Right now I have an 80's motor and aod in my maverick. My previous motor was a 250 6 and c-4 transmission. The c-4 transmission will not fit my motor as it is noq. I was thinking that maybe the bellhousing off the aos would fit the c-4 and I could just bolt it in??? if anyone knows if there is any possibility of this working it would be greatly appreciated. thanks William
The 250 bellhousing is supposed to be the same as the 302 bellhousing, so it should fit. I ran into a problem a while back when I bought a tranny that I swore was behind a 250, but the bellhousing was too small for my 302. I assumed I was mistaken, or that was why the tranny wasn't bolted to the motor... Anyway, that is what I have always heard to be true.
tranny I pulled the what I think is 250 and tranny out of my car. But from what I understand the 80's syle motors have larger flywheels?? correct me if I am wrong, but do you think there is and chance that the bellhousing that I have on the aod will fit the c-4. thanks for any help William
The 250 and 302 take the same bellhousing. I pulled a 250 out of my 77 & put in a 302 and used the same C4. You probably have a C4 from a 170/200. They definately are smaller
Although the 250 and the 302 can use the same bellhousing this is only true when you have a 157 tooth flexplate. If you have a 164 tooth flexplate that works with the AOD and late model 302's then it will not fit into the 250 bellhousing. I ran into this problem when I put an 82 ho 302 into my maverick. I had too order a 50oz. flexplate with 157 teeth it's something that ford never actually made. You can get it from sumitt racing.
Bellhousings See if this may help, click on C4-5 bellhousing applications. http://mmerlinn.tripod.com
tranny help alright I must have the 164 tooth flyheel then. Last summer is when I pulled the 250 and c-4 transmission and I put the transmission in the yard leaving the dipstick tube open so that water could get in it. I went out yesterday and turned it over to see quite a bit of water come out of it. When I pulled it it shifted great ,but now I am a little weary. So do you guys think that this transmission would be worth buying a new flexplate and putting it in or do you think it wouldn't shift correctly. Sorry for the rambling just got off work and am a little tired thanks for any help William
I utilized the original C4 when I performed a 89 5.0 motor conversion. I took the original C4 flywheel down to my machinist & had it rebalanced to the 5.0 motor. Really, no biggy.
flywheel so you took your 250 flywheel off your six cylinder and had it machined??? what did you tell them to do make it 50oz weight??? thanks William
I took my original C4 flywheel & the original 5.0 flywheel down to my machinist & had him duplicate the balance of the 5.0 flywheel onto my C4 flywheel. My Maverick was an original 302 car to begin with. It shouldn't matter that your flywheel was from a 250-6, C4 to begin with. Hope this helps.
It's not the balance that William has a big problem with. It's the actual size of the flexplate that is different. He has 164 tooth flexplate that won't fit into the 250 bellhousing. But if finds a 157 tooth flexplate he can have it rebalanced to work with his motor like you did.
I guess I'm confused. So, he doesn't have the original 250-6 Flexplate? And wouldn't that be a 157 tooth type?
I'm not sure if the 250 flexplate will fit a 302, although it is a 157 tooth flexplate I have no idea what the balance is.
flywheel ok now I am beginning to see what you mean. I still have the 250 flywheel which is bolted to my 250 motor. Now if the flywheel that is bolted to my 250 has the same bolt pattern as the one that is on me 302 I can just take it to a machinest and have it "balanced". how much did this cost you??? I can get a flywheel out of summit for 105.00 thanks alot for any help William
