For the 455 sequential fuel injection project was originally going to file down 7 of the 8 tips on a standard GM HEI Variable Reluctor pickup, to provide one signal per distributor shaft revolution, instead of 8. After dismantling a HIG distributor, I see it has 8 tips on the reluctor trigger wheel and and 8 tips on the sensor as well. Am now thinking if the thing would put out enough voltage for the module to sense the pulse with 7 on each side filed off. Therefore was wondering if using an optical type sensor would be a better solution. Filling in 7 of the 8 windows in the shutter wheel, should get me the desired one signal per distributor turn or one signal per two crankshaft turns. This is of course is the reference signal for the computer in conjunction with the crankshaft sensor providing the timing. Installation instructions Any ideas, or experiences?
Thanks that would work out great if I did not need a distributor. I'm going to run a distributor in the 455, and not separate coils for pairs of cylinders
Loyd....Here's what I'm using with my XFI. Give this one a look-see, it's part# 77441 Dual-Sync, HEI/Male Post Style, Small Cap, Buick V8, 400/430/455 distributor. :TU: http://store.summitracing.com/partdetail.asp?autofilter=1&part=ACC-77441&N=700+115&autoview=sku Hope this helps...
I am looking at that one as well, using Kerry's old FAST classic ecu. I found an article for converting the referenced Accel distributor's signal to be compatible with the FAST classic. Sure alot easier (and cheaper) than trying to convert a crank-trigger to fit a Buick when you have all the other belt-driven accessories to consider.
