I recently completed a 250 install for my 66 Bronco. The 250 is from a 1970 Mustang all stock and the PO did or had a valve job done. It starts up and runs fine with the Carter carb. My friend did most of the work on the DSII from the pic and pull and the timing is set to stock as well as plug gap. I am using the module, plug wires and coil from the donor vehicle for DSII, they look ok but when cruising at any constant speed I get an occasional miss, very brief and one day during some extended wet weather had a noticable miss under hard acceleration so probably plug wires need replacing. Will check on a moonless night just to make sure. I am learning confirm everything I can.
So I want to replace the plugs and open the gap a bit and advance the timing a little.
Also want to modify the DSII for faster advance.
A friend has a Jacobs coil and some spiral core wires, Accel I think he said that he used for about a year before he put a v8 in his Bronco that I can get real cheap like $40.
Did some research of past forums and the Autolite ap46 and app46 and ngk 7510 seem well regarded and I beleive these are extended tip plugs. I had looked at some of those Bosch plugs with two electrodes because I considered indexing my plugs. Is indexing going to yield any appreciable difference with what I have?
Also does this seem like about the best ignition system I could have for the money. I plan to carry a spare DSII, coil and module with me for offroad emergencies so that pretty much excludes DUI and MSD ignition from a financial perspective.
Looking to get the most performance out of what I have until I can get another head and mill for 2100, 3 angle, port and polish etc.
Thanks for everyones help so far, this site is great for six cylinder junkies. Also the Falcon manual, I am constantly looking at that. I still just get polite blank stares from my friends when talking about modding Ford sixes.
I appreciate any and all input.
