is this the stock motor for that car , because i dont think it is 340 was only offered to the cuda in 73 , if im wrong let me know , now with that 340 i would stroke it 416 stroker , cost about $1500 or the kit , and then edelbrock heads 557 purple shaft cam , 850 hp holley ,,,,, http://www.hughesengines.com/ best place for the killer parts and some serios hp for the small block guys , or just nos would be a nice way to have some fun , and another thing if the 340 is a cast crank , just find a 318 steel crank , same crank , 509 purple shaft is a killer cam and flow out your j heads with flat tops would be a killer set with a victor intake
