your going to need new valve springs - just an FYI. thats not a recommendation btw, you'll have coil bind without swapping them

new string will smash your pushrods so u have to get new rods... strong rods and strings will crush you lifters so u need to upgrade those as well... u need a timing chain assemble and u shouldnt get a POS alphebet cam.... get u can at least better a better off hte shelf cam... i personally recommend jay allen for a custom cam... camshaft innovation .... he can get u all the other stuff u need... and like 77stang said he its not a suggestion its a requirement othewise ull have valve flow, push rods in S shapes, or holes in you lifters.... all of those will lead to more broken **** which will cost more in the long run... upgrade lift on a cam u gotta have good **** to bak it up.... more lift does give u more power if dont rite now... to do it right you looking at 600 bucks....

crazy im gonna have to disagree with you there bud.

stock lifters are fine, and the main reason people have to upgrade the pushrods are because they get guideplates and then have to get hard ones to prevent them from getting chewed up. with the cam selection he is making, the springs he needs will not be insanely stiff - probably something like 120 lbs of seat pressure - which is just fine for stock pushrods.

for the chain, you can grab a quality true roller cloyes piece for like 40 bucks. any more money than that and you are pissing it away for what your application is.
