When I enter my "old" info, the results appear to be reasonable. But, when I enter my "new" info, the results seem, as mentioned above, "optimistic".
I'm going from a fairly standard 400(+.030), to pocket ported/port matched Kaufmann 60cc aluminum heads(10.44:1CR)(my pistons have a 13cc dish and are .028 below deck hieght),2.11/1.66, 1-5/8" Hookers, Edelbrock 750CFM carb and Performer intake, 220/231 w/110 degree lobe sep. Lunati cam, 1.65 roller tips, and ...thats about it.
I'd be interested to see what someone else comes up with re their Dyno software.
I'm a hobbyist. Not a professional. Don't be hatin'!
