I am looking at the possability of puting a 700R4 transmition in my 66F100 with a 352FE ( rebuilt 17k ago and running strong ) I know It's not ford but it is overdrive and automatic. I have found adaptor kits at a place called Performance Automotive, They show 2 kits one for FE motors 352, 360, 390, 406, 410, 427, 428, And one for FE390, The first kit showes 2 differant adaptor plates with differant hole patterns, The second only has 1 plate, the differance in price is $300.00 minus the price of a mopar starter. My question is this, Why the differance in adapto plates? I understood the 352 - 390 were the same are the 406 -428 the differance ?


Thanks in advance

 

My "guess" is that one of those plates you are seeing is not for the FE engine. The top one looks to be for a small block aplication, but I would need to know the spacing of the two top bolts for the hat style bell housing. Other than that, the cost of the starter/flexplate/bolts are probably what makes up your $300 difference. You would need to use the specific flex plate for your motor as the balancing characteristics are different from the 390 and smaller or the >390 motors.

Just my $.02 --Mike

 

The 428 and 410 are the only one that are external balanced, the rest are internal balanced, including the 427. Your 352 is internally balanced.

I'm not sure how long a 700R4 will last behind a 352; they were built for anemic chebby SB motors.

 

Jav, if you are looking for an automatic and would consider using a Ford, ( why not ? ) you could check out Lentech transmissions. They offer a kit for putting a Ford AOD behind a FE engine, and their AODs are plenty beefy too. DF, @ his Dad's house
