did you have any issues running the 3 speed trans with an OBD2 setup? Im going OBD1 in mine. Now that you mention it, I do recall reading somewhere that the casting ribs had to be ground off in a few places
1969 Nova 454/M21/3.31 Mild mid-11 second weekend cruiser
1994 F150 XLT Super Cab 2WD 5.0/4R70W/3.55 (Daily driver)
