not in my possession but the guy i bought iy has tripped the spark plug and got it help coiled then stripped and he got fed up, but ik the guy so i trust he is telling the truth, he did say it has to run premium fuel and what exactly needs to be set up nearly perfect? and are they suppose to be revers?
I don't really know myself what perfect is, maybe the guy telling me what I need to do only sees perfectly set up as the only way.
Flat top pistons and closed chamber head appears to be 10.9 to 1 compression ratio, when I told my machinist that number he made a face, that cannot be good as everything he has ever told me was true, he used to do mostly racing engines, and he would squeeze in work for me when he had the time, now he is doing normal machining for the public and when he retires the shop will likely close.
There is another thread on here, here is a link below, look at post 35 specifically, the guy made list in that post that mentioned everything I needed to do, and I basically replied with I didn't understand half of what he wrote, un-shroud the valves, time the cam at 107/108, re-curve the distributor, also lighten the flywheel which I did understand, I also understood some of the other stuff but likely don't really understand the extent of the work needed.
The L18 has been said to be a revver, but the fact is unless your on a race track it is not likely that any of us would drive it like that on the road, therefore we would not use its true potential and the only reason to have it is for bragging rights.
I built mine just to see if I could get it to run, I had just about every part needed in my parts bins, I am only out time and a gasket set, plus I intended from the start to use this engine to mock up a frame/chassis for my work truck, I want everything ready so I can just transfer everything without having to modify anything as that part will already be done(motor mounts specifically), I have done this a few times so I know what is going to need to be done.
