Yeah, best to use hardened keys or something like that.
But DO buy the full set of female square sockets.
MANY uses
Put a KEY or square thread extractor in them and it's stronger than a solid tool, and can also drive taps

Re: Valve Seat Materials
My understanding is the copper in the killer bee seats does not have much better cooling, rather it fills the porosity in the seat so that they don't shrink and fall out over time. I thought the same thing when they came out, that they might cool better, but at least as far as I know they don't actu...

Re: Unusual piston tops
Yeah, the carbon may not adhere well, if just run a short time and then stored. Looks like a snowblower, or something like that. Some of the seasonal use engines had extra clearance built in so they don't get stuck when the carbon falls off, LOL There is chemistry going on here, carbon can absorb wa...

Re: Lifters and compatible camshaft materials
I don't know, I mean, that's expensive cut a cam from a solid bar of steel. I'd think you would also have the budget to have somebody figure it out for you, if you don't know. No point having a cam without lifters, so, I would think that would be worked out early in the planning stages of what mater...

Re: Lifters and compatible camshaft materials
What exactly is a billet steel camshaft made of I wonder? it's not like there is a standard.
I'm surprised they even have a warning label.

Re: How centered does a piston pin need to be?
There is no universal tool that will fit everything, that's for sure.
Just when you think you've got it licked they invent a different piston shape.
The piston designers COULD do us a favor and make this easier but a lot of times it seems they don't even consider it.

Re: How centered does a piston pin need to be?
Good range of opinions, thanks, all. In the end after half an hour of "discussion" I told him to get out, and made a hand motion about which way the door is, and I feel really bad about that now, but, at least I'm being honest. Risk Vs reward, just not there, re-centering the pins on cheap...

Re: How centered does a piston pin need to be?
Lets put it like this, old american v8s, when you take the old ones apart, on the pin you see the two rings on either side, you can see if it was centered, and quite often they are visually not equal, but rarely enough to cause trouble. But as for why.. if that was the piston, or the rod, or the blo...

Re: How centered does a piston pin need to be?
I meant it as I said it, the pin needed to be moved about .050 Late model big block chevy. As far as I know, most people just eyeball it, and could be off .025, and you'd never know. But if there are people out there getting super accurate about it, I guess that's fine too. Tho I have concerns. Rod ...

How centered does a piston pin need to be?
How far off center is acceptable in your opinion for a press fit piston pin? I've just had a customer want me to re-do another shops work. The worst one was maybe .050 off center. You can guess what I said. But what would you say? He also thought you could heat the rod with the piston on it, but, he...

Re: One rod 10 grams heavier on big end
For the 90 degree engine to be perfectly balanced it would need very long connecting rods in the same plane, not next to eachother. So it's not perfect in any case, even if all the parts were perfect, so everything has a tolerance. Overall consensus is IMO, If the balance factor is between 50 and 51...

Re: Cam bearing hole
Exactly.
Fords work, so, it must not be terrible.
And far as chevy's a lot of them were built like that from the factory at one time, and they worked.
the new chrysler hemi is like that too, oops. LOL
