One of the guys over at PY just responded with this chart for selective fit pistons for 1970 and 1971 Pontiacs. Looks like I was right!

Visited Roger's Automotive again today to drop off a spare flexplate in case they need it for the balancing process. Gotta love that Safest Rust Remover/Evaporust stuff. Two hours of soaking cleaned up the rusty flywheel nicely. (I degreased it completely first).

The balancing of the rods and pistons are done but they are waiting on the crank to get back from being ground. Good news was that both the rods and the pistons had less than a gram variance between each individual piece. So very little had to be done to them.

Since we will be adding a bunch of horsepower to the car I figured it was time to install a tachometer to keep an eye on things.

I did not want to change the dash in Gramma's car by installing a Rally gauge setup with tach because that would require a complete dash wiring harness change along with a ton of other items. So I decided to go with an old school tach I had sitting on a shelf in the garage.

I have had this particular Sun Super Tach II for at least 30 years and it has been in over a half dozen cars of mine in that timespan.

I also did not want to drill a hole anywhere in that pristine dash. And of course there is not enough room on the column for the old school hose clamp over the bracket installation as the turn signal lever is in the way. In addition, the majority of the lower column moves due to the functioning back-drive linkage that locks the shifter in place when the key is removed.

So I pulled the dash fascia and located some existing mounting screws. I then use some bodyshop hammers, a vise, and an anvil to hand-make a mounting bracket that extends out under the dash overhang. I located a vintage flat mount Sun tachometer bracket on ebay for $11 and drilled a couple holes in my handmade bracket and voila, the tach sits very nicely in view. It doesn't block anything behind it other than an idiot light or two, and it looks rather 1970's nostalgic.

My Franken-bracket:






And the installation. The drop down distance of the horizontal bracket is just enough to keep the two mounting screws from touching the underside of the padded dash.

Nice work!

BTW, if you look at the above photo through the windshield, sitting by the woodpile, you will see two NOS 15" studded, whitewall, radial, snow tires. Is anyone building a vintage 1960-70's station wagon they could use them on?
