A 750 vacuum secondary is not to big for the street. most of the time it will be on 2bbls and be pretty snappy. it needs more air flow, heads are where to start. stock valves don't flow for crap. good valves and good valve job, some minor bolw work will make a Huge difference.

It'll work if you know how to set it up right but would there really be much noticeable power gain over a 650 on a mild engine like that? And how much flow gain just from 1.88 to 2.02 intakes if they both have good seat and bowl work? Just curious as you're obviously a highly experienced pro at this i love reading about your builds.
