Project89, since you've stated that this will have a forged rotating assembly going into a bowtie block, I'll throw this out as just something to consider. In Scat's standard weight forged cranks for 350 mains, you can get a 3.8" stroke setup for either 5.7" or 6.0" rods. The extra .025" on the stroke radius would put the stack height at 9.025" with a 1.425" compression height piston, so the block wouldn't need to be decked to get a .000 piston deck height with 1.425" CH pistons. With the 4.155 bore, it would equal a 412" engine. But, since the money is being spent for a forged crank, why not go to a 3.875" stroker crank (for the same $$$), with a 4.155 bore would make a 420" small block. Even a very mild build with 420 cubes will make your HP goal. Here's the Scat listings from the new catalog showing their standard weight forged cranks for 350 mains 1 pc seal blocks:
