Mopar 273-4bbl Combo

James L Miller · 11-17-2016, 01:31 AM

I bought a 1966 Dodge Dart off a local Stock/SS racer in the DFW area. It's pretty much just a roller at this point, but it has a cage already in it. My plan is to run it in Stock, natural K/SA at 13.47 #/HP, probably drop down to L/SA. So far, just have a couple of blocks, cranks, picked up some 920 heads at a local swap meet, bought an LD4B and a 1967 273 AFB off Terry Dye. I made a post over on Moparts about valve selection that works in these heads, and some body suggested I put a post over here. So, if anyone has any info they are willing to divulge (buy this, don't buy that, you're a loon for running a Mopar, etc.), please post or send me a PM. Thanks.

I used to run a 340 Mopar. When I saw the ports on a 273 I couldn't believe how small they are. If I were you I do some serious research before you commit and waste money on a weak combo. In Stock Elim., don't see it working out very well.

The Bushmakers out in D6 seem to have figured it out...Angela runs K most of the time and is up on the sheet consistently.

Jim you are correct. Angela's car runs very well. It is a 65 Valiant 2dr. sedan

Was the Chrysler Marine 340-4 Super Bee engine with the 4bbl steel manifold, the same as that motor. We have one laying around somewhere.

may i ask, who did your 2 barrel carb?
