Hi , I searched but nothing shows about what i'm looking for ......

Can install 4.100 or 4.125 stroke on 5.7 with 3.905 bore ? , If not so what's the largest stroke can go with this setup ? , I know the 4.000 stroke will fit directly but need something bigger , Wanna build this combo for a customer and he don't have enough budget to buy another cyilnder block .

The motor will be around 11:5-12CR , It's for N/A and small shot for nitrous

Thanks in advance

I believe the 4.000 stroke crank making it a 383 would be enough.. Possibly see another 10-20hp from the extra cubes?

Couple of people done stroker with 4.250" very well in LS1 cylinder block, but it require some trimming modification of the block...

4.100 setups seem to hold well with correct piston rod combos.
