I agree with tossing the oil also, Lucas makes some very good items, but I do not like what I see here. Syn oil takes so much longer to seat the rings in on a new engine especially if it has hard rings. Myself I do a gallon of dino oil mix and then go to my Syn oil from then on.
Frank can make the rings for you W/O the piston and cyl if you have access to some precision Measuring tools and give him whats needed for sizes.
Everything else I have read here is about dead on to what my own thoughts are. I would put it together and run it and see how it pans out.
Good Luck at the contest.
