I just blew my TH350 in my 72 chevelle so I am planning on throwing in a rebuilt upgraded one. While I am at it I would also like to upgrade my torque converter but am not sure what stall rpm to get. I have a 350 small block bored .30 over with comp cams 268 camshaft, S/R 67cc torquer heads, an edelbrock performer intake, and edelbrock q-jet carb. Any recomendations on selecting a torque converter?
