Carb size ?
A max size carb per rules for each motor combo. I know we no longer need carb numbers to be correct per engine. Any rule on how small a Qjet you can have? Asking to try a small cfm if legal.

Re: Carb size ?
Carbs still need to be the original Specs/Dimensions including boosters/Throttle blades. have
I prefer the Edelbrock Replacement Q Jets. I have several in great shape and even NOS.! I believe a 750 must replace a 750 and 800 replace a 800. You can easily look down the throat to see the difference. Believe it or not = I used to race a National Recording Holding 86 Ram 100 with a Q jet.

Re: Carb size ?
Yeah, I wish that this were true John but look at all of the replacement Holleys that have "down-leg" boosters. The only thing that matters anymore is throttle bore and venturi size.

Re: Carb size ?
Not since they let the Edelbrock Q-Jets in.

Fortunately I have almost 200 Thermoquads on the shelf. Plus 25 Q Jets. When my son Jon was about 5 = I gave him a big high sided garden wagon and a Wallet full of $5.00 Bills when we went to the Pomona Swap meet every month. Then he would spend the weekmend trying to buy every Thermoquad he found for $5.00. A few of the Mopar racers on this site still remember seeing him every month and selling him a few. He is pretty familiar with them by now 25 years later.

Just a bit of advice, don't listen to what some "previously employed by NHRA" people might have told you.
