| Post subject: | HEI Location UPDATE!! |
Ok I finally got my HEI hook up. I used a module I picked up from the salvage yard. I mounted it to a heat sink that I had laying around from a computer processor. It ran ok for 24 hrs with the lean burn distributor. Then we installed the electronic distributor the following day. I drove it home, went out later and it wouldn't start. After some trouble shooting we determined the module had gone bad. So the next day I went and had the module tested, it tested fine, so I replaced the stock coil with the blaster 2 coil, still would not start. So it was time to buy a module. Had the module test at a different auto parts store and it tested good again, but they said it heat up pretty fast. I said i'm replacing it anyway. If you've read this entire thread you know i wanted to mount this in the original location of the Lean Burn computer. Well I disassemble the computer and found that after pulling the electronics out of the housing I was left with an 8 3/4 inch X 4 inch area for a heat sink. So i picked up a piece of 1/4 in aluminium plate to fit in the housing, shouldn't have any heatsink issues. Some would say that I went thru allot of trouble to mount this module. But the housing is designed with 2 openings one where air is drawn in by the other opening that is connected by a hose to the breather intake hose, there by drawing cooler air across the entire inside of the housing. I have been driving it like this since Saturday and have not had any issues so far. UPDATE: I checked my milage on the first full tank of gas since the conversion and with vacuum advance my mileage has gone from 14.8 to 17.8 or 27% increase, I guess I didn't have any vacuum advance with the computer on there. I am presently running a #59 jet in the 1920 carb and its still rich, so #56's are on the way. Also does anyone have a photo of the metering block for the 1920 that show's the correct location of where all the check balls should be? When my friend rebuilt the carb he said there was one loose check ball in there and I don't think there should be. Any help would be greatly appreciated. I would like to say thanks again to everyone for help with this conversion and all responses to this post. If anything changes I will let you all know. Thanks again everyone Dave |
