1967 LeMans project

So, car arrived two weeks ago. Much better than expected since it's ebay purchase.




All original car. Never touched except few rattle can touch up's. lol
Engine is out, disassembled and in machine shop. Plan is to go 20 over with cylinders, 4bbl intake and carb, disc brakes, manual trans etc.
Parts are already here so I,m waiting for machine shop guys to be done. I have big pile of everything new around engine.
Few patch panels, couple of dents and car will go, probably, dark metallic green. It'll be fun project so stick around.
Oh yeah, and I'm doing everything myself since I build hot rods for a living.

Looks very nice, a great project car. If you built rods for a living, this should be an easy, fun project. I assume your LeMans has a Pontiac 350 that you will be rebuilding. Are you going with a 4-speed or something with O/D?

Keep us posted on your project, pics are always appreciated!!

Engine is original 326 with original powerglide. Machine shop guy called me with great news that everything will clear with .20 over.
You have a point Pinion head. I looked up online and I couldn't find .20 over pistons. I did look for 10min lol

This helpful tip may or may not be relevant for your build.

The two-speed transmission in your car is not a powerglide, it is a Super Turbine 300 (ST300).

Completely different unit. It's actually a quite nice unit. You might be surprised how well the cars run and drive with only a two speed transmission.

Good luck with your build, keep us updated with pictures!

Oh thank you for the info. Guy that sold the car said it's all original with two speed automatic. i just assumed it's powerglide as I'm not mechanic or american My thing is metal shaping, body and paint. I'll talk to my transmission guy and see what he can do for me with this one.
Here is a picture so thread doesn't get all text

Very nice..looks like a great project car. El Monte Slim had good advice, before spending $$$ on the trans, try the ST300 to see how you like it. It's uniqueness may win you over. If, however, it does not win you over, a BOP TH350 is an easy swap to replace it.

My brother had an ST300 in a '65 Olds 442, but he tired of it and put in a TH400 which he loved. Anyway, like paint--it's your car, your choice.

Glad to see you keeping the 326 as most don't. The 326/285 HP was the "HO" version.

I see the "scallops" cut into the top edge of the cylinders. Was this factory or did your machinist do this for the installation of larger valves?

No, those ''scallops'' were there from factory. And heads are open chamber. I think this engine is 250hp non HO version but I also don't know anything about Pontiac engines lol
Picture is when I just took it apart.
