Whoa!! Hold up on that Q-jet copy! There are not that wonderful. I have worked with many. This is my second attempt at a reply,,server keeps dropping me, hope this makes it through!! Stick with an OEM type Rochester or Carter built Q-jet. I build about 60-70 a year, from daily hot-rods to all out racing carburetors. If matching carb# is not a factor, I prefer to use the pre-ECM carbs with the adjustable metering rods and elec. choke. These can work fantastic with non-stock intakes and other parts. Not to mention, easy to tune and buy performance up-grade perts for,(not that much is needed). These are available to two sizes/configs. Both are suitable for mild to wild apps. with A/T or M/T usage. Feel free to E-mail ma at: speedy_87ss@yahoo.com I am new to the site here and hope to help where I can! Take care,,Jeff (speedy)
