ok i started with an idea of buggy w/4cyl.,&toy axles, now i have decided to do 60's and a 4.3 v-6. Will a turbo 350 be enough tranny for it or should i go for more beef? the only reason i ask is cause the turbo350 is available. i would like a 4 speed auto that i can manualy shift they work very well and are plnt strong, but a bit spendy right.
