Camshaft FAQs

Questions about your camshaft? We’ll be happy to answer them! Some of the most common questions we get are listed below.

Can a cam be “too big”?

Yes, depending on compression ratio, tire size and rear end gear ratio.

Do you have to change valve springs with high-performance camshafts?

In most cases, yes. Be careful, depending on the lift of the camshaft, that you have proper coil bind clearance and valve retainer to guide seal clearance.

Flat tappet camshaft failure

Recent changes in oil and engine technology are likely the cause of most premature camshaft failures. Besides proper camshaft set-up and break-in, it’s important to use a good camshaft break-in oil additive to replace the reduction of zinc and manganese in today’s oils. Competition Cams, CraneCams and ZDDPlus are some of the suppliers of such additives we use and sell.
