I'm still scratching my head as to why I pulled out a perfectly good 341" (3.91" 318 factory roller block with an MP 3.55" 4340 stroke) to put in the 414, I'll bet this puppy made about 440hp (PLENTY!!) with a 236/240@.050 Hyd Roller and stock E-heads.

I agree, never take the bores out any more than they need to, keeping the meat in the bores of a stock block is worth more power than a couple extra "ego" cubes.
