I think after he eats and rests some and rethinks his path about how he got to where he is, he'll hit on where he took a wrong turn. The temp guage thing was referred to before along with engine grounds

Got to go eat and see how the race is going

I ran into the thing with the temp gauge this morning and posted it as a separate post.
The engine build took a different turn about halfway through as I found an issue concerning my heads. they were assumed to be 76cc and were measured to be 64's. As far as the build goes.......

4.030 bore
3.48 stroke
5.7 rods
70cc chambers(cut for oversize valves and took extra material to achieve this target)
4.135 X .040 head gasket
.125" dome pistons that cc'd to -.3 cc's in the cylinder
0.025 piston deck height
57 abdc intake closing.

this gives me a SCR of 9.63 and DCR of 8.13
squish of .065 minimum clearances in chamber of 0.060 checked with clay.
I have done my homework on this one. It is a solid build.
