Converted this engine from SEFI 5 years or better ago no changes but the induction. only issue was the foam floats went bad and installed brass ones 3 years ago no issues since. Winter only adjust the idle feed screws about a quarter turn. I drive it any nice day and take 1000 mile or better trips often as well as around town. gets 24 mpg

The injected version only got about 20 mpg after months of data logging and tuning didnt preform as the carbs

Now my truck a 86 dually with a 460 built for towing would get around 14 mpg until the inner pivots of the twin I beams screwed up the alignment. have thought about CFI on it from time to time
