I think my prayers have been answered
That sounds great!

Mo,
Check out this link. Huge amount of tech info regarding ignition modules and advance curves

Bob

the pn#17316A1 sounds like a winner. Now does anybody know off hand if thats the "riser mount" type or is it on the dstributor?

Cal,

i did a search for you and this is the picture that is related to that part number. i found it at: http://www.lowerunits.com/precisionparts/263.html

Hey Mo-power did you not say you locked the dist on the dyno ??
don't you have blown 540's
why are you all for installing a module that will not have advance until 1750 ??
We've done not one but hundreds of blower motors with locked advance and it works like a dream ,it starts good idles great and gets great fuel milage ,I don't know why I care but its the cheapest way and best to go ,,why not try it ???Again I don't know why I'm concerned but let me know ,thx

Bobby,
I'm not blown , I suck ....Nah , wait a minute...that didn't come out right
I need a module that won't do any timing changes till over say 1400/1500 rpm because at my idle speed 800/900 rpm my current module already has some advance and when in gear it drops and looses that advance which lowers the idle even more
Now if I had the afore mentioned module I could go in and out of gear in the 800/900/1000 rpm range without the timing changing and exasperating the problem

Mark,
thanks, that looks like what I'm after

10-4 ,I follow what your up to I thought you were blown and not much static comp,and the lock down is great because it stops the hunting of the advance and other weird problems ,oh well just trying to save some bucks so we can get you 2 MSD's ,,I mean Crane boxes
