Holley Stealth Ram, Commander 950 EFI and Cam Swap Shopping List
Since I had a bent valvestem in the ‘68 Camaro and the head had to come off to be repaired, and I had three months before the next SCCA Solo II autocross event here in Honolulu, I decided to take the plunge into the Electronic Fuel Injection (EFI) realm that I had been planning for over a year. The first thing I did was make sure I had as many things ordered as I could think of that I knew I needed for the conversion to EFI. I had already ordered the Comp Cams Camshaft (PN 12-465-8), retro roller lifters (PN 853-16), pushrods (PN 7809-16), timing chain set (PN 3100), and the full roller rockers (PN 1416-16) discussed in an earlier blog, and they were all in my possession by now. Additionally, I had a Holley Stealth Ram intake, with fuel rails, injectors, a wiring harness, upper plenum, and with a BBK/Edelbrock 58mm throttle body that I had purchased used on eBay. I had to order the gaskets that mate the intake manifold with the upper plenum (Holley PN 108-119).
I had the GM small cap computer-controlled distributor with an MSD external coil (MSD Blaster GM coil PN 8226) and MSD Street Fire spark plug wires (MSD PN 5570). The MAP, IAT, and coolant temp sensors can be sourced from your local auto parts store since they are OEM for ’92 Camaro (and many other applications). I had already installed the Commander 950 along with the Bosch wide band oxygen sensor (Holley PN 534-197) and the Holley in dash Air/Fuel ratio meter (Holley PN 534-200). I had installed the wiring harness at that time and since the MAP sensor was a simple plug-in, that was installed as well by plugging it into the wiring harness and running a vacuum line off the carb to the sensor. It was not secured anywhere in the engine bay yet, just handing off wiring harness. For fuel plumbing, I had purchased a Walbro external in-line pump rated at 255 LPH (PN GSL-392), an OEM-style fuel filter (PN GF481), five feet of 3/8” rubber hose for fuel injection (rated SAE J30), and two five foot long 3/8” steel brake lines, pre-flared with tube nuts on them already.
