HP is what makes you go fast, you can always use gear multiplication to make TQ if you have HP.

Now that is out of the way I like SB strokers the best. Lots of HP, good blocks (5.9 magnum) available for cheap, I can buy useable cores for $100, and they are already set up for a roller cam. 440s typically start at $500 and up depedngin on what numbers are stamped in it. Throw in another $800 to get the roller cam/lifters.

If I build a lot of 600HP+ engine I would consider the BB more but I will take a SB/904 combo and #200 weight break on a street car for me or most of my customers
