Hi guys, Looking to pic your brains a little on my on-going engine swap pains. I am working with a 56 Plymouth, that was origionally a 6 cyl car with the push ****on powerflite ******. and now re-building a 270 poly from a 56 dodge to replace it. I got an adapter plate for a v-8, thinking the bell housing would be the same. (wrong) So, I'm guessing I need a v-8 bell housing as well? This brings up my next question: I just reworked my torque converter and installed a new ring gear for the starter, will I need a new torque converter for the v-8 too? Sorry to go on and on, and I appreciate any help anyone can give me. Brad
If it physical fits and bolts up, then I would try it and see if it performs ok. Does the drive sleeve fit it ok? This may be a problem, if it does not, then the V8 converter may be needed. The Powerflite box may also need to be beefed up too. I would try the setup to see if it works well before changing the torque converter. The V8 bell housing will be needed.
Not sure what you are referring to as drive sleeve, I have 8 studs that come out of the front side of the converter that bolt to the crank. The hole pattern is the same and the outside ring on the converter fits both the 6 and 8 cyl the same crank flange the same. Thanks
The drive sleeve is hollow and goes between the converter and the transmission and connects the transmission input shaft to the converter.
The ******s are the same, you will need the bell & spacer plate and starter( 12 volt) from the v8. The 6 cyl. torque converter will have a higher stall speed, we used them in the early years behind the v8s. Lee
Hey Lee, Thanks for the help. My 6cyl is a 12 volt system. Is there a difference between a 56' 12 volt v8 or 6cyl starter? Brad
Yes there is a difference. If my memory serves me correctly there is a distinct difference between a 6 cyl and a v8 starter motor. The way the 6 bolts up is done with an odd shaped cast iron "head " that is different on the v8. Its mot the voltage difference that is involved here - its more the physical shape of the "drive" head
