Default what size circle-D converter? 150-225 shot

im working with alot of weight here. 4500 lbs race weight.

LS1, patriot stage 2 LS6 heads, ported Fast 90mm, 231/239 .617/.623 111+2 cam, 4l60e, 4.10 gears and all of the typical bolt ons that you expect.

the truck is a toy at this point. it does see street use but only on the weekends, or the occasional friday to work. I drive it to the track too.

i currently have a fuddle 3600 converter. it only brake stalls to 2300rpm or so before spinning the slicks....but on a 125 shot out of the hole im cutting 1.67 60' times and trapping 118mph. i have been impressed with it. before the bigger cam and ported fast 90 i was cutting 1.69 on motor.

im thinking about the 4c tripple disk, but i dont want the nitrous to go through the converter. the biggest shot i have planned is a 225 shot. possibly 2 stages or progressive. i want some 1.5x 60' times out of this pig.

sooo my best option is a 3 disk 3c or 4c and why?

how much should i expect my mph to drop over the fuddle?

I would call Circle D and see what they recommend
