yes John mine have a gap about that amount and it scared me. I'm going to pull the trunk lining out of the 36 to get a good look at things. I'll take my camera and get some good photos instead of my phone photos. I was lifting on on the rear corner of the C-2 trying to decide if flexing or bending was going on, it was a very crude experiment with nothing to report.
I was on a mission today, when I got my AACA magazine I started going through it back to front. One of the first things I see is a 39 Chrysler 8, rebuilt, $400.00. I couldn't get to the phone quick enough thinking for sure I was going to get a "sorry it's sold". Today I picked it up, (had to drive about 500 miles with the first 40 miles on snow covered roads) but it has a perfect exhaust manifold. I didn't get to really check the engine yet I got home in the dark and the engine is still in the back of the truck, but the manifold rode inside with me. It's like winning the lottery!
The 39 C-23 engine has the different style water pump.
Can this engine fit in the engine bay of the airflow with this style pump? Hopefully the C-2 aluminum head proves to be usable and I believe from what I read it should fit the 39 engine. I read the article on how to modify a newer head if the C-2 head is no good. I should be able to configure any special piping as I was once a pipe fitter.
Will I be able to mount the Airflow dampener and fan from the C-2 engine to the crank of the newer engine?
That's all I'm going to ask now because I don't want you to get mad at me!
