the best carbs are 660 center squirters all others feed most of the accelerator shot down 2 cylinders and starve the other 2 hence the bogging problems inherent with these setups the 660s sqirt a 4way shot down the center of the carb and tend to charge the cylinders evenly. They cost a mint now ebat runs 500-600 apair used i dont think holley makes them anymore. They were designed for dual 4 applications. usually only double pumpers are mounted sideways since they dont fit ny other way vac sec carbs are usually mounted inline.
