Default PTC 4l80 converter install question w/ Reactor flexplate

Ok I know this topic has been beaten to death, however I'm using a CDS/Reactor aluminum flex plate which is thicker than the stock flex plate so its throwing me off a little..

set up is a 4l80 transmission, PTC converter, Reactor flexplate..

here's what I'm looking at, this is route #1




I measured from bellhousing to converter pads at 1'' exactly using a 1/8'' ARP washer between flexplate and converter...




or... route #2

I can put this 3/16'' ARP washer in which should give me a bellhousing to converter pad depth of 1 & 1/16''

and a gap of 3/16'' between converter and flexplate which is about the max recommended gap... but it will give me better converter engagement into the transmission (1 1/16'' vs 1'')



any opinions on this?

isn't pump engagement more important than the converter flexplate gap, and since I have a thicker flexplate that I can't really go by the gaps l see other people run because they are measuring off of their stock flexplates?

lol Im so tired just wanted some experienced advice so I can torque everything tomorrow and get this over with...

thanks

While the Reactor flexplate is thicker than an OE one, it is not any taller. Meaning the offset is the same. ~0.575. The number you need to be concerned with is the distance between the flexplate and converter. You want 1/8 - 3/16. That will take care of proper engagement into the trans.

Ok before I torqued the TC down I had a 1/4" gap, so with using the 1/8" washer shown in my first pic that will get me right at 1/8" gap, sound good? Lol

So 1" bellhousing to TC pads doesn't sound too little?

1/8 should be good. The 1" bellhousing to TC pads is more of a check to make sure the converter is seated all the way. I think you are good to go.
