I think I need help 🤪
The one in the middle, black anodizing. 650 cfm, air velocity is faster vs 750, that‘s why it behaves better in this heat. But it also won’t flow as much at 6000+ rpm. Big carburetors on little motors, there’s always trade-offs and compromises.Which one did you say tolerates the heat better?
I had the opportunity to buy a ‘68 427 car in my early-20s. I couldn’t scrape up enough $ in time and missed out. Fast forward a few decades… I can now say it’s probably for the best because I’d have wrapped that thing around a tree.
Thank you 😎P
Personally I fail to see the logic of asking for or thinking you need help . Looks like your doing a fine job by yourself getting them carbs .
And some nice ones they are too unless I miss my guess.
Yeah, gotta have timing & PCV all squared away. Ignition all has to be 100%, no vacuum leaks, fresh gasoline, stable fuel pressure. Without all of that, carb tuning is just chasing one‘s tail.Looks like nice work! I finally did some screwing around on my Holley. Starts a lot better, stumble mostly gone. Only 10" of vacuum though. But at least it's steady.
Next step is I think I need to retime it. Part of my problem was I had the advance hooked to manifold vacuum. Seems to like the timed port better. I also adjusted the squirter cam position.
Only issue now is I borrowed my timing light to my neighbor to use on his boat. He then sold the boat. And forgot my timing light in the hull!
You‘ve built a nice piece, lots of good parts 👍View attachment 855261 '66 289 .030 over, balance and blueprinted, factory cast iron heads (ported/smoothed I'm told) 10:1 Probe flat tops, Comp Cams high energy FS 268H-10, pertronix III ignition and flamethrower coil, factory dizzy, motorcraft plugs, Holley 4776-7, 1" open spacer, edelbrock performer dual plane, long tube headers, billet flywheel, centerforce clutch, 3spd that someday will be removed for a T10.

Had the pan off a number of years back, think it's still 289 stuff.
