85 Dodge 600 2.2 TII

Plans: 20lbs boost (TOPS, probably never get to more than 17. Only shooting for a 14sec 1/4), +20's, stock I/C, 2.5" exhaust, stock T3 turbo.

Later in the week (whenever I get paid for the van I'm selling ) I'm ordering a new tranny from Cindy with extra clutch packs, modded valve body, line adjustment plug, drain plug.

My question, do you guys think I'll need a Heavy Duty converter for this pig? I don't plan on making a serious amount of power, but I did destroy the shiz out of my stock tranny with 15lbs boost. A HD converter is 350 bucks + shipping whereas a stock one is about 100.
