Steve, by comparing the 1" sq. tube, and I know the Vair case should be 7.875" in length, it sure looks like the distance from the firewall to the back cover is in the 8" ball park. what do you think?
I will try to duplicate Mikes mount as best I can. The engine case, crank & camshafts, are all boxed up waiting for UPS to transport them to Ultr Vair. I ordered their plan B package and they are going to machine and mount everything. I'll send my crank, rods, pistons to Scott for balancing after I get the engine back from UV. Real nice people to deal with. Did you know they make a four pound redrive? That would sure make the XL or LE hop up in the air. Hopefully by the first of summer I'll have a running engine, but I still have to do my heads, and all the other stuff, but progress is being made..
