These are not for the faint of heart. These are the biggest cams BC offers for our 4g63. These are in pristine condition. They helped achieve 605whp @ 27psi and 650whp @ 32psi. These cams wouldnt have a problem cracking 700whp @ 36psi on a 67mm 4g63, on a completly stock port head. They sell new on extrempsi for 390 bucks..I want to move these FAST, I can ship these out tomorow. Asking 325 shipped!! I will get some pictures up later.
