    Can someone tell me if raised cam tunnel, wide pan rail blocks are allowed in x275?
    If so is it only for N/A or ok for power adder combos as well :)
    Thanks Carolyn

    2. ENGINE

    2.1 Engine transplants allowed

    2.2 All power adder engines must be of OEM configuration ( Ie: factory release Dimensions And conventional cylinder heads) Raised Cam, widended pan rail, after market aluminium blocks and tall deck blocks not permitted.

    Nos 400 this is what it actually states in the X275 section.

    Thanks Hewy

    That’s why I questioned it because both answers are in x275 rules ❓

    From what I read Widened pan rail and raised CAM is only for N/A also only for Small Blocks……
    Also Makes sense to allow these these for N/A considering you are racing against Power Adder for the same Class…..
