Hp I have no idea but im lookjng to buuld a really strong crew cab

 

Unless you already have those cams in your possession, you can do better. Absolutely not the 218 unless you want a peaky lowend torque curve. The 227/239 has a pretty big split for stock cathedral port heads but could work fairly well dependent on LSA and advance.

 

also considering the 222/226 eps cam

 

LS6 cam
74mm turbo
15psi of boost

 

Lol I won't mind the 74 and 15 psi but pockets not that deep lol budiet build
