Hey guys, I have a 289 in my Ranchero that is pretty much stock, with 2bbl carb, stock intake and exhaust manifold. Ive finally saved up some money to start buying parts and ive decided to stick with my engine but just buy some new parts for it to increase my HP. (new intake, carb,cam,headers,ect) But how much horsepower will my block be able to handle? Also, I have a C-4 tranny, how much could that handle? thanx guys
