I don't know if a 4" stroke crank will fit in a stock 350 block but if it doe's i'm thinking the block will be one scary looking piece. Seems to me you would have to grind a lot of material away to achive proper clearance.

From what I understand, a sbc 400 stock crank will fit with some machining on the mains. Don't know if this is true. Just thought I'd mention it. There are a few crank vendors that sell the 350 crank with a 4" stroke. Maybe the cranks are for Dart blocks. Don't know.

There are several people around here running 4" cranks in stock 350 blocks. i CAn aask but i believe they are pouring very little block filler in the bottom of the block, below the sand casting plugs and then grinding away.
