New EFI Intake Manifold

Any updates

Not much progress really to talk about. The engine that will be used for dyno testing the new intake has been back and forth to the machine shop several times for various reasons. I am also waiting for an oil pump mid-plate.

On top of my RPM AirGap I have a custom 1/2" blended open spacer, a Wilson 1" tapered open-plenum spacer, a Pro-Systems 950HP carburetor and a 14" x 4" filter with a circle-track drop-base air cleaner (profiled to improve airflow) and just fits within a slightly raised but otherwise stock cowl-induction hood. Intake has some plenum work and runner/port exit blending to Indy SR heads, 250@0.050" solid roller cam, 1 7/8" headers, dual 3" full exhaust, T56 transmission.   

Cruises in overdrive just fine at 1800 rpm and has lots of low-to-mid-range torque. Combo wants more intake, but used the AirGap since I already had it. The new intake Edelbrock is developing sounds like it would get the most out of the rest of the combo, so waiting instead of trying a Torker.

Thanks,RD

Not much to report, but the test engine block is finally back from the machine shop. Rotating assembly may be back by the end of the week.

The block looks good!
