Hello all! New here...

Noticed the thread was getting a little off topic.
I have a 66 Nova with a 250 inline engine. I too have added an HEI, mild Comp cam, have an Offenhauser 4 bbl intake, and a Holley 390cfm carb. I was planning on getting the bigger 3 bolt 292 exhaust manifold and using that on my 250.
However, I called Stovebolt co. this morning and they tell me that the 292 exhaust manifold will only work if using the stock intake manifold?? Anyone knows what kind of clearance issues there are or if the 292 manifold can be modified to work? I'm curious as to how the 68 Nova Guys project is coming along, or if he encountered any problems with his setup??
