Trust me, a lot of weight needs to be removed to get where you want plus it is trial and error. The small weight raises part throttle and the big weight raises full throttle, I believe. I have mine shifting at mid-high 4000 rpm's with the green line bias spring from the big Trans Go shift kit, raises shift rpm by 300 to 500 rpm and shaving the weight a bit. For a torque converter, contact PTC and ask for the same converter as Dan Mascal uses. A 2800 stall 10" tight around town for around $400. Dr Dan as he is known on ROP was a GM tech for years and actually builds the 2004R for himself and others and knows how to make them live behind Olds sledgehammer torque. He also runs Olds 403's very fast using Qjet's for carbs as well. I have the cheapest PATC 350 hp converter rated 2200-2500 stall, tight on the street and flashes at 2300 rpm behind my 350. I plan on using a staked with a screw Monte SS or GN governor, the spring has a tendency to fly out, upgrading my extra pump to put out 250+ psi vs my current 215 psi and getting the Dr Dan converter. I am upgrading to a 217/223 custom cam in my Olds 350, should be much better than the lousy, too small Performer cam. I am also planning on 3.90 posi and maybe a Holley sniper in my Olds Cutlass 70 S. But for next year, it will be Dr Olds mileage machine with an Olds 260 with mild mods, dual exhaust with a H pipe, open top air cleaner, Startus electric fans, 88's current 2004R with braided cooler lines and 2.78 gears. My 88 CSC will see race duty, stripped interior with 424 Olds stroker 403, TH400 and 9" with 3.89 locker eventually.
