i have a 1970 429 so i have been reading the forums and some people state they came with 360 hp from factory what can i do to my 429 to gain alot of hp? i had an aggresive cam kit, should i do aluminum heads? roller rockers, bigger valves, headers, high rise performer rpm intake. i'm stuck idk if i want to just rebuild the 429 and try and get as much power as i can or go with a stroker? I would like to be able to run 91 and make it a street/ some strip truck.
