Default question about 4.1 stroker crank

i found an eagle stroker crank for pretty cheap that would take the stroke up to 4.1 from 3.62. also found 6.125 in H beam rods. i think it would yield somewhere around 395 cubes. could i do this with stock pistons and 6.0L or LQ9 heads? i spun a main bearing recently and figured i may need a new crank, so why go with stock displacement if i can get this setup cheap? and when i order new main/rod bearings could i just order stock-style pieces? any help is greatly appreciated. thanks.

No stock pistons, the pin placement is different.

Will a 4.1 crank fit in a F body pan?

In the past, there has been oil consumption problems with 4.1" cranks. There is not enough deck height to place the rings correctly in the pistons using 6.125" rods.

I just had a 418 built using a 4.1 eagle crank. The engine shop said i should not have any oil comsumption issues, at least none more than a 4.0 crank motor.

Oil consumption is not an issue when the builder uses the correct pistons/rings!

Stock pistons, as mentioned above, will not work due to pin location!
