Bellhousing, RAD 4-speed to 305 Help.

[whisenand]

I want to use my original 4-speed out of my 75 coupe.Does anyone know which bellhousings will mate it to a V-8?

so you want to meet it with a chevy 305?........or did you mean 302/306?

if a 305 i have no clue. but if you have a 302, you just need to find a RAD 4 bell housing.

all 260, 289, 302, 351 based small blocks will accept the stock bell from a v-8 4-speed mustang II. keep in mind the v-8 4-speed bell is specific to mustang II.

there may be others that can be massaged but i am not aware of one. the t-5 bell would be an option only if you were going to a 5 speed.

someone can chime in to confirm but i believe the v-6 4-speed bell has a different bolt pattern.

Sorry, I meant 302. Any way to identify the correct bellhousing with a part number?

Do you have a v-8 rad transmission? I'm guessing since you said its out of a 75 that it is not. In any case the v-8 and 4/6 transmissions used a different input shaft and different gear ratios. The ratios would not stop you from using but the input shaft will.

I did not know the shaft was different. Thanks for the info, I guess it is back to the drawing board.

you can never go bad with a t-5!....i will be doing my conversion as soon as its warm!
WOOT!

 

[whisenand]

Will I need to shorten my driveshaft if I go T-5?

Yes, most likely. But that depends on you current dirvetrain that is in the car now.
