Im collecting parts for the swap and am a bit confused as to how the engine, C4 and starter come together.
Im not sure what C4 I have. I have a receipt from the PO that states that a reman C4 was installed by a local tranny shop. I crawled under the car and didnt see a tag anywhere on the transmission.
Lacking a tag, how do I determine what tranny I have?
I have a RF-D7DP-7976-AA bell. I think thats for 78-80 250 and 302, case fill.
Does this bell use a 157 or 164 tooth flexplate?
RockAuto lists both 157 tooth - 13.3" diameter flex plates and 164 tooth - 14.23 diameter flexplates for 250 sixes.
Im hoping to use the 164 tooth flexplate so I can use a 3.8 starter.
