Need suggestions for a convertor, please?!

[6pack]

Putting a TH-350 in my Buick and Tranny I bought has no convertor and I would like to know what you guys would suggest as a convertor. Car and mods are listed in signature below. Thanks!

sounds like a fairly stock app id use a 11 inch because you lost multiplied torque applied to the rear wheels by installing a 350 w/a 2.48 first gear as opposed to the 2004rs 2.75 .an 11 inch rated at 3200 should stall at 2600 to 2800 behind the 3.8 .this should help accelerate the car fairly well and still allow the convertor to hydraulically couple around 5200 rpm when thrashing it .we sell one for 249 bucks .www.ckperformance..
