Dart to 4spd Conversion
Currently accumulating parts to do the same thing to my '68 barracuda. In terms of actual modifications to the car, you have to...
- Cut your floor and weld in a 4-speed transmission hump (to make room for the shift linkages)
- Either machine out your crankshaft for a pilot bushing OR cut the trans input shaft and use a brewer's adapter pilot bushing
- New driveshaft/modify existing one
- swap out auto pedals for a factory 4-speed setup
- weld in mounts on chassis for Z-bar setup (if you are going with a factory mechanical clutch)
Thankfully, you can use the auto transmission crossmember, all you need is a different trans mount.
Parts-wise, you'll need:
- A833 4-speed
- V8 bellhousing w/ shift fork, pivot, and boot
- neutral balance 340 flywheel
- clutch pack
- shifter and shifter linkages
- 4-speed floor hump
- driveshaft
- 4-speed pedals
- Z-bar setup with linkages and bushings
- pilot bushing
plus some other stuff I am most likely forgetting.
Price varies, many people say it'll cost upwards of $2500, but I am trying to do as budget as possible. I got ahold of an A833OD for $250, and I've got the proper V8 bellhousing in the mail (300 + shipping). Since piecing together the factory clutch linkage setup sounds expensive and difficult, I'm retrofitting a "factory" hydraulic clutch setup from a 1965-1971 dodge truck for about $100. If you want to go this route, you'll have to figure out how to cut holes in your firewall and mount the clutch master cylinder.
