My 250 and the 292 I'm buying both have separate manifolds. Also I recently rebuilt my Rochester B. My truck was originally equipped with a 292 and based on what I've read the numbers point to it being the 292 carb.
I've heard of the exhaust manifold issues but I kind of want to stay away from headers. Anybody out there know WHY the 292 heads ran hot?
And yes the motor will be worked very, very hard haha
