267 Chevy
 

Anyone ever run One of these in stock? Seems soft at 150hp

Possibly Philbrick from Ontario? R/SA Monza record holder?

Philbrick`s is a 262 v8....different animal........Lee Tuttle from Albany Ga. runs a 267 in his 80 Camaro....classed in U/SA

Would it work better in a Malibu? the engine was made from 79-81. Got one sitting here, haven't found pistons for it yet.

Re: 267 Chevy
 

Neat "Dime Rocket" combo! 81-82 would be the way to go. Just don't get carried away with it. Square bore and stroke, not a lot of compression and the front half of an 800 Q-Jet. Gonna have to build cylinder pressure with your cam choice and don't try to spin it too awful high. Camaro would be neat, 8.5 rear is easy and cheap. Malibu or Monte Carlo would need GN rear or aftermarket.

federal mogul did and should still have pistons,will be stock cast,maybe hypertec now.
any of piston companies could make forged versions if wanted and get add to approved list.
Federal Moguls should work fine.

Found a free 267 in the Dallas area on Craigslist. Real small valves and not much of a cam.

Re: 267 Chevy
 

1.375 exhausts. The dual jet throttle openings look way small, I will take a Q-Jet off the shelve and compare the primaries to the dual jet. Has anybody ever seen the specs on a stocker cam for a 267? Milder duration than a 305, I wonder how much more mild.

Re: 267 Chevy
 

One way to analyze the potential is to do a simple comparison based on NHRA hp rating divided by the displacement. Most 2bbl engines suffer from the same constraints of no airflow and mediocre camshafts, so the race potential of hp per cubic inch will be roughly in the same range. The 302 Ford engines come out with the best hp/disp factors using such a crude analysis. A few GM engines have a better hp/disp factor than the 267, but its factor of .56 hp/disp is not bad. Billy's 307 Nova at 168 hp has a hp/disp factor of .55, so you might use that as a comparison along with Lee Tuttle's car.

Re: 267 Chevy
 

I know that this is not an apples to apples comparison but take a look at how fast Ronnie Charnes has been able to go with 3/4ths of a 267 and it has a smaller intake valve!
A million years ago, Buick did a bunch of testing on it's then just re-released V-6 and came to the conclusion that the engine size and number of cylinders didn't matter when it came to carburetor size. It was the volume of each cylinder that mattered the most.
Maybe it's not such a bad comparison after all.
