Was that run started at that rpm of is that just a snap shot of the dyno info? Most 60/62's I have worked on come in much sooner than that. I have a car with a 74GTS that would go head to head with the spool on that sheet. IMO the 60/62's are a lot more fun on the street and if you are sticking with stock fuel/ stock block you should stay focused on area under the curve.
Yeah, that's where my tuner started the run. He said with the 4.10 gears the turbo wasn't able to spool as quick as it would with some smaller gears due to the engine revving so quick. A turbo thrives under load, and the engine wasn't really working that hard with the 4.10's out back. I have since swapped the 4.10's with some 3.55's, and it would still break loose at 45mph with the stock motor. The boost comes on much quicker now with the 3.55's. I'm anxious to see what it'll do now...
