Small Blocks.....so much hp, so little weight, so little size. It isn't any fun if you can change out header gaskets in less than 4 hours. The AP's were lug mounts, adapted to the mounts for the Corvette's. What is that trans? Looks like a very short tailshaft.
Oil pan is just about right height. If you put a belly pan in there (part of the aero package to manage air/air out), it will also take most all the damage going agricultural (short of a pointy rock). Besides, the
oil pan will push the junk away from the bell housing. I ran a windshield very similar to yours. At final trim, it put the air stream about an inch above my faceshield and the helmet was very solid.
Really like what your doing, I'm sure you'll kick that Lotus's butt.
