Re: Replacing my carb, what will match? (dukvet76)
Get a second opinion on the carb replacement. If the carb has a good rebuild, you should be able to tune it with the help of Lars. Drop him a line with the info you list in your thread. I did and I am very pleased with the results. Lars has helped me to dial in my carb performance with the replacement of the main jets, primary metering rods and secondary metering rods (after he performed an excellent rebuild).
Unless you are generating 500hp, I'd say save your money and tune that q-jet. It's good for 795cfm! :seeya

Re: Replacing my carb, what will match? (dukvet76)
650dp gets my vote. dont really need a 750 for a 350 cu engine. Im usin a holley600 vac sec and its plenty enough for my setup. i jetted up one size in the primarys and 3 sizes in the secondaries as well as using the lightest sec spring for a sooner opening.
