#8 Piston hitting relucter wheel?!?!
Just got my motor back from the machine shop and started slapping stuff together and last but not least after putting in the #8 tried turning it over and seems the #8 skirt is hitting the relucter wheel, in the process of trying to find out the point of impact i guess the spot was nicked off and is turning over fine.....My question is should i send this back to the machinist and get the skirt clearenced/balanced again? or can i run it? my guess is at higher rpms this could be a problem, crank is a callies and pisons are diamond

Who is the builder, you, or the builder? Is it a stroker motor? Strokers need the #8 piston clearanced for the reluctor ring. That is the builder's responsibility. I think you must be calling the machinist the builder.
That little bit of aluminum won't make the piston need rebalancing. You should clearance it a little more than what it is now, I don't know how much though.

Sorry meant machinist, I'm building it lol, yah I need to find out how much clearance I need from the Relucter to the piston skirt, if it's not much at all I can grind it or file the skirt down a bit and yes 408

Well he's a recommended builder by a good friend, supposed to know Ls engines, I'm sure he will correct the problem but I hate making that drive 1 1/2 away lol, if it dosent matter where the clearanced piston goes and I can take a small amount off in the area affected and still be reasonably balanced that would be wonderfull.... He numbered every piston for me and this is my first time building one myself, on top of all this madness I also ran into the double timing chain/melling oil pump deal where u gotta grind some metal off the front cover!

I'm using diamond pistons, I called em and they said that the cleareanced piston is within 3 grams of the normal, so I took it back out after briefly looking for the correct cleranced one and not finding it! It's prolly in the motor just hard to tell which it is due to small difference....I just ran a file over the spot that was hitting until I had good clearance, it did not take much filing at all
