which intake should i use?

I'm not sure what went wrong with the bullet cam ?
They make great cams that make great power.
bullet cam was a power maker, live in canada, and by the end of the purchase process(they sent a bb cam to begin with) i ended up paying 600 cdn dollars,400 usd, for a hyd flat tappet cam, no lifters, that didnt perform much differerent than the purpleshaft i had in it
