As far as the rpm range of a 327, the sky is the limit. A properly built 327 will buzz to 7000 rpm or higher quite easily. As far as an engine with both torque and horsepower capability, the 327 is a great engine. Probably my favorite SBC ever.
Summit cams are cheap, but like John says, there are much better cams on the market. Cam technology has come a long way in the last 10 years now that they're using computers to design cam profiles. Save your money and go with a newer technology cam from a reputable company. To me, spending $75 more on a cam that makes more horsepower and torque is worth every penny.
Like it was mentioned, you have to be very diligent when breaking in a flat tappet cam with today's oils. The lack of zinc in today's oils will kill a cam quickly during the initial break-in. You must use a proper break-in additive, along with an oil that provides you with the most amount of zinc possible.

This is the kit I am looking at for a rebuild. I have not been able to find any information about the rod size/small journal, large journal. Any thoughts on the kit?
