J Jensen: Without getting on a soapbox let me reiterate Brents comments. I am one of the few here who run a relatively highstrung 289 with 48 IDA Webers in a street environment. With Webers to get a 289 to RPM to 8000 let alone make power at that RPM the chokes will need to be about 44 to 45 mm. it will require 12-13: 1 Compression, the required cam will be unusable at anything below 3500 RPM with NO low end torque, at the very least at which point it relegates the car to a track only application unless you are running 4:56 gears at which point you are spinning about 4000 RPM at 60+ MPH . Requires aftermarket block, Expensive rods ($1300) Steel crank $1700, Heads with Shaft mounted rockers $4000, Webers $3500 and on and on. Huge Money. When done it will be a maintenance nightmare.

You may dream of an 8000 RPM SBF push rod engine, but unless you are ready to drop close to $20K + for a fully developed engine you will be well advised to rethink your project ore retitle it : Bench Racing 101.
