    Should look into milling that divider down 10-20mm. It made pretty good gains on the new Edlebrock manifold.

    The Harrop is a totally different manifold to the Edelbrock AG with different runner layout which are shorter with less cross section (read: less volume) plus a smaller plenum.

    Pretty dangerous suggesting to just copy what worked on the Edlebrock hi-rise dual plane may (and probably) won’t work on a low-rise dual.

    The only reason Wayne milled out the divider was to correct the lean left bank (by balancing out the plenum pulses) which was determined with a fair amount of dyno time.

    now i know how much you like this seeing as your washing it by hand not putting this one through the automatic car wash?

    Never quite understand why people wash their pride and joy in those ‘hand wash’ places…

    The harsh chemicals they use are just terrible for paint and the car wash ‘brooms’ are coarse and always full of other peoples dirt and grit…

    Nice work Doz..  Actually fairly decent results for fairly mild combo.

    The low comp kills these engines and the stock manifold ensures it.

    Doing a very mild VR304 into VK Calais as we speak so interested in these results.

    The 268 cam is a baby cam.  The original tune would be fine to run it in on but as suggested, far from ideal for driving.

     

    Doz – how did you find the 284 with the bananas?  What comp?
