Why yes. I believe you covered that in about every perceivable way. Nice work! :D

Do you have a TQ to put that gasket against? I wonder if the throttle bores stretch to the outer limits of the spread bore gasket. Maybe try and line a square bore gasket up to the bottom of the TQ and see how much of the gasket you would need to trim up to just uncover the throttle bores. Then...

Same as if it were on the factory CI manifold or another spread bore manifold. The notches and troughs between the port and the throttle bores allow for vacuum to pass from a sideways perspective. On an open spacer or open manifold, the ports are just exposed from the bottom instead.

Well.....the Holley/Demon Street Demon looks like a TQ and bolts onto a square bore intake. If I were to ever stray from my Holley, this would probably be the first carb I would try.

Should be fine. Seen quite a few dudes use them on early motors.

I did not check the A/F, nor did I change the jets, but interestingly enough, when I decided to pull the 650DP and give it a rebuild, I tossed on a new-ish 600 Eddy temporarily and the same thing happened. Just felt like the motor forgot how to motor. I had never been more excited when I got the...

On the stock 22" 3 row radiators for the 70-72 340 Dusters, what size were the core tubes? My 71 came with a 4 row when I bought it, but has always has trouble keeping it's cool. Ive flushed the thing, boiled it, etc, but it always runs on the hot side in warm weather. Out of clear random, I...

I had made the decision to swap the smaller carb after reading a few carb comparison articles. On a small Chevy, there was a comparo done between a slew of Holleys from 390 up to 950, all mechanical secondaries. The difference in peak and average power from the 650 to 750 was so slight, probably...

I have a build that is fairly similar to yours. Being a 360, it does have the bigger stroke, but it's about 10:1CR, Lunati Voodoo 268/276* .494/.513", Mild ported J heads 2.02/1.60 valves, stock iron exhaust. Originally had the Performer and a 750 DP on top. Then, I swapped to an RPM (non air...

I had a 750 when they first came out. I kept having weird stumble problems no matter what I did. After a while, I talked to their CS rep whom asked me to send it back to them. They sent me a new one and it was one of the most responsive carbs I have ever used. Apparently, some of the very first...

I use the Summit Orange "resto" wires with the 135* ends. Seems to work quite well, and keeps the boots away from the manifolds. I think Packard makes them.

My Duster also has the Espo +1 springs. These have been on for a few years, so they should be completely settled. Just pay NO attention to the rusty quarter panel. Ill get to that soon. lol

I have seen these fans make holes in hoods, even with shrouds.

I would leave the front as is. The rears will settle after some poundage and probably sit about an inch lower when settled. My Duster went through the same resting process with the same ESPO springs.

Some of you guys might want to check your valve lash or preload. I have an older mechanical rocker arm set up with the iron arms and adjustment screws in my 360. My engine would always get a bit hot, so after going through a few things I decided to check the preload for ***** n giggles. I dont...
