Default Torque converter gurus, help please.

Late 1986 L98 w/ mildly ported alum heads, ported upper and lower plenum, but with stock runners. Standard bore 10.5:1 flat top forged pistons, 216/228(at .050") .454"/.480" 112 lsa, stock 1.5 rockers. Shift kitted rebuilt 700R4 and 3:73 rear end.
Is a 2600 stall speed lock up converter too much for this set up? The car isn't a daily driver, but it sure isn't a race car, so I can compromise a bit on the streetability. Is there enough motor there for this, or should I go down to a 2400 or 2100 stall speed converter?
Any help would be greatly appreciated. Thanks.:)

Your stock stall is rated at 2024 rpm, so you can use that as a reference points. The more expensive TC have better drivability also.

Thanks Radpolo.
My trans builder told me that I really don't want to run anything higher than a 2600 stall speed converter. He says that the trans will feel like its slipping all the time below WOT. True?
Anyone else? Thanks.
