VALVEBODY QUESTIONS WHICH ONE

I have my mind set on a lenctech valvebody street terminator. It has 1,2,3.and overdrive lock out via electric switch,its 399. I just opened up my ford racing catalog and i saw the same valvebody but its only 329 plus i get a discount cuz my mother in law works at a ford dealership. So should i just stay with the lentech , i dont know of the quality of the ford piece. but they are both the same with the electric lockout no 1d1 shuffle. what would u guys do. ALSO im pretty sure i want an nonlock up converter but i am afraid it will make the car feel slower just need some reaasurrance that i should stay with the non lockup. Engine is in sig. I will be spraying a 100 shot on this so i dont know if that will affect ur input.

wont i be snapping shafts tho. i was told even with the hardened shaft that it will be too much power on the 2 to 3 shaft and it would never last. and that a nonlockup would faster due to the engine freespooling as compared to locked, for instance in my buddys cutlass he has the electric control so he can control lockup but if were doing like 45 and u floor it with lockup on it takes a lot longer to go faster as compared to doing 45 with lockup off and flooring it, the engine shoots up to a higher rpm and climbs quicker. also i was told by art carr that a nonlockup would be quicker in the quarter because it would act like powershifting a stick. What i mean is that the rpms would stay higher between shifts as opposed to dropping when u hit second or third because its locked.
