You know this is why I still have a stash of thremoquads...lots of people hate them but if you know what your doing its an 800/850 cfm carb that will work on a 318 to a 350 Chevy to a big block mopar... And has come in 1000cfm rating for rare racing versions nothing is like the sound of a thremoquad built right at wide open throttle!... Some one needs to make a modern version....and I don't mean the demon version currently being made.
Thermoquad is CDa great carb as long as the phenolic body doesn’t get a hole in it. Lol. M air door carburetors are a great solution to the carburetor sizing issue. Thermal, quad, Quadra jet,and AVS really were all great bulletproof units.
Nice!! Great topic!!! I used to run an Autolite 2100 on the Dodge big block I had. "The Thermoquad was junk." I like the 2100 because it is simple and worked well. I switched up to a Quadrajet for the only figure 8 race I ran that engine in and was able to get enough rpms to bend the pushrods in #3 cyl. My thought is if you are not making vacuum at redline you don't need more carburetor. Assuming the carb (and engine) is tuned correctly. But speaking for the street less is usually more. RAWK!!!
Happy Tuesday Mike. Great topic. I for one have always been one for smaller carbs. Mainly street engines and or street drag combo's. I have dialed in factory carbs and done tricks to them, that made the carbs work for the application just fine. Also working on engines in racing where only two barrel carbs are allowed and seeing the horsepower that can be made out of 350 to 360 engines with a 2 barrel carb is impressive. In the old days we used 650cfm on small blocks and 750 to 850 on big blocks. Made big horsepower small blocks with 750 carbs. Also, in the old day drag racing guys ran 750's because the tune was not effected by barometric pressure when running a circuit and or divisional races. When racing at different altitudes. I liked the old days when things were practical and more a common sense approach. A small carb will never hurt you as much as to big of a carb will. Dependability, drivability and efficiency are good thinking for your street driven vehicles. The Basics will never fail you. Just my opinion. Have a great day. Take care, Ed.
I never saw the first video, and don't know this formula you are speaking about. I do know that my 83 Nissan Sentra hatchback had a bad carb and they couldn't find a replacement anywhere so the mechanic put a Weber on it, and blocked off all the vacuum hoses that the original carb had running to it. My car ran better than it ever had in the entire time I owned it, and got better gas mileage as well. It probably wouldn't pass the emission standards in some states anymore, but it was fine for where I live. Best decision I ever made was telling him, "You want to put a Weber on it? Yeah, go for it!" Stay hydrated, safe, and healthy! 🤟RAWK!
I had a 92 Ranger 302 with a 600cfm holley and an e303 cam, dynoed at a hair over 300hp and 320tq. It had a c4 with ~2800rpm stall, 3.73 rear axle, and ran out of gear at 113mph. It was a fun daily driver and plenty quick. Ran 3000-6000rpm frequently. I also had a 79 F350 4x4 with a 429 that ran a 600cfm holley. Unknown "rv" cam, and a c6 trans with a basically stock converter. 325hp and 480lbft torque. It ran well and was also a daily driver, but never saw over 4400rpm. Probably the same list number from holley, worked well in two very different applications when tuned right. Now I'm getting ready to dive in the deep end with the Mustang: 460 with dual 600cfm vac secondaries on a blue thunder "high rise" intake. It sounds like I have a thing for 600s, but I have had others, I swear 😅
0-1850 Holley 600 cfm most likely. They sold 1 million of them. I probably have another six or eight of them kicking around. The other one that was really popular was the 0-3310 750 CFM. Thanks for watching squirrel
It's not an exact science but you can get it close and experiment with sizes. Playing with different sized carbs is fun if you can get a few good used ones.
Kool!!

Another awesome video
Thanks again!
Yep I can hear them now! Duck in coming...building a bunker as we speak-type LMFAO!!!! they're throwing motors LOL RAWK!
As long as you’re throwing big blocks, I’m OK😂
