question on 350 transbrake
 

Can you do a 350 transbrake with out having to get a special valve body?
I know 2 of the valves need filed down, and the case needs to be flat plus you need a solenoid to activate brake. Plus a few other mods, need to be done.Would be going in 71 chevelle with 13 to 1, 383 stroker motor 4.11 gears and 4200 stall converter. Thanks.
