Comp has a decent amount of info on their site but no instructions that I can find.

Also wondering if the oil band intersects the feed hole in the block with the Lifter down on the base circle. Would be nice if that were the case.

I just put a set in a new 3in main 455 engine.We found you have to pay attention and READ the DIRECTIONS!Once my builder did that they came right in and no issues on the run stand.Short version they have 150 thou travel and you adjust a 100 out.READ the DIRECTIONS.New Xtra cartridges are avail and ...

I am afraid of anything that is "latest and greatest" from Comp. I see what they are trying to do with the little description provided, but I am not convinced yet.....

I was going to go with the usual Morel 5884 and grind a slot for full time oiling to the band, and then my customer tells me he wants to run a set of Comp 85701-16 lifters with this new HCT technology. Can anyone please enlighten me here as to what this HCT is all about?

I've always broached then sunnen honed, I was never able to get the broaching to work out past a certain point, like the liner just doesn't want to grow past certain point, or at least enough to feel good enough for the valve to pass.

I still have PTSD from the time I did that one!!! Only air for me since then on most anything!

I worked on a pulling tractor head that was filled with bronze. Worked well and was able to turn the diesel ports into blown alky ports!! I imagine they had had to pre head the head to a glow before they poured in the bronze.

I called up there to Barrie Welding in December and they just threw everything they had left for the IDL stuff including prints into the dumpster 2 weeks previous! Makes me sick!!

I will buy if still available. Pm sent

Ok no rush... when you do find it I will take the #3 extension

Do you still have the #3 extension? If so I will take it.

If you want to do the repair on the cheap with the tapered pins vs using the locknstitch, just spin up a couple solid freeze plugs on the lathe out of 1018 or something soft, but steel or cast iron material. Install into the block and give them a thou or two press. Loctite them in before you start, ...
