Well I think in this case its the Comp cam.....and high rpm shifts. I had a 100000 mile OEM pump with a beauty gear on it.....not HV... I never wiped out a cam in any way till this year. I killed a Comp cam in my work truck this spring as well.( 3 lobes) This motor has about 1500 miles on it DI....and its already wiped out 2 pump gears , a crank and a cam. Yood think I had it on a bottle... Thanks for the cam offer Dennis...Im not sure .510 lift(.340 at cam) is doable with low CR(9.25) and my old chev valve springs. I might preload a rocker 47 thou and see......(currently .440 lift......293 at cam) The good news was the car top ended like never before..... |

Sandy IIRC I saw a post that ERSON has the 270 " on the shelf for 1 day shipment" It might be the ticket for you. On a side note if you get to Arkansas we are 18 miles off of I40 @ mile marker 221. 1 hour west of Memphis Tn. Frank |

Hey Sandy when you tear it down, let me know if you see any evidence of cam walk, I forget if you are running a cam button or not on the timing cover... I'm wondering if this is a fair part of the issue. -D.Idiot |

No cam button. Ill look for cam walk.... Its strikes me as significant that I never did a pump till I cammed it. Having wiped out a Comp cam in my work truck this spring Im not very confident that the Comp cam pump drive gear is not at fault. I wont have any time to even look at it for a few weeks..... |
