Do the 4.1 stage 2 blocks need to be clearanced for a 3.625 stroker crank with a 6.350 rod like a stock block or do they have more clearance? Thanks
 
Iirc the stroke on 4.1 are the same as 3.8. only the bore is bigger.
If true clearance should still be problematic.
 
You always need to check for interference, but I don't recall much if any issues on Stage II blocks. It has been a while since I dropped a crank in a virgin block though.
 
If you're running a 3.625" stroke you'll need to clearance the bottom of the cylinders and the top side of the big end of the rods just like you would in a stock block.

Thanks for correcting me Neal.:oops: I remembered the rods, but it has been too long since working with a virgin block. I do have an on-center virgin block left though.;)
