I am building a 327 for my 55 chevy and I wanna run a Duntov 30/30 camshaft. I see the lift is .455 and the duration is .253 at .50 with a 114 degree lobe center... Has anyone run this cam on the street? Can someone give me some info on how it performs? I am running a Muncie 4 speed and a 3.55 rear. I would think with the duration that it wouldnt start howling till the rpms got up with with the lobe center at 114 I would think that would help. Thanks much.
