After I installed the 261 engine I had to extend the transmission linkage. I thought that maybe we bent the rod during installation so didn't think much about it at the time. I then noticed that the top of the air cleaner was hitting the underside of the hood and when I checked underneath I saw that the oil pan to idler arm clearance was much more than before. I checked the distance between the top of the motor mount to the oil pan rail and it is seven inches (same as the mounts on the 235).

Is there something obvious that I am overlooking here?

Thanks, Pete

What motor mounts did you wind up using? Can you take photos?

I used the towers that were there for the 54 235 and used motor mounts from Davis Speed shop. As I mentioned before, the distance from the top of the Davis motor mounts to the top of the oil pan rail on the 261 is the same as the top of the mounts on the 235 to the top of the oil pan rail.

Thanks for the response, Pete

So the transmission and driveshaft are installed and look right, but the engine is just sitting high?

When I installed a 261 in my '53 I located it too high the first time too. In my case I made my own motormount brackets and just made the first set wrong. Second set came out right.

Question: Can you remove the valve cover and reinstall it easily, or does the firewall bulge into the pass compartment interfere with the end of the valve cover.

You might take a tape measure and measure from the engine mount pads on both engines, to the top of the engine, then from the pads to the bottom of the pan. I don't remember, but the two engjnes might be different heights, or, the pads on the blocks might be in different places.

Make sure the mount pedestals are the right height as well. I realize you are working with an I6, but GM used different pedestals for some of their engines in the later V8's, might have done same with some of the b's too.

I used Davis 261 mount in my 54 and had similar issue I emailed them and they were very responsive. I trying to remember what I finally did to fix it and think the issue was how the transmission was sitting. I do not know if it put the solution in my post but I did post asking for suggestion. You can look for my post.
