Help with choosing /6 build type for newbie

Bill it looks like you have put alot of time in on these slants. As far as transmission any suggestions. Also the suspension seems a paradox. The cars seem to ride so low as it is i couldnt image the car dropping 2 inches. I have looked at Hotchikiss TVS and simple mods from PST. I want to leave the factory 14s on her to keep the year look. Dont want to clutter thread il just pm you if thats alright. Thanks
