What Carb Are You Using??

[Twoblackmarks...]

Mild Winter this year actually, until suddenly there was 1-2 months With Extreme snow every day.. But good now! Today you could burn Your tires and the marks would have sticked too the road, that`s when the weather is promising! The problem is I thought I had good time through the Winter getting my car ready, but suddenly summer is almost here! Yipes! (As usual..)

On the carb side, dyno tuning is good to find HP. But I think an Wideband O2 sensor is good to use to tune yourself, I think that can get you far, if not Perfect too, I have not used that myself, but I am gonna try to the summer. So maybe I regret writing this then! But I think an Innovate type logger is best, so you can drive and log how it Works and look over it afterwards and try changes, time consuming though. But fun to tune! And you can use it on more than one car, I Guess a weld in O2 bung is needed to get the best result though.

And the idle setup, if that is good adjusted it Cures most usual "driving" problems it seems, have a good working transition and such, especially on big cam engines, I Guess idle air bleeds is Nice to have then, so you maybe dont have to drill the throttle blades and such.

David Vizards Holley Carb book is Nice, (A New one) I like everything he Writes, since it is easily understanded, even though I often must read stuff many times over again to really understand it, it is written in normal Words and phrases for regular Joes to understand, even if it take a couple reads still to get it in my head... And even then I forget it after a couple days..

But I am in no way an expert on carbs or tuning if I seem to "be that" or make myself to be it, but while I am not on Warren Johnson Level, I am hopefully not totally clueless either

When I did my 3" mandrel exhaust I did put bungs in for 02 sensors. That's as far as I got on that. Cam is not that big and don't have idle issues. Have a part throttle stumble, just recently. Haven't touched it in years, may need a basic clean up, oh kit. We have 15% ethanol (or 10% can't remember) A person can learn something from every and anybody! I check out that book. Thanks
And I, LOVE MAKING BLACK MARKS TOO!!

What is this Carb you speak of?

[surewhynot]

I have had both a holley and a demon on my 327. the demon was a road demon in the 650 range cfm (purchased almost 10 years ago) holley is a 2 corner idle 650 DP 4150. The demon was pretty far off out of the box but when dialed ran pretty well, although it was always a bit rich, i have heard from several people demons are generally bigger than advertised. The holley has been more manageable in terms of getting the mixture right, and seems to run better to me, could just be mind games. If you want a holley go to ebay and find holley's store, that is where i got mine, than are deemed refurbs, but the holley tech i spoke to said that they are generally new carbs that someone bought ran and didnt know how to tune it right so they returned it as defective. Then holley goes through it (replaces parts as needed) then retunes it. My carb looked brand new when i got it. They normally have a good selection there too, mild to wild.
