Not trying to take a dig at you Mark about the lack of data on the carb swap. Sure, I can imagine swapping a newer carb and seeing gains right out of the box.

I figured it may have been an apples to oranges scenario, but I think we all were interested to hear some of the mods done to the 3 Barrel by you or others. I've done a similar metering plate to block update on my dual quad setup on my 65. Certainly helpful on tuning.

Yes some people find it easier to go faster with modern carbs, and it probably is. There is always an element of satisfaction when any of us can make this old technology run the number, don't you think?

I originally took your post as a request for a discussion on how to make the carb perform better. I'm not claiming to have all of the answers, but not posting specific the baseline configuration is a challenge. I realize it is not a thread requesting specific advise on how to tune your 3 barrel on your car either but I would love to continue the thread. At the very least I'll probably learn a few things specific to these carbs.

I'm also not trying to pick apart your statement, but fast and faster are both relative. I suspect the 3 barrel can be tuned for WOT drag passes just fine. The modern 850 you have will do this well too, plus have the benefit of improved drivability and throttle transitions.

How fast did your car go in the past? What ET do you expect it to make with an perfect carb config?

I've got a few of the mechanical secondary conversion kits, but I want to try my hand at tuning the 950 before I install one of those.

I agree plug readings can be a useful tuing tool, but if you've ever tuned a cab with adjustable air bleeds or emulsion tubes, there are circuits which contribute to acceleration which are hard to read by the plugs.

I'm not trying to talk down to you man, so if any of these statments makes you feel a little punchy I'm putting it out for the benefit of others reading the thread who may not have your experience. Are you and I okay?
