GT40 Heads...again

shot of CC 1.5 oz = 44.3 cc's

so that would be about a 2 oz shot to fill the chambers if they are 59cc

The method I most observed was similar to 79's with the syringe, but a piece of plexigla$$ was/is placed over the top of the chamber with a needle-sized hole drilled in it. This takes care of "bubble" effect.

10-4 Doc. Many of the mfrs have listed as much as a 3-5cc range when listing the chamber size on a specific head, and then list one single number as either an avg or nominal fig.

Side Note: Personally, and this is just from several engines we have, I'm big on the higher comp in our engines with these favorable power to weigh ratios. I don't know that I'd want 10+:1 comp in a cruiser under a continuously heavy load, but in several we've a$$embled with 10:5 and greater (theoretical/advertised based on piston and head combo of Keith Black KB-116 domed pistons and D0OE-60cc 351 heads) the results seem to speak for themselves with no knock or detonation even with aggressive timing and torque and acceleration is incredible. Not having another explanation, I attribute it to a continuous flow of cool water and thus the ability to maintain optimum engine temp. Elect ign doesn't hurt either I guess in terms of not fouling plugs and other issues a$$ociated with high CR's in vintage autos, esp when driving slow or heating up. Also, many of us use premium fuel when it's available whether it's required or not. Might as well take avantage of it. In essence, I'm not saying go build a 11:1 ski boat engine, but if you're looking at new heads which just might raise your CR to the 10+:1 range, don't worry about it and enjoy the power, if that's what you're after.

We're pulling into Mr.Jbears neighborhood next Tuesday, the 26th, and hopefully towing down our old beater testbed '69 Mustang so that he and whoever can take a fun testimonial mid-50s mph ride. It's the next closest thing to Bill Burgess' nitrous rocket. SS-201 Bill, you out there? I'm also looking forward to planting my butt in jbear's trophy winner. I'm stoked. If you're in the neighborhood, hook up with us please.    

I'll be there.

Good to go. I'll be there between 5-6 depending on traffic .

That would be no problem if CQ can leave early- I won't be able to stay long, unfortunately.
