you stated that Barry Grant inflated the CFM numbers. He did not. Actually Holley did, with their 950, that really flowed around 800-830.
so..why didn't that high end flow equipment you used at Holley, pick that up ?
If the Holley test equipment is so ultra-high end, how come they put .037" idle jet orifices in carburetors,
then you have to tell everyone here to change it to a .031" ?? that's 6 sizes off from the factory.
take a 400-428-455 stock Pontiac engine. bolt on a Holley 850 4781 DP carb brand new.
run it for 5 minutes. pull the plugs.
what do you see ?
black as coal tar.
how do your eyes and nose feel while the car idles in the garage ?
I've got 40 years of experience with these myself as well.
They run too rich. They always did. Let's be frank and honest about this.
