Bill; first answer is I am using my last block which is still in good shape.
The old block is done for. The second plug is in the radius of the transfer
port where it ends above the bore. I am hoping the turbulence from the
squish will spread the burn through the chamber without causing detonation.
The proof will be in the time slips. Rich

Subject: Re: cooling
Hi Rich, very interesting idea.
What are you doing about the cracks in the block?
No doubt the fins on the billet head will have considerable cooling
value, especially if you can arrange a duct to blow air from the front
of the car at speed onto them.
I gather most of the serious fuel flathead dragster guys make their own
solid billet heads for strength and better head gasket holding and run
no cooling water at all.
Apparently the piston is supposed to come within about .040" of the head
for squish-turbulence on a flathead, and supposedly this is necessary to
avoid detonation. If you do this, how is the second plug over the bore
going to figure into the equation? If it lights the fire say 20 or 30
degrees BTC, what's going to happen when the piston comes up and squirts
it into the valve chamber?
Just a few (more or less uninformed) thoughts.
Cheers Bill
