7875 + 5.9 + E85 + Megasquirt
New converter installed. Got this from a buddy who had it as a spare. It’s a Circle-D supposedly and was built for an oddball — LS turbo mated to a 727 in a Dakota. It’s a little tighter than my PTC and has much better street manners and flashes to about 3200rpm. Now that I’m able to couple the HP to the trans and back to the rear tires, the difference is incredible. Feels like I was slipping 100hp in the old converter. Oh, I've been using Hygard (Lucas equivalent)
@TT5.9mag for a while now on my trans. I love it. Just add enough ATF to give it a watermelon juice color so you can read it on the dipstick.
