Positive deck engine but the piston perimeter is right up against the head so too much rpm and one will "kiss" the other for sure. LOL. Weber and others were very fast, at the old HP, BEFORE porting. To me, with properly done heads, current cam and header technology, and the ability to run a lower class at virtually the same weight, it should be very strong. Since I have been away for quite awhile, there certainly may be someone running one now, but I am not aware of that. Perhaps you have knowledge of such a scenario. I would love to be enlightened as I certainly may have missed much along the way!


Thanks,

My son Jon Jr. runs one in SS/KA = 71 Duster 340 Thermoquad.
He can run with anyone in his Class out in our part of the World!
