I was considering using a distributorless ignition system on a 455. Does anyone know if it is alright to run without the distributor? Will this do anything with the cam? ________ Cancer - breast forums
well you would still have the same load as you would with or without as you would need a dummy set-up to run the oil pump. Don't know if anyone makes such a thing for a Buick if guys just stick an old points unit in the hole? Ken
A crank trigger setup would be more accurate than a distributor as there is no timing variance due to slack in the timing chain. You'll be able to reference true crank position rather than having the timing move a couple degrees from the slack in the chain. On the Buick 231 turbo cars, the cam position sensor is installed where a distributor would be on an NA 231. You may be able to modify a GN/Turbo T cam sensor to work, even if it's only for an oil pump drive. GM 2.8/3.1/3.4 engines still use a dummy plug to drive the oil pump since they haven't changed the basic design from when that block was originally used with a carburetor/distributor.
I'll need a 36 -1 tooth wheel and sensor on the crank for the Ford EDIS system. Not sure yet how it will be mounted, but I'm sure it will need some custom bracketing. I don't like the idea of a cam mounted sensor for all the reasons you described. That, and it would have to be a 72-2 tooth wheel, since it's turning at 1/2 crank speed- could be a little too big. ________ DolceSecretary
