Listen.... I was trying to be nice:toothy10: since you stated "I know everyone is going to say go with a 360" but I think everyone else has expalined.
I've tried the 273 route before as a power builder and yes the the motor came with the car. Click on my username go to my threads I created.. you will the plees for help on making power with a 273... everyone is right believe me ... don't sink another penny in that motor!!! I gave my entire 273 motor away!!
360s have longer stroke cranks...
Save your money while you still have it in your pockets...
I have a pretty mild 360 (compared to other members motors) and love it yes it was extra money I know... but I love it!
Here is what I think of the 273 :thebirdm:
