Greg's Notes:
After looking at these tables, (and more dyno runs we did on 6/8/05) I'm thinking that we should limit our boost to 12-15 pounds, richen up the carb (maybe toss the Quadrajet and go with a Holley, about 600 cfm, and explore the distributor curve. We are using a stock Chrysler distributor internals which certainly won't be helping with retard at boost. The engine may then rev to 5200 rpm without detonation.
Assuming a working rpm of 4800, we now need to figure the optimal rear-end ratio. We have a 3.00:1 and a 2.80:1 rear ends.
The oil pressure didn't go up much, but I think we are getting a large volume thru. I will adjust the preload on the relief valve, add some type of oil cooler, and explore the oil line situation going to the turbo. This is entirely open, and Corky Bell suggests that some type of restrictor go in to bring the pressure down in the turbo. This would bring pressure up in the rest of the engine. The oil pressure readings are similar to those from last year, and when the engine was inspected, there were no signs of inadequate lubrication. It will also be time to shift to a multiviscosity synthetic oil.
