Does anyone know what a good compression ratio for a 347 NA street car would be.

RE: compression ratio

It depends if there will be and other power adders on it . I currently have 10.5 to 1 on my 347,that built at DORD PERFORMANCE SOLUTIONS! My moto is naturally asperated. Plan on uaing a progressive N2o system on it. Give the FPS builders a call at #714-773-9027 ask for Troy (the owner) and tell him Sergio told to call them up. Very nice to deal with,great customer support too!!!!!!! Good Luck!!!
