I haven't dyno'd my 318 so i don't want to comment on parts... but i am here to watch the 318 haters go off :)
BTW.. i went with trickflows on mine, the price is a little higher than other brands but i have more faith in that company to not send me garbage. Also went with Mancini roller rockers, they are made by harland sharp and were around $550 at the time.. i went 1.5 but they have 1.6.
No idea on cam, i went with a howards roller in mine and over-cammed.. it sounds amazing but not sure on power yet.
