I've started a new thread to provide David Vizard article link on Hot Rod magazine. Excellent article which I am sure many of you may have read. If you haven't its well worth the read.

FU,

Its principally about an SBC BUT it has a great deal of valuable information about developing the right specs for optimizing the cam/cylinder head combination. Know anyone who has the flow numbers for the LT-5 heads?
I'll post a sample of the cam specification when I ran the TFS23d head airflow numbers through a the Vizard calculations. My suspicion is that with a good exhaust system, there's good reason to run a single pattern cam profile on the LT-5 or possibly a smaller exhaust lobe.

No flow numbers, NO cam spec! YOU COULD be in the 10's, but never mind.
