  1. John Munroe

    A couple of comments/suggestions regarding the rules for Super Stock:

    Suspension – Mandate stock lower front control arms but allow IMCA spec tubular uppers. They are not expensive, are stronger than stock upper arms and make adjustments easier.

    Frame – Allow frame height at 6″ instead of 6 1/2″

    Engine – The rules for heads and intake can be confusing. Do you really have to take a 100lb penalty and use a cast iron intake for Vortec heads?
    Also, under Engine section 8 it says: “Intake must be strictly stock and case iron” Then later “After market aluminum allowed $200 claim rule”. For the intakes I suggest allowing stock iron intake (weight break?) or specify a dual plane intake or maybe any aluminum intake.

    Are straight plug Dart Iron Eagle heads considered production?

    Thanks and look forward to the 2016 season.
