250 L-6, 3 on theTree. Do I swap for a 327 and a Four Speed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Listen. A muncie 4speed is a 1:1 4th gear. Meaning if you are screaming at 60mph with the 250 3 on the tree, which you are, you will be screaming just as loud with the muncie. No good. Either keep it as is, they are great for short trips, or go with an overdrive tranny, T5 for manual. IN FACT, the premier tranny for you is a 3spd overdrive unit. Basically your current tranny with OD. Tough to find, but if you come by one it would be cool, AND would allow you to keep your column shift.

My Vote: 3spd stays.
