More SBC stuff to sell as I'm going LS2.
This is the intake I was running on my Procharged SBC (~725 hp). It was built by Scott at SD Concept Engineering (http://www.sd-concepts.com/pages/cfHome.cfm) in Rhode Island about 5 years ago.
The lower half of the intake is a Holley Stealthram that is gasket matched to a Fel Pro #1205 intake and the runners were extrude honed WAY out from stock.
The upper half is a sheetmetal plenum with internal extended bellmouth runners. The side exposed to the valley is shielded and there is a PCV grommet provision in the intake under the plenum. The plenum also has a port on the bottom for the IAT sensor. His shop logo and nameplate could easily be cut off from the front and the welds ground down. I never got around to doing that.
Scott said he benched it at 305 cfm per port flow capacity where a stock Stealthram maxes out about 260 cfm per port. The extended runners inside the plenum help build more low end torque and cylinder pressure.
I made the thin carbon fiber top cover for the plenum; it can be removed to expose the nice bare aluminum actual plenum cover underneath. The lid is held down with stainless button heads and belleville spring washers.
The throttle body is a BBK 75mm ball bearing piece and hanging off the bottom is a Kinsler remote IAC housing with a 4-pin (square connector) GM IAC motor.
The fuel pressure regulator is from SX, the rails and fittings are set up for -8 feed and -6 return.
This intake has excellent cylinder to cylinder airflow distribution and under load has awesome throttle response. It will accept both standard length Delphi-style injectors or the slightly shorter Siemens Deka injectors.
I'm located near Sacramento, CA. I have extra plenum lid and plenum to lower gaskets that I cut on a CNC knife cutter that I will include.
Asking $1000 shipped.
