The new popular Hotrodding has a nice writeup on a stroker 6.0 LS using a 4.10 stroke Manley crank, Eagle 6.125 rods and a Manley pistons.
Built by Racing Engine Design for the Engine Masters and made a peak of 643HP and 600TQ.
The bulder states "you don't have to do a thing to make the crank fit. There is no clearancing or anything needed"
I always heard that 4.0" cranks need the block clearanced to avoid the rods hitting. Is the story right?
Can a 4.10 stroke crank drop right in a 6.0 block and using a .060 overbore get 425 inches?
Anyone on here know for sure?
Thanks

It's done all the time. Typically with a 2.10" or a 2.00" pin there is some clearancing needed, but it's very, very little. The trick is in the piston's design. Do a search as this topic has been thoroughly discussed.

I think you have to clearance an LS1 block for a 4" stroke crank, but not the iron blocks. That's probably what you have read.

4.0 stroke is the max I would run personally.
