You need to get a Edelbrock Qjet calibration kit #1992

Jet as follows #75 primary jet .048 primary metering rod
use the yellow power piston spring under the primary power piston.
Install the big .049" hi flow needle and seat from the kit.
Your fuel pump must be capable of feeding the carb and keeping the fuel bowl full at WOT high rpm.

secondary metering. Start pig rich "CC" secondary rod and "B" hanger from the kit.
Install the hi perf accelerator pump .

recurve the distributor for 24deg at idle and 28 to 32 deg max timing.
(shorten the advance curve) vacuum advacne should be limited to about 10deg and be connected to the manifold below the blower.

A good super charger cam for the 144 is the Crane #113801 HMV278-2
Another good one is Crane #113821 H-288-2

You want a 2.08 to 2.38:1 pulley drive ratio.
I recomend a water injection system for high boost.

use cooler than stock heat range spark plugs with a non projected tip and .035" gap.
