Critique/suggestions on 273 engine build

I was originally going to get a 318 and build it. I just thought that since this engine has a fairly fresh rebuild, I won't have to worry about rebuilding the bottom end. If I get a 318 (or anything else), chances are, I'll have to start from scratch and do a full rebuild, unless I find someone selling one that's already rebuilt for a decent price. I'm looking to get about 9.5:1 or 10:1 compression. I have an 8 3/4 with 3.23 gears (one legged) that I'm going to put in it. I know I'd need lower gears to get any kind of torque to the ground, but I'm just going for a mild street machine for now. The headers are the most expensive part of what I want to do. Cam, springs, locks, seals cost about $225, flat top pistons are around $200-250, the headwork would probably be around $300-400, new carb around $500, but I'm sure I could find a used one for a lot less, then the Headers-TTI at around $700, or spitfire for a lot less (but would require converting to manual steering which is more $$).
I would RATHER have a 340 or 360 with a lot more power than I'm going for here, but I've decided to work with what I've got due to cost.

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:
