Hello all,

Maybe I'm doing something wrong but....
When I try to install my new 3711 on my 350 (1975) it doesn't fit.
I can get the bolts in on one side or the other.... but not on both sides...
HELP

This might be a dumb question but are you sure it's a 350 olds and not a big block olds, got any pics?

 

Sounds like someone milled the heads

 

Yo Statti, here's a pic.

I changed the PS head gasket and exhaust man. gasket. so .....?
When I put the old cast iron intake manifold between the heads then it fits......

 

how can I post a pic?
I tried it with photobucket but not a great result....

click "go advanced" you should have the option to upload a picture, you might have to lower the resolution of the image to the required dimensions though, use microsoft word or something to do that then save the file locally.

this time better....

 

What are the casting numbers between the water pump and the manifold.

The BBO manifold is wider than a SBO

 

My 3711 did not fit when I used the end rubber gaskets. My heads were milled .010, but the bolts were not even close to lining up. I used RTV all the way around and I had no problems.

Take out the rubber end gaskets and silicone the ends. I had the same problem.

 

Make sure you have the right gaskets I had to get my intake milled 70 thousanths to make up for the .040 taken off the heads

THANKS !!!!!!
it seems to be the problem.
I think the new head gasket I installed is a tiny bit thicker than the old one.
