Fine if it's tuned well and better with a manual transmission than automatic.
Yeah, I never figured it would amount to much more than just helping me prevent against vapor lock. =P

The other that interested me is the Street Demon, which is based heavily on the Edelbrock design. I talked my brother into trying one on his 351w and he loves it. Unfortunately, the smallest they make is a 625cfm and I didn't feel like going with a big carb again.

It was actually the first time I took it out since I had it adjusted.
Yeah, I had a secondary metering block on my 465 and liked it. Interestingly, the QF carb has jets in the metering plate, so even though it doesn't have the whole block, you can still adjust it. I wonder what difference it makes going with one over the other.

That does look great. I remember reading you got one and it sounds like that's really working well.

Their nomenclature simply says it's a protective coating and "good looks" . Blocks oil, grease, fuel, grime, etc. and acts as a mild heat barrier. 6% isn't a very big claim, so I imagine there's some validity to it. Dunno. If it helps, it helps. Also, I agree, looks pretty good.

I always thought a black paint/coating would absorb more heat. I was always told dark colors absorb heat and light colors reflect more heat. Whether it does or doesn't block heat, the black does look good! I'm going to paint my Autolite 2100's black. If I can find a paint that won't be effected by the gas & heat.



Now that you've tried most of the 4V carbs. When are you going to start trying some multi-carb set ups???

I believe that is only the case when it comes to heat sources from light (such as the sun) since light colors reflect light away, whereas dark colors do not. When it's under the hood, it's irrelevant.

Lol, I think that'd be really really fun to try. But if I ever went with something else, I think my next foray would be fuel injection with a MegaSquirt controller.

I think we need to add one bit of info that AbandonedBronco omitted: He was dealing with a used carb, and any used carb might have orifices enlarged (drilled), or any number of non original mods that are not known but to a carb guru.

I have a new 1848 and love it, with zero problems, and run 57 primary jets with 67 secondary ones, and my engine loves it. I wanted to pass that along to all those who might read this thread and get the wrong idea about an 1848.

Oh absolutely. I tried to reiterate that earlier. I think the carb is fantastic and a near perfect fit for the engine. I loved mine. I just started having some problems specific to my particular carb and didn't feel like dealing with them, so used it as a good excuse to get the one I wanted. A Holley 465 should'a, would'a, could'a come stock on the 300.
