Get Your Valvetrain Questions Answered By Nolan Jamora Of Isky

About a year and a half ago, we kicked off the cool series called “Ask The Experts” in which you, the readers, submit your questions to the chosen expert, and get the answers to your questions. This allows you access to some folks in the industry you might not otherwise have access to, while getting answers to questions that might not normally be asked.

So far it has been extremely popular, so much so, that our very first expert wanted to make a second appearance. Nolan Jamora – now the Chief Operations Officer of Isky Racing Cams – has a level of experience “in the trenches” that might seem surprising of a COO. He has worked on championship valvetrain projects spanning some of the highest, most prestigious levels of racing, to include Formula 1, NASCAR, LeMans, and Indy Car.

Most recently, Jamora and his team of experts have been focusing on some of the hottest types of racing, with Jamora personally supporting a number of Hot Rod Drag Week and Street Outlaws: No Prep Kings teams. “The cams for those applications are unique, and have slight differences from each other,” says Jamora.

If you followed our SEMA and PRI coverage, you’ve seen some of the newest Isky valvetrain products, which arose from their constant R&D in the latest emerging markets and technologies. Being on that leading edge, along with over 70 years of valvetrain experience, puts them in a unique position to answer pretty much any valvetrain related question you might have. Some potential subjects are:

  • Bushing vs needle bearing lifters
  • 4/7 and 2/3 swap cams
  • Valve lift
  • Valvetrain harmonics
  • Ramp rates and lobe shape
  • Modern cam design
  • Lobe center and it’s affects
  • Vacuum rule cams
  • Cheater cams
  • Parasitic drag
  • Correct break in
  • Picking the right cam profile for different applications
  • Turbo, blower, and/or nitrous cams
  • Marine cams
  • The differences between street cams, race cams, and “street race” or “true street” style cams
  • Any other valveytrain-related questions.

So type out your questions to Nolan and send them to [email protected] by March 29th (which is when the submission period will close), and then watch for his answers right here on EngineLabs.
