Help with cam selection
I think Comp's recommendation is a little out there...especially with a stock head. With that said, I think the "lightly ported J heads" are going to be your bottle neck with this combo, and could potentially keep you from your goal of high to mid 11's on a street car....not saying it is impossible, just not the best choice for a stroker.
For what its worth, my 410 stroker is using a smaller off the shelf "street roller" from Comp, the XE286R (248/254 duration). This cam along with some ported Edelbrocks and a 750dp propels my Barracuda into the mid 10's....and I can (and do) drive it all over town.
My point to this is, I don't think you need a monster camshaft to achieve your goal, but I do think you should look into some different heads (JMO). A more street-able cam will be easier on the valve train parts, and less maintenance...and the larger cubes of your stroker will be able to breath with better flowing heads. Going fast is all about getting a good COMBINATION of parts that work well together, and tuning them for optimal performance.
