After a rebuild new everything..was wandering if I should start it up to break the cam in ...with or without the belt on the supercharger....
ThanksI would run it in without. You have added ~100 cubic inches and have likely changed everything in the motor
Thanks! I'm just trying to figure out the best way to go at this point this weekend. I'm hoping to get her fired up whichever direction I choose to take. I know with the old 440 it fired right up and would set and run wherever I wanted with or without the belt
If you can't pull a new lifter out of a fresh build, you should take the extra time to pull the intake, just in case.I pulled the valve cover off of the passenger side. I am able to pull the lifters up through where the push rods go in the head.on a big block. Without removing the intake. I've got three that are partial collapse collapse. And one that lost all of its prime. It's one of the three I can't get out of the bore. The magnet pulled the rest out. The two that were partially collapsed I was able to put in oil and pump them up solid. The other one. I have to wait on a lifter removal tool. Not sure why it's that stuck... I'm hoping it's not beat up on the end that's keeping it from coming out..... Is there any possible scenario that it was just lifters not pumped up all the way for whatever reason ? When I do the lifter across the bottom of another lifter there is just barely a concave on the lifter bottoms. On the lifters that I did remove the cam looked nice and clean. I'm searching for a silver lining here lol
That's what I was thinking...If you can't pull a new lifter out of a fresh build, you should take the extra time to pull the intake, just in case.
Chet hurbert....can't believe it would be that fragile lolWhat brand are your lifters. My nephew has a problem with new Comp lifters in his small block Ford,
that sounds very similar to yours. I have seen plenty of posts that question the current quality of their lifters.
Ouch !!So the lifter come out with not much effort using a little tool. The cam itself looks pretty good. What's a chance of just the lifter being bad?
I also check the oil and didn't see any shiny particles in it as the cam. Like I said, looked good. It's not rough or anything. I'm looking for a silver lining here. I guess I'm going to get a price on some hydraulic roller lifters and try it again
