I want to keep long runners, but the stockers kill 20% of my flow. I'm looking hard at the Edelbrock setup. They claim their runners are 1.7" all the way through. Anyone know if this is true? Can the stock manifold be made to flow with these runners? I don't know if it can lose the .2" of metal on each port. It sure would be nice not to have to buy a new manifold though.

 

i cant tell you for sure on the size but i did buy runners and base from edlebrock im sure ill get some different views on this but i love the look of the edlebrock runners jus my .02 worth
