i am building a sbc 350. i purchaced the new edelbrock performer eps intake manifold and installed it. my problem started when i went to install my accel distributor. i noticed a considerable amount of slop between the manifold bore and the distributor flange. upon further inspection i discovered that the manifold bore checked at 1.437 dia. and the distributor flange checked at 1.247 dia. whats going on here? is this a normal thing? i have talked to serveral guys about this and nobody seems to be aware of this. i have seen bushings offered by mr.gasket. is this something i should be using? i went to the store where i purchased the manifold and explained to the owner what was going on. he told me has been selling edelbrock manifolds for quite a few years and never seen it or heard of it. we checked all of the manifolds on display and found the samething with them. does anybody have any ideas.
