OK guys, I found a nice donor 235 from a 56 truck complete with transmission and foot starter. I want to put this into my 49 car. Still trying to decide if I want to keep it 3 OTT or changes trans. I have read alot of posts, but still a little confused about the best way to swap this in to my 49. I apologize if I ramble, just not sure which direction to go here. I bought this engine from the nephew of the original owner, so I feel good about it's history and just looking in the breather hole it looks pretty clean and not gunked up. He said it has just under 90K on it and was running. Should I pull it apart or run it? I think it is still in good running condition. But since I am gonna have the car completely torn apart I am inclined to do something to keep me from pulling it out later for a rebuild. Not sure what typical life expectancy was on these engines. I would like to put on a dual carb intake and make the 235 as peppy as possible (cam change??). I know I will have to change front plate or drill holes to mount in 49. I have an AX15 trans that I was gonna use in a 69 truck - so also considering a Novak plate to adapt it to the 6. Would I use the 56 bellhousing if I did that?? Or can I use the 56 bell and 3 speed that is here and hook it up to the 49 linkage? I will be converting to an open driveline, need to find a rear and figure out what rear gear will be best with the 235 to keep it running in it's power range. I have read posts that seem to indicate the 235 won't be effective to run 70 on interstate even with an OD trans. If that is true, is the cost/trouble involved worth swapping to a 5 speed versus using the 3OTT. I do like the 3OTT feel/nostalgia, and my car has a cool art-deco kinda tube setup on top of the column for the shifter too. Can the 235 and 3OTT run 65-70 more comfortably with the rear end change - and if so what ratio would allow that while still having enough gear for the 235 powerband?
