I am looking for a cam for my 350. Currently installed in my '68 bird is a '71 YN Block, #94 heads (long story on the dog motor...), '68 GTO 4bbl intake, T10 tranny and 3.55 rear end. I will be installing #13 heads. I like the 068 cam, but have also looked at Summit cams #2800 and #2801. I am concerned that the Summit cams might have too much lift for my application. I will probably run the new cam while the #13 heads are being built. 2nd question, will my current push rods work, or should I invest in the p. rod length checker?
