Hi Everyone! -
The quick question: What type of automatic overdrive transmission can I install in a 71 mustang with a 429 engine?
::thumb:: The details: It's a 71 convertible. I'm replacing the original 6 cylinder / C4 tranny / 8" 28 spline rear with ------> 429 SCJ (dyno shows 572 HP at 5000 rpm and 617 Ft-lbs at 4600 rpm) / 9" 31 spline rear with N-case, Trac-Lok, with any choice of gear ratio, and the choice of transmission still up in the air.
:chin: The quandary: No luck by looking at previous threads. I have all the "stuff" to make the switch, but haven't decided yet on a transmission. I have several spare C6 trannies that came with the Cobra Jet engines (R servo and iron tail housing) and can rebuild and install one of these. But I would rather go with an Automatic Overdrive because, like everyone else in the world, I like both good acceleration and high speeds, and I'm not keen on a manual OD tranny because I like to drink my coffee while I'm driving. Articles on this subject usually involve trucks and not passenger cars. Some authors suggest the original Ford AOD or the Ford E4OD, with the latter more often recommended because it's a beefier transmission. Other articles say the E4OD is too big to fit in a passenger car. I would rather not go with an overdrive kit for a C6 for various reasons.
:huh: The In-depth question: What's a Ford Lover to do? :thankyouyellow:
