408 stroker cam recommendations

Plenty of engines were built right from the factory whose cubinc inch displacement began with a 4 that used what most would consider crappy, poor flowing heads. Some of those "4" engines have been the most torque producing engines the factories have ever made.

That said, if you are going to run the stock head, it surely wouldn't hurt the build for you to save up and have the heads professionally ported and larger valves installed. It would make a world of difference.

But, if you cannot afford that in a reasonable a mount of time, simply be CAREFUL with your camshaft choice. With the heads left stock and as a "cork", you will need MILD camshaft choices. It will be easy to over cam, so keep that in mind. Cam it like it is a 360 and you will probably be very happy.
