thought he wanted to go fast...... with the right curve and appropriate carb that teen will wake up if it has a true 9.5 : 1 ...... the 750 vac secondaries are junk unless you add a secondary metering block, quick change diaphragm and to get the transition and cruise mixtures right is a nightmare ..... better off calling Patrick at Prosystems and getting a 700 annular carb ..... put one on a 360 edelbrock headed with a baby comp cams street roller and airgap and went 465 ft/lbs and 477 horse at 6400 the 750 r3110 was a turd as well on this engine ..... if your going to build a big inch small block or even a stout 360 dig deep and save your coin and plan ..... it's not as ezy as picking parts of a shelf and banging them together ..... in saying that definitely get your dizzy curved try your 750 , then if you can get your hands on a 570 vac secondaries or a 600 or 650 pumper try that in for size I will bet my first child that it will blow your mind compared to where you are now or even where a bunch of coin and all the time in the work will get you with that 750 they are JUNKKKKKKKKKK
