Just for reference, here is the fender tag for the car. Not sure if anyone cares.
Look em up and compare to real gross HP numbers for a 273-2 and a 318-2. Like a poster said, we are comparing motors with the same go fast parts, only thing different is the bore. Now let's compare a 10:1 273-4 to a hypothetical 10:1 318-4 (cheaper to build new than a 273-4). There will be no comparison with +20%, or 45 more cubes. I stated there is nothing a 273 can do that a 318 can't do better. Sure the 273-4 has +5 hp but when will it catch up to a 80 ft/lb torque advantage? Gearing is not part of the comparison. Post up what you find, it will be interesting for the thread.
It will cost the same to build a 340 as 273 and not limited by early heads/intake bolt. Schumaker makes a kit with motor mts/ insulators/bolts to make the change- I have a set NIB I can sell for $100- check there website for now price-Long time Mopar fan and previous member to this forum. I am just getting back into it now because I have the option to purchase two 1965 Barracudas. The motors are out of them already from previous owner and I believe 1 was a 273 Commando car. Did Mopar do #'s matching with car and engine in 1965? I am just wondering if I should put back in the original 273 (not sure it actually is) to keep original or should I go with a 318/340 right off the bat if I am looking to build the engine up down the road? Not looking to do anything crazy with power, but just don't want to get my butt handed to me by my Dad's '64 Barracuda that has a 318.
Any suggestions/feedback would be greatly appreciated!
OK, finally was able to take possession of the car and actually got to talk to someone who knew about it when it was purchased. Car was going to be a Drag car build and didn't come with an engine. The seller threw in a 273/2 with the deal, but I don't think they made a 273/2 Commando? Now knowing that the engine isn't the 273/4 Commando that I thought it was, I am thinking I am better off going with a 318, versus trying to get the 273/2 built up. Thoughts?
