SBC 427 Stroker Build (w/ Dart SHP 400 Block)
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. |
You might PM hink he really up on the Dart blocks. I think he can probably answer all you questions. :)

As far as the cam goes. Unless you use a block with a raised cam, you will have to use a small base circle cam with a 4 inch stroke crank.

X2, i built a 434" Lil "M" and had Bullit grind my cam to .870 base circle to clear the lunati promod rods, typically most base circles are .950 and will not clear a 4" stroke unless it's a raised cam blk.

We just finished a 427 using a SHP block, Comp Cams .685 lift roller, used Eagle CRS6000BST2000 Rods, had tons of room, cam was .940 base circle.
Any small base will clear. |

Yes, Compstar rods will clear up to .660 lift using .900 base roller cam, use .875 base you will be fine for higher lift.
