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.
Your better off using a Little-M block as they will clear a 3.875 stroke with steel rods and go with a 3.875 X 4.185 bore to get your 427 SBC. And those blocks will go 4.200 if needed.
And they make custom pistons every day
We are WD on Dart blocks all machined if interested give me a call.
