Would like to attempt this project this summer. This is some of the information I have gathered. Much of this information has been collected at "High Tech for Old Iron" on the V8 board. Anybody in for filling in the gaps to make this project easier for DIYers. There is a lot of great information at http://www.megamanual.com/v22manual/minj.htm#fb Kits by vendors: Mass-Flo EFI, Inc West Brookfield, MA Tel: 508-867-6733 / http://www.mass-floefi.com/mass-flo.html Rance Fuel Injection Service Genesee, PA Tel: 814-228-3800 / http://www.rancefi.com/ (thanks Stg1Regal) TA Performance Phoenix, AZ Tel: 480-922-6807 / http://www.taperformance.com/ Necessary components to consider: Intake: Single plane intake preferred SPX intake from TA performance has port injection fuel injector bungs already in place Folks that can modify intakes: (standard intake to port fuel injection conversion, weld in bungs plus drill for injectors, fabricate the fuel rails, weld on the fuel rail brackets and machine work associated) Young's Performance Decatur, AL - TEL: 256-351-9949 / http://www.youngsperformance.com/ $375 in 2003 dollars. According to Kerry, you supply the SPX manifold and fuel injectors used for setting the rail height. Force Fuel Injection Miami, FL - TEL: 305-235-6160 / http://force-efi.com/ Wilson Manifolds INC.

Lauderdale, FL - TEL: 954-771-6216 / http://www.wilsonmanifolds.com/ will take your intake and convert for $650 XSPerformance (Michael Tweedy - XSPerformance@iwon.com) - Covington, Ga - http://xsperformance.net/ Fuel bungs to weld into intake manifold: HRpartsNstuff - Atwater,OH - Phone: (330) 947-2433 - http://www.hrpartsandstuff.com/products/bungs/bungchoice.htm Information on injector bungs for port injectors by checking out http://www.sdsefi.com for injector/manifold installation information, along with lots of other great information. The bungs are 0.530"-0.535" inside diameter [about 17/32" or 13.5 mm]. The fuel supply lines for the top of the injectors are the same size. MSD and others have an Epoxy-In Pocket fuel injector bung as PN 2120 (set of 8). Holley also offers them as PN 534-83 for a four pack (~$50), 534-84 for a pack of six (~$72), or 534-85 for a pack of eight (~$94). Fuel Rails These serve two functions: they supply fuel to a multiple number of injectors, and they physically secure and locate the tops of the injectors. Many place supply blank aluminum fuel rail extrusions in whatever length you need. One example is Ross Machine (http://www.rossmachineracing.com/products.html). They have two styles of fuel rail extrusion. They can also create custom fuel rails for you, with the injector holes placed to suit you. The aluminum extrusion comes in two sizes: * Dash 10 (.800" Bore) - $10/foot, and * Dash 6 (.500" Bore) - $12/foot. Throttle Body: EFI Spyder "Power Elbow" Coast High Performance (CHP) - Torrance CA - Phone: 310-784-1010 / www.coasthigh.com for right at $140 (polished extra) It will accept any size throttle body up to 90mm with no modification.

The fuel pump opening on the Turbo Regal tank is about 3", vs. 2-1/2" on the 70 thru 72 Skylark tanks. The Turbo Regal style pump (HP Walbro replacement) can fit through the stock GS tank's smaller flange, if you trust the fuel hose to hold the pump in place. Use a new 3/8 line and use the 5/16 for the return. The pump works all the way till the gauge gets to "E" just like with the stock arrangement. Cut the sending unit's pickup tube off so that the inlet of the pump's filter sock will sit about where the pickup tube terminates. Put a bulge in the tube using a flare tool to help keep the hose on with double stainless steel hose clams. Drill out the 1/4 return line in the sending unit and replace it with a 3/8 tube soldered in. Take the 3/8 inch tube to near the bottom of the tank and use plastic straps to strap the pump to the return line as well. Use the bulkhead electrical connector from the sender from a tbi equipped car and retrofit it to the Skylark tank fuel level sending unit to supply power to the fuel pump. Fuel Lines 3/8 inch fuel line from tank to fuel rail 3/8 return line back to tank Need to collect data on sizes and lengths plus fittings for flexible and steel tubing to assemble the system.

It looks like you have spent a lot of time doing the research. Have you figured out yet what the final price of an EFI system for the BBB engine is going to cost? I appreciate the list, as it had a couple of sources I didn't know about. Later, Randy
