Dave_Mustang_50 2 Report post Posted January 19, 2006 Anyone know the difference between the 4v cleveland and the cj in 1973? From the factory, would these be open chamber heads? Dont have any numbers yet. I`m thinking of swapping out my 2v cleveland for this after a freshen up. Could I use my pertronix distributor and brackets from my current cleveland, or would they need different brackets. Thanks Share this post Link to post Share on other sites
