Bottom end goes together:
All the main bearings are clearanced within .0001 of each other, for very even oil distribution. The goal is not so much max HP but a high HP build that will be very reliable.
Brodix RR-O heads are purchased. Out of the box they have a horrible run-out on the valve seats (max of .009; when we want to see under .002 at least; ideal is under .0005). The guides are honed, valves are checked (they are really good less than .0005 run out on the valve face). Machining the valve seats is done and a run-out of under .0005 is attained. The heads are surfaced (the surface wasn't perfectly flat, plus wanted to raise the compression just a tad).
The intake and exhaust ports are ported and polished.
The chambers are cleaned up and CC matched within 0.1 CC of each other. The heads are vacuum checked (20in of Vacuum they seal nice and tight). Should have a real nice and even compression ratio across all cylinders of 9.8:1:
Cam goes in:
It is a Comp Cams "Thumpr" roller cam 227/241 @.050 547/530 lift 107deg lobe separation. I went with the Thumpr as from my understanding a common weakness of a big block is it lack of exhaust breathing. My hope is that with the 107 deg lob separation and the increased exhaust duration that this will help correct some it.
