Hogging out a 700 cfm TBI for more flow, adding 1.6 rockers to open the intakes even wider, on a performance camshaft, seems counter productive when looking for mileage.
Thats why I was asking. A factory GM TBI for the 5.7L flows around 450 cfm. You can buy a a OEM TBI but with the throttle bores bored to 2" and with the throttle shaft, and the throttle body iteslf cleaned up from casting flash. I did not know if it wsa worth it or not? As far as the rockers go, it was also just a thought. I figured that part would probably have to stay 1.5, but thought I would throw it out there.
