Still wrong; in my opinion.

Regarding the steering box, I see that Stoddard has new ones listed.

Regarding the push rods, I think Chuck Forge was using some cut to length after market pushrods. Vic, do you know about current sources? Seems like a simple solution.

Some interesting reading

https://www.engineeringtoolbox.com/line ... _1379.html

Not sure if I get it absolutely correct on this but as a start.
Eg 6 inch long cylinder in cast and delta temperature 250 degrees C (cold to hot)

Cast cylinder would expand to 6.0161 inches
The alu rod would expand to 6.0345 inches

Thats a 0,0184 inch difference, or 0,046736 mm and if valves set cold at 0.15 and 0.20 mm this could give very tight valves at hot engine.
Rod is somewhat longer but head is alu in Porsche world, now the cylinder bolts are steel but maybe they just stretch with the assembly.

CSP have reasonably priced rods

Not much happened with the car last month but I have been off to the US east for work & west for the holidays.

I had the pleasure of meeting a few fellow 356 members in Tustin CA for cars and coffee, here we have Rich and Bob if I rememeber correct or maybe it was Santa Claus and Bob.

Peterson Museum, lots of nice Porsche's but best of all were the Bruce Meyer Ferrari's (250 TR and 250 SWB), so nice to let people walk up and even peek inside these $$ cars.

Had to get something better than a KIA for the roadtip to and around Las Vegas++, the Camaro was nice if somewhat limited vision.
