Holley Transition Circuit Tuning

[TT5.9mag]

Don't know how I missed this, but thank you. I appreciate it.

To your point about finding someone who really knows their **** - that's a challenge. A lot of folks seem to understand the basics of Holley tuning, but the more nuanced stuff like transfer slot restrictors, emulsion bleeds, etc., aren't as easily understood and are probably even harder for the few who do understand it to explain it to others over the web.

Thanks again!

Become one of those guys that knows their ****. You’re already on your way. Drill and tap the TSR and put a plug in it. See how the engine responds. Then put .100 hole there. See how the engine responds. Trial and error will help you understand way more than reading it online.

Thanks. I've been working on it as time allows. It's fun to tinker with. One thing I've found interesting is that my observations have differed from what I've read from a few folks. If nothing else, it shows me who knows what they're talking about and who doesn't. haha.

My comparison to tuning a carb is like building a house.

Idle is the foundation that everything else builds on. If the idle is fubar'd, there will be compromises in the subsequent circuits to cover any inefficiencies.

It's fun to tinker with the stuff and when they are right, it's really nice. Problem is there hasn't been a good factory holley profile across the range in 50 years.

You may be right but it doesn’t mean they’re wrong. Different carbs can act differently, aftermarket main bodies don’t do the same things holleys do for instance. Aftermarket metering blocks absolutely don’t act like holleys. So make sure when you find information you’re comparing apples to apples. If not use it as a guide and test it on your own carb.
