Need A Recipe For A 273 Rebuild

I understand you want period correct engine so staying with the 273 is wise. Take in consideration of .. is the car going to be judged on original condition? ... is the car got all of the original parts? hub caps, radio, etc.. Now here comes the kicker .... for what you are going to spend on the 273 you could spend on a 360 and be farrrrr ahead of the game. It will be a difference of just a motor pushing the car down the road or throwing the car down the road. LOL!

I know you might want something just to cruise around in and that's it but you can still cruise around with a 360 AND have some horsepower IF you need it. Kind of like a ace in the hole.


I have had both. I bought my 67 cuda with a 273 and tried everything under the sun to get the car to "move". I tried 3 different cams, 2 sizes of carbs, heads, etc.. and it didn't do a bit of good. The motor was even bored .060 over! I knew that the short stroke motor was not a beast put I just wanted extra pep.

Then came the planned out 360. Bored .030, 10.7 compression, better heads, etc.. and it so much better. Longer stroke made a word of difference. You could put a plain old 360 in her and without the bells and whistles and it would be better than the 273. The motors look the same unless you tell someone.

Just trying to save you some money and time. I wasted alot of money trying things on the 273. Oh if you keep the lil 273 a good cam is the Summit cam with .441/.441 lift. I got the part number around here somewhere.
