For those of you who read my introductory post about being the new owner of chassis 3820, you’ll know that I’m in the process of pulling the non-running EFI system that was on the car when I bought it in order to go back to a carburetor.
After spending the better part of last weekend pulling about 75% of it off, I have some questions regarding replacement parts and what I might be able to retain from the EFI system.
I’ve spoken to Larry at Pantera Parts Connection in Carson City (real helpful guy) and he suggested going with a Duraspark ignition. I’m somewhat familiar with these from my many years in the first generation Bronco hobby, but the Broncos I’ve owned over the years have all been too early to actually have a Duraspark setup from the factory.
So, questions about the Duraspark setup:
Is that what would be recommended by the members here on the board?
Is there a noticeable difference or reason to choose between Duraspark I and II?
I still have the TFI distributor and coil from the EFI setup installed. From my research, it appears that I cannot use the TFI distributor with the Duraspark ignition, but I can use the TFI coil. If both of these are correct, is there a particular distributor the board recommends? Is there any reason to not use the TFI coil? If for some reason it’s suggested that I don’t use it, is there a particular coil the board recommends?
Since the high pressure EFI fuel pump has now been removed and the stock mechanical pump was been removed when the EFI was installed, I’ll need to find a decent high quality mechanical pump. I see the Carter M6882 has been mentioned a few times. Carter is a widely used brand in the Early Bronco hobby. Is that the recommended pump for the Pantera, or is there a better one?
Larry in our conversation recommended a Quick Fuel carb that he stocks. Anyone here running one? Anyone have an opinion about this as a choice? Any other suggestions?
I realize a lot of the input on parts has to do with the engine in the car. Looking through the receipts and engine info that came with the car, I believe the engine has a Ford Motorsports M-6250-A342 camshaft and has a compression ratio of 10.54:1.
I’ve included dyno test results below. If this info influences any of the recommendation on parts, please take it into consideration.
