cam thoughts

17%?!! That's the "10 inch" convertor. They're just not that efficient when yo ureally spin them. You should be less than 1/3 of that at the stripe. that's wasted horsepower and lost MPH.
Looking closely at both those cams - you're really only looking at another 10° or so between .050 and .200. It's almost no change. I wouldn't expect a dramatic improvement in power. I also don't think it's going to move up the rpm range much at all. They are very, very with the exception of the shape of the middle of the lobe. I'd suggest you change the trans and go witha real convertor, then tune it and see what it might want. Better doing one change at a time and optimizing it, then make another change.
