Thanks guys! You’ve given me a lot to think about!
One of the options I’m considering was suggested by Dynoroom 2 years ago, and I failed to follow his suggestion, although it’s obvious now that I should of. He suggested using ordinary sewing thread, like your wife uses to put buttons on your shirt, and put a single loop (with the ends parallel to each other) around each water and oil port. Put them in place with some spray on Hylomar.
The other option I’m considering, although not as much as Dynoroom’s suggestion, is stacking two copper head gaskets, and In between, milling receiver grooves for a wire coincident with the path of the block O-rings. We could adjust the loading by way of the wire diameter.
We’re still working to get our aero better, but I’m very encouraged with our progress so far! Using Sumner’s worksheet,
http://purplesagetradingpost.com/sum...20A%20Lakester ,and my fastest run of 189 MPH, I would estimate between a .4 and .45.
So, my HP needs look something like this:
CD .4 .45 .5
RWHP for 189 MPH 482 535 587
RWHP for 201 MPH 571 635 698
This, of course, assumes my CD estimates are close!

Input Rolling Resistance ======> .024 <== (Note:
Input Car Weight =============> 5000
Input Frontal Area in Sq. Ft. ====> 24.00
Input Cd For Car Body Only====> 0.45
Input Velocity in MPH =========> 201
Body Drag Force = 1064
HP for Rolling Resistance = 37 HP
HP Needed for Car Body = 598 HP
HP For 4 Tires/wheels = HP
For this Speed = 201 MPH
Total RWHP Needed is = 635 HP
So, what's the point? The point is, 200 MPH becomes far more achievable when one looks at the HP needed! If we can lower our CD, to under a .4, it will only get better and better!
