Uh, if you don't believe me call the folks that built your converter, or check out a web site. You want 1/8" to 3/16" clearance from the flexplate to the converter pads before bolting it up. If you have too little clearance (less than 1/8") it will trash you pump, too much (over 3/16", thats less than 1/4" for those keeping score at home
) and the converter may not drive the pump properly, and also ruin your trans.
Regardless of the washers you use or don't, shoot for 1/8" to 3/16" total gap before sliding the converter back and bolting it up. You also don't want to shim the converter out of the crank pilot, so if you need to come out too much there is an issue.
Yours is perfectly normal, I would definitely put thin washers in between to get the maximum 3/16" though.
Here, I found a install instruction sheet on Coan's website Coan install PDF
, but if you look at any converter mfg's site 1/8" to 3/16" is the constant you will find.
Guys that say always pull it out to the flexplate have just been lucky, you don't want it jammed up into the pump with no clearance but just as dangerous to your slushbox is too much....
