Re: Might this be a good intake for 4150-to-4500 conversion?

...Always been a 4150 guy, but wondering what something like a 1050 Dominator on a decent intake might do for it.... - Brad A 1,000 + CFM 4150 would be a bolt on for your and many other manifolds; just saying... My biggest 4150 is a 1.58" v annular that wet-flowed about 950 CFM at AED. It may be al...

Might this be a good intake for 4150-to-4500 conversion?

Just another one of those lightbulbs that flip "on" in my head... If I get serious about trying a 4500-type carb vs my current 4150 options, would the Trick Flow 4150 intake that I have now be a good candidate for doing to the plenum & mounting pad conversion to turn it into a 4500 flange? I actuall...

Re: Small block Mopar fan's new toys!

The set I'd seen a couple years ago surprised me in how low the short turn was. Edelbrock went to all the effort to design a new raised-port head, but IMO handicapped its potential because of that one thing. Can you post pics showing the SSR, to show if my memory is correct?

Re: Why does a tighter lsa need more compression?

Sorry, I'm a Joe Amateur here. But, if you're saying cranking pressure doesn't mean sh!t, you must not have dealt with -- or have forgotten about -- pump-gas builds of "old school" no-quench, iron-head, big-block street/strip engines. As long as my own cranking pressure measurements were taken the s...

Re: Does fuel movement in bowls during acceleration impact AFR?

Even if the jets remain covered and regardless of what is happening with the float and needle and seats, wouldn’t the relative increase in fuel level at the front metering block and the decrease in the fuel level at the rear metering block directly affect the emulsion circuit. As well as provide a ...

Re: Does fuel movement in bowls during acceleration impact AFR?

Simply plot in- line G forces against lambda values. The a/f shift due to G forces may be obscured by variations (jitter) in Lambda readings. And I thought it was a pretty obscure question, only to have found this thread from years ago: https://www.speed-talk.com/forum/viewtopic.php?t=26474 I must ...

Holley and Moroso make jet extensions to help with secondary fuel starvation under hard acceleration.
That's what my qualifier "... assuming that the jets remain immersed in fuel" was intended to cover.

Does fuel movement in bowls during acceleration impact AFR?

When a carb is installed in the traditional primaries forward / secondaries rearward configuration: a) Does fuel being pushed away from the secondary metering block during acceleration affect the AFR, assuming that the jets remain immersed in fuel? b) And, conversely, does fuel being pushed toward t...

Re: Any experience w/ Braswell 14"-15" tapered air cleaner?

Braswell says their tapered filter is 14.25 to 15.25. The Allstar base looks similar, but I can't tell if it pulls back from the filter base like the Braswell, or is more vertical / more restrictive, especially without having the benefit of the tapered filter element. I've looked at the reproduction...
