From using a smaller cam but a 10 SCR and 8 DCR on a 340 with a 2200 RPM stall, it is not the least bit soft from a standing start. I don't think 2500 is too small for your larger cubes since you have kept the SCR and DCR up. Easy to change the TC later if you do not like.
Ok I had one old mopar guy that suggested this cam that with the compression ratio I have the 2500 should be sufficient now with that being said if I do go stroker then a 2500 stall should work really well
