Why not piston installation before headstuds?

[efhughes3]

I'm wondering: why can't you install pistons before you put headstuds in? It seems like every photo I've ever seen shows studs before pistons. I'm aware you'd need to be careful and not bang the skirts into the case as you make the revolution when installing the pistons, but it seems like not having to work around the studs would make the circlips easier to install?

Why wouldn't this logic work?

Well, let me think this through. You have to put loctite on the stud tip and insert it into the threads, then tighten it down and measure the distance from the case. I don't think having the piston on would hurt, but you'd have to find some way to keep it from flopping into the case or banging the skirt on something. At least when you have the studs in you can suspend the rod with a rubber band so it's more or less in the center of the spigot when you go to put the pin in.

Here's one for you, are you going to use a tapered ring compressor and put the piston in the cylinder on the bench BEFORE you insert the pin, or going to use a HAZET and put the piston on the rod, then compress the rings and slide the cylinder over the piston?

The second route: pistons on rods, cyls onto piston.

When Supertec head studs are used there is no need for stud installation measurements.
Top qualty, easy of installation and available from our host.
What could be better?

How about a lower price hehehehe *poke Henry in ribs hope he laughs* How many more would you sell if they were closer to the OEM costs? Could you make up the margin losses with volume?? Of course, this genius market snatching move would be great... and I have absolutely no bias

Each way has its +'s and -'s. Perhaps the method has been set by the factory and most have not seen fit to alter it in the manner you suggest? Try it and tell us about it

Best regards,

Funny you should mention that, these are what I'm using!!!

As the builder of a "few" engines, have you ever done it this way?

You may be a little confused: If we sold a few more sets we could lower the price because we could order more inventory with each run making each unit cheaper.
Be a giver. Work with me for those Pelicans who follow in your footsteps and start me on the road to lower prices. It's the unselfish thing to do.

Well, I put my money where my mouth is....was going with ARP's, but came to my senses and went with Henry's set. When you run the numbers, this isn't crazy money at all when you price out a complete set of new steel, nuts and washers.

That's the same conclusion I came to Ed... pretty sure I get a few extra HP from them too... j/k

Plus, they look great listed on the build sheet!
