Should I go Big block or Small block?

I drove a 273 with 11 to 1 pistons, 340 crank and solid lifters and LOVED it! Still have it tucked away, but now that I have had a 340 with the X heads for the last two years, I can honestly say if you have one go for it! Yes a 360 is good and cheaper to build, but the 340 has been a blast!
