Technical Who makes a C-4 to Y block adapter

My 55 Sunliner is set up for a C-4 and I think someone makes a adapter to put one behind a Y block but all I have found are ones for. AOD or GM.

 

I believe there are 2 styles. If the C4 you have has a removable bell there is one that replaces it and directly bolts to the Y. If it doesn’t there’s a different one.

 

Flat O products. Talk to Gene.
Mummert also sells the Flat O products kit but why order from him when you can go to the source.

 

I was going to use a 62 COM with a 67 MX? valve body but why add all that weight and then have to get another driveshaft.

 

X2 on Gene. Answered all my questions, and shipped quickly.

 

Will call soon

 

Just got off the phone and that is where I will be getting the adapter.

 

Don’t know what differential gear you have but my OT Ford with a AOD runs down the interstate at 2200 rpm and 65mph with 3.89 differential. If you already have C-4 never mind.

 

If your rear end is stock it will have a 3.31 if it was a Ford-O. Since the C4 starts out in low you can comfortably go to a higher ratio without any worries and have a lower rpm on highways and interstates. I went with a Ford 8.8 with 2.74’s and for me it’s great. Almost all of them have discs and many a posi. The rear end shop that built mine had a complete drum brake set up from a mid 80’s F150 which are the same 11” with a wider shoe. The stock E brake worked perfect with only enlarging the cable hole a few thousandths from metric to inch size.

 

It has 3.00 gears and found out about a ready to drop in 292 that I will be looking at saturday,looks like it could have a Y block this winter.
