LONG: Faster revs, not more revs...

[beingblueeyes]

ITB= individual throttle body's (one per cylinder) here's a link to a Toyota v8 with itbs, notice the fast revs and throttle response

the 60% under drive would be useless because of both reasons, at a idle of 700 rpm your alt and water pump would be spinning 280 rpm and at highway speed (2000 rpm) every thing would be spinning at 800 rpm

i understand what youre wanting and trying to accomplish, i wont go in to detail but i will say as long as the valvetrain is as light as possible you would beable to spin the rpms up, i myself is building a 410 with a lunati pro series crank and rods and the lightess pistons found, with this in mind the topend has to match, light weight everything valves, rockers, springs, locks ( everything )


bottom line, its not cheap when you start hitting 8k rpms or above
