Q jet question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 350 sbc with a TH350 and 308 gears in the diff. The engine is stock 1978 that has been refeshed. I am running a rebuilt Q-jet and it use gas like it was still $0.30 a gallon! Truck idles smooth and pulls a steady 21 inches of vaccum. Under acceleration(not wot) it seems like it is triing to hard and not going any where quickly. Timing is set right and no pinging. Am I missing some thing with the carb?

Thanks
Bruce
