I have a few questions about a SBC 427 stroker build, using a Dart SHP 400 block w/ a 4.0” stroke crank and H-Beam rods w/ cap bolts (possibly CompStar rods).

1. Will the Dart SHP block require additional clearancing for the 4.0” stroke and H-Beam rods? Also, which are the best rods for the clearance issues?

2. If I used a 3.875” stroke crank, does that crank require clearancing the block?

3. Will I need to use a small base-circle cam with a 4.0” stroke? I was hoping to reuse my current Comp solid-roller cam in this engine?

4. If I use a Dart Little M block (in place of the SHP), will Little M block require clearancing?

Thanks in advance for your answers.
