340 cam 1000-5800 rpm... torque converter

318, high compression with purple 340 resto cam in it. 3.50 gears 28" tire, what seams to be a good street / performance playtime converter to be used in the combo, all the other engine goodies there too. I spoke with paul at turbo action, awaiting e-mail or call back on pricing... suggested 19802st for my application. is his the better choice or would say like hughes 27-25 be a better option, looking to spend 300-500 for the right one.... want to be able to drive it. everyone is saying 2500 rpm is the te righ tone, seam a little high? but I may be wrong, not used to 3 spd autos, used to electric overdrive lock up models... looking to do it once and for get it. any thoughts?
