Pat,

If your car is an original 340 HP, it would have had the 2.20 close ratio 4-speed. All 340 and 360 HP cars came that way in 63. It would have been called M20 instead of M21 on any paperwork that you may have for the car but that was just to indicate "4-speed" and not ratio. The ratio was determined by the engine option.

All 63 4-speed cars, regardless of early/late Borg Warner/Muncie, had the small diameter front bearing retainer and 421 clutch housing.

THANKS FOR THE REPLY, SO WHAT YOU ARE SAYING IS M 20 IS CORRECT BUT WHERE WAS THE CUT OFF BETWEEN THE BORG. WARNER ( M20 ) & MUNCIE ( M 20 ) 220 CLOSE RATIO. SERIAL # 12921 (BORG. WARNER OR MUNCIE ? ) RICK NCRS. MEMBER

(1) Turn off your caps lock! According to 'netiquete' the use of capitals is intended for emphasis. You're inadvertently YELLING at us in your posts which I don't think you intend to do....

(2) The issue of wide vs. close ratio regardless of transmission mfgr (Borg vs. Muncie) has to do with engine horsepower rating and nothing else.

(3) The change from Borg to Muncie is well documented in your copy of the 1963-64 NCRS Technical Information Manual & Judging Guide (available at the 'STORE' on this website). In the Chassis Section, Item 10, Transmission, you'll read:

"....An optional 4-speed transmission is available which is manufactured by Borg-Warner for most of 1963 production up to approximately VIN 1500, and by Muncie for the remainder of 1963 and all 1964 production...."

I believe that is up to 15000 vin, at least per my JG and the vin on various '63 T-10's I've seen

Yup, my typo--15,000 not 1,500.... *NM*
