My poly was beginning to get a bit shabby from misc disasters so I did a bit of work on it to improve the looks. These pictures are my components mounted on a scrap poly just so I can see what it'll look like with out the car wrapped around it :-)
I am now putting it together with a new 284deg cam and major massaged heads. I am going with old school metal head gaskets to increase the compression ratio. My new CR will be 9.66/1. My original CR was only 8.64/1 due to the fact that I gave an incorrect value to Ross pistons when they made them for me. I specked .020" for the head gasket because that's what it said in the service manual. The composite I used where actually .040" plus the heads were 78 cc's and I thought they were more like 74cc. Anyway it ran pretty well with the old 8.64CR and I'm anxious to see how the 9.66CR runs!!! I did run it for a short time with the new heads and a composite gasket so I had 9.1CR at that time. It ran excellent and turned an extra 1000rpm's over my previous heads and smaller 264deg cam. I'll have it ready within a month and when our local 1/8th mile opens I'll be there!
