| Dave,to answer your question about the externally ribbed bell it is a truck unit .58-62 pass cars useda bell that was smooth externally and had a deep starter pocket and will not accept an 11.5 or larger clutch 63-64 pass cars used a smooth bell with a C3AA casting # which also had a deep starter pocket but apparently will accept a large clutch because that is the bell 427s used and they supposedly had an 11.5 clutch.65 and later full sized pass cars used a C5AA bell that was smooth externally had the shallow starter pocket and would accept the large clutch and also has a boss cast into the side of it to accept the engine side equalizer shaft pivot needed for forward placement of the engine used in 65 and later full sized cars.66 and later unibody cars ie. fairlane, mustang and their cousins used a C6OA bell that is smooth externally and has the shallow starter pocket and accepts the large clutch and looks identical to the C5AA bell with the exception that the boss cast into the side of it is finished at an angle with no hole drilled or tapped.That pretty much covers them with a common theme that none of them are ribbed externally and they are all meant to be used with big block and y block specific input shaft length so to sum it up either the C5AA or the C6OA bells will work for you though the C5AA bell may require the side boss to be trimmed.To be safe it may be prudent for you to bite the bullet and change the bell to ensure proper pilot engagement.Out of curiosity what clutch fork are you using with the big input tranny? |
