Fascinating. Thanks for taking the time to document your project. Are they all removed as a single unit? Is there a concern for thermal expansion? Quite the undertaking, far, far beyond my abilities. How many times did the block go in and out?
Husker,
each bank is a single unit like a conventional under car header where the 4 pipes are welded to a flange. They come together and the collectors slip on.
I had them tack welded to the flange so I could remove the individual pipes to solid weld the joints. After I finish that then I will hard weld them to the flanges.
I am not concerned about expansion, the system has plenty of room to move.
The engine never came out of the car. The whole thing was built inside the car. The pipes never came out of the car either until the whole thing was tack welded then they were removed.
I saw it outside for the first time when I bolted it to this engine on the dolly.
The mock up engine is still in the car. The engine on the dolly is another 400 block and heads that I have laying around.
We all have individual talents to contribute on this forum. Thats what makes it so awesome. I love reading other peoples build threads and the ideas they come up with. Currently digging MacMans hood vent thread. Very cool.
Quite a Brain Trust here on the PIBB.
