The same motor has gone 144mph to the 1/8th so far with more left with the same stroke and rod which puts it in the 1600 range. You can use the 6.0 rod and be fine with the larger chambers or use the shorter rod if you think you may want a more serious head down the road which may have small chambers. You only want to buy the crank once. If you buy it for a 6.0 rod now and want to go to a 5.7 later, the crank counterweights will have to be cut down.
Our local class was cut to a 88mm limit at one time. The leading turbo car was running 11-1 compression with the 88 on C-16 gas. I don't know that I'd go that high but definately in the 10-10.5 range so you don't have to pull out as much timing. I have run 30# of boost with 9.8-1 already with no issues.
