Hello all,
I am new to the y block, but I put my first one in a 27 roadster I just got on the road. It seems the people that know these engines really know them. I finally got it going and it ran great...except for a little miss on the driver side. So here is my situation.
I have an eck 292. That I got out of a "running" car, the car was in a restored Thunderbird a guy was putting a 289 in...dont ask me why... it had been sitting in the shop for some time but he said it ran great.
When I started going over it I noticed it has been apart and I am pretty sure it has 272 heads on it but i can no longer find the casting number that I think is under the he headers now (i think it was ecg-d??...)
I got it going recently and it seemed to be doing really well but it had a miss that I started to track down. I adjusted the valves and my vacuum gauge was still wobbling between 15ish and 21 ish. It still had a miss. I tracked it down to cylinder 5. It was only reading about 60 psi on a compression test. So I put that cylinder at top dead center on the compression stroke and hooked it up to my air compressor. I did not get anything out of the carbs or exhaust. But air was getting out from under the valley pan near the push rods and the fill tube. I then realized that the head gasket on that side is on upside down (according to assembly errors websites) because the corner is sticking out towards the rear of the car. I am wondering now if these two things are related, or if I have two problems concurrently like, a stuck ring and a bad head gasket. I want to make sure I do not forget to check something when I pull the head. Also if I do have the 272 heads which head gasket would be correct? Thanks for reading this.
