Best, least expensive, and easiest way is to buy a 289/302.

not gettin on you but its an inline six not v6. other guys will do so if i dont. you can look athe two barrel induction wit the modified manifold or adapter and get the headers with splitter that seperates the exhaust into two pulses not one and it scavenges better. truthfully you wont get crazy power out of it but you can get one fuel efficient street perfprmer out of it. you want real power go v8.

they have some stuff for the engine. theres options like the aussie heads but they need machining to work but they work great. true dual exhaust too

you can make those sixes scream.

check out www.fordsix.com and www.classicinlines.com and to answer ur question the best way to achieve the most possible power will be a turbo
