cheap cam upgrade for 86 4000Q?

[Dave Glubrecht]

For under $100 you can buy an adjustable cam gear.  This allows you to move
the troque peak higher in the rpm band and get some bennefit from the stock
cam.  I am not sure how much gain you will see on a stock motor, but I am
very pleased with the results on my 10-1 motor that also got the exhaust
opened up and a minor port and polish job.
