Pictures details and reasons for components selection.
Well the cam selection is critical.I wanted a cam with a good power band, but didnt want to sacrafice driveability ie: power brakes. This cam allows you to pull 10kph of vacuum at idle but can still get up there in the RPMs to make good power.I am running a 2000 stall converter so this should work out nice. I now am running the keisler 5 speed
You'll notice the larger gap in between the top and second ring this is a pressure relief pocket to ensure your rings stay where supposed to. The alloy Keith Black uses does not expand as much so you can run a tighter tolerance. The alloy reflects the heat back into the chamber so with my close chamber heads i should have an ideal quench and combustion. Also the ring spacing adds to the stability of the piston in the bore. It's supposed to eliminate cold knock.
Now for the most important part. I feel. I wanted really good flowing head, and roughly a 62cc chamber. The Edelbrock 64cc heads fit the bill with a 210cc intake runner I wont lose any throttle response and they come with the valve pocket already worked. The angle spark plug location is to gain a better flame front in the chamber(I believe). the closed chambers allow for a very good quench compared to the stock head on the right.I had these milled down .012" to make up for the 5cc valve pockets in the Keith Black pistons
