273 or 225?
My last 273 car was a 65 Barracuda fastback car I traded a buddy out of. Original 273 roller car, engine half apart, it had a 8 3/4 rear and came with a console auto (I hate the darn cable stuff!). All there but we had to rob a back glass out of one of his parts cars.Another PO had sanded it to bare metal and let it sit outside 6-8months but that is another story! I built it all back with the original engine/trans and did body and interior etc. and sold it in 2017 when we moved to Tx. I love the little 273 in a light car. Cool little engine. They dress up nice! 10:1 compression beats 8:1. Solid lifters. motor Are they as fast out of the box as a 340? No. But... the 340 did not come in the 66 Dart any more than a LS came in a 66 Dart!!!! But I degress.
I would get that parts car as cheap as possible. I am a sucker for a good parts car.
I would NOT use the darn cable shift. Just me. I have had too many. I would use the 65-6 floor shift. I would also understand the most driveshaft shops will notwork on that trunnion deal! My last conversion DS a couple years ago in m 64 Savoy cost me $500 and 2 trips to the shop. It all adds up.
Remember, unless an engine at least runs, it is a core. After the core goes to the machine shop, washed and checked, then you know what you have. If bad and you paid the price for a core and it has enough usuable and/or salable parts, it all works out in the end for the hobbiest that intends to stay in the hobby with more projects. If you aren't gonna be that guy find a good running enough motor THAT you can hear run and check out.
What was the question??? :thumbsup: :BangHead: :poke: :steering:
