    metric nuts don't work on SAE threads. Why don't the rally lug nuts work? simply use the standard acorn lug nuts with the s10 wheels.
    Doing it all wrong since 1966

      I went around on this with both my '78 Camaro and Mutt (an '86 S-10). At some point in there GM switched to metric lugs and I now own a set of SAE nuts that don't work on Mutt 'cause he's metric. And the studs look almost identical. Basically, you'll have to decide if you have SAE or metric studs and get nuts that match. They should either be 7/16" or 10mm assuming they're like mine.

      In compliance with LSR rules I'm running 1" (socket size) nuts from Speedway. You probably don't need those big ol' honkers!

        What he said. Acorn shaped 7/16th right hand thread lug nuts. Available at any parts store.

          DAN, IIRC the g.m. lug nut studs are .12mm x 1.50 RH .Conical seat - 60 degree not 10mm..

            Thanks for the information. Next question for you folks... I pulled the cylinder heads off and found that the driver's side cylinder head gasket was leaking into the #7 cylinder. Surface rust has set up on the bottom of the cylinder wall. Scraping with fingernails didn't pull the rust away. I sprayed it down with WD-40 and plan to pull the engine for further investigation. Any recommendations for removing the pistons without causing too much damage? BTW, no ridge at the cylinder tops.

              PIcked up an iron manifold (3965577) for $10 at a yard sale. What recomendations do you have for removing or covering rust in the intake ports? As always, slow but sure...

                Finally got black lugs nuts that fit the wheels (thanks for info) and it is now sitting on the ground with 4 tires that hold air, for the first time in many years.

                Up next, I will replace the rear wheel cylinders

                  Quick update: I've been offered a free, running 350 (fully dressed) if I pull it. So, I'm planning to make the short drive to pick it up within the next month. Will update with photos at that time.

                          Unfortunately, I don't have vacation days or sick days available. The day for extraction is coming soon though.....

                            Much like life, this project has taken a few turns lately.

                            The engine I was planning to use is in approximately the same condition as mine, so I'm planning to pull mine and perform a re-ring rebuild; new cam, lifters, springs, gear drive, thinner than stock head gasket to raise compression a bit, etc.

                            I've been following along with Sloppy Mechanics (http://www.sloppymechanics.com/) since the turn of the year. Next, I found Project Joe Dirt (https://www.theturboforums.com/threa...-Megasquirt-II) and I really like this set up.

                            So my plan is to rebuild the current short block and start acquiring parts for a 4.8L turbo build...

                              Quick update: I've pulled the driveshaft, which I plan to paint and replace the u-joints. I'll be pulling the engine this winter for the rebuild and I plan to have the Camino running by the start of Spring. I'll give updates as the winter progresses.

                                Long time coming, but finally ready to pull the engine when time allows. Gave it a Comet and Scotch Brite bath yesterday. I'll update when the engine is out.
