Ok guys need some advice and guidance, I'm swapping my 203 for a dana 300. I never really liked the 203 there big, heavy and a pain in my ass. My chassis is a s10 on a 1/2 ton frame, four linked front and rear with locked tons and 38 inch tsl's. the motor is a sbc 350 with flat tops and vortec heads and small cam, with a stock th350 that has a small stall. I'm using a np208 adapter off a 700r4 to adapt it. Will a stock dana 300 hold up to this setup or will I need to completely the shafts or anything else some help would be appreciated thanks.
