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

That is a VERY good combo. One of my good friends had to run them at Vegas in class, and his car is by no means a donkey. He told me he had NOTHING for them. Bushmaker has done this for a year or 2, he knows whats up.

Is Matt the guy with the white Valiant that runs in SS/K? I think I saw him a number of years ago at Ennis. Not sure how he would like me calling him for info when I'm having a friend/machinist/engine builder in Tampa build my stuff. I guess the worst he can say is to bugger off.

I was sort of hoping to build a dime rocket, or at least a quarter rocket. It does look like Bushmaker's got it figured out. Yes, the ports are tiny, about the size of 302 Ford heads (at least the 1960s stuff I've seen). I thought it would be a good entry into Stock. It doesn't need to fly and compete with the CJs, COPOs and DPs. It would be nice to qualify for divisionals and the national event at Ennis and maybe Houston or the next nearest track.

Thanks to all for your responses and information.
