I have the same combo in my truck now. Sbc 400 30 over with a comp 270h cam and vortec heads and is putting out so were around 400hp. It is backed up by a th350 and a 3000 stall with 373s in the rear. And I have a friend with a 402 out of a 72 C-20 in his nova and we stay side by side. So I would put better heads and a bigger cam in the sbc it will be cheper. But that is just me.
