    It's better when warm yes and not doing so much at higher revs

    I would suggest a session on the rollers is needed just to be on the safe side

    Yup. Hopefully in the next week or two will do that.

    Default Nova GSi Rally Car Build...16 years and counting...

    Lots since last post. The engine just never ran as nicely as it did before the cam pulley dowel issue. Carbs were serviced and rollers session suggested something else not right. Turns out valve guides damaged so engine out and the following done...

    Gates belt
    Gates water pump
    Goetz rings
    Secondhand Hepolite flat top pistons
    Glyco bearings ends and mains
    ARP flywheel bolts
    Elring Head bolts
    Elring top end gasket set
    Elring lower gasket set
    KS oil pump
    Torx back plate bolts
    Piper double valve springs
    Piper mechanical profile camshaft
    Piper followers
    Thicker spring platforms made
    Crank balanced
    Flywheel lightened and balanced
    Block skimmed
    Block honed
    Head skimmed
    Valves lapped
    Head assembled with new stem seals mechanical followers adjusted for valve gap clearance original followers, steel spring retainers and REC valves used.
    Block cleaned and painted, assembled using original ARP con-rod bolts, secondhand pistons fitted to original rods, removed most of dents from sump and painted, supplied longer bolts/washers for sump fixing, spacer made for timing belt back plate all timed up, standard pulley used (original was damaged) re-drilled to accept locating pin giving correct timing

    Compression ratio is now a far better 11.5:1 rather than the original 10.5:1

    The head is actually the Blydenstein big valve head I got off Boffer8 (Ben) some while ago, seemed like a good time to change things.

    Anyway all back in the car now. Will update after a session in the rollers again...fingers crossed

    Looks stunning. Curious as to what it'll do on the rollers once it's bedded in. 👍

    Should work a treat mate, good spec engine that now
    If Carlsberg did Motor clubs, then IDMC would probably be the best motor club in the world.
