Yup... I ordered mine from Gwatney and got 5 or 10% off. They are a dealer. That's the same one I got and they did the dual bolt pattern. It's a super nice converter

Not a stupid question.... Get ahold of Chris or Glenn @ Circle D and see what they suggest. I got the 265mm Pro Series Triple Disc. 2,800 stall in the 1A Stator combo (for a tight stall in a heavy truck). I got mine from GWATNEY Performance for $1175 shipped direct from Circle D. They do one free stall change or repair if you blow it as many of the high end companies do. I considered others, always came back to Circle D. Nothing but great things and service from them.

I didn't know about the 1 free stall change or the free repair. Do they also only do that once? I bought mine through the garage that did my mods.

now why would I need to replace the stall?

They do one for free if you break it or simply want it tighter or looser

Just in case you break it or decide you want a looser (higher) or tighter (lower) stall. You want it as tight as possible with these blowers since they make so much torque down low.

You want to spec your stall to the cam. The idea is for the stall to be 500 rpm above where the cam starts making power. I had a 26-2800 circle d and liked how tight it was, but at times it felt too tight. I went to a Precision Industries 3k billet triple disc (5yr warranty, free restall within 1st 2 years). It gets into the power quicker and is slightly looser, but I like it.

Also you want to spec a PD blower cam with less overlap. U don't need a big cam for forced induction application. My Vinci trucker cam is real close to the BTR stage 3 truck cam specs but i have a 6.0 and it's a blower cam. What works in a forged 402 may be a big cam in a 5.3. It will be weak down low and you will need to compensate with more stall. No amount of tuning will help that.

It will be much easier to work on, plus might as well inspect cylinders etc.

This is an amazing thread! I get a queasy feeling just thinking about the cc statements, im sure you know the fed ex/ups by first name at this point? Come on man, put the key in the ignition? We are all getting anxious out here!
