which is more streetable-comp cam?

Honestly, I would have said it was too much for what you had, and the only reason it ran what it did was the rpms. Because really that's all you do by raising or lowering static compression. You move the power peak rpm points making an engine fit what you're doing better. With the auto, lower gears, and less weight, plus the ability of a good convertor, I'd say advance the cam 4-6° and run it again. You're only looking at about .520 lift and 265 @ .050 is big, but not massively big. By advancing it you'll bring the peak torque down to where a decent race convertor can help with the loss of low end. I'd also shave the heads as much as you're comfortable and intake flange to match, and run a steel shim gasket. If you can provide the lobe number (not sizes, Comp's lobe part number) and the cam card info (for the intake closing event, ICL, and LSA) then we can play more with ideas...
