crank question
how far can you safely turn an 8ba crank for a lightly modified street cruiser?

Re: crank question
.030
You are not far from me, it seems. If you need a crank let me know, I have plenty. |

Re: crank question
Bearings were available up to .050" years ago.
Don't think they are around any longer |

Re: crank question
I am amazed at the concern at .030,.040, yet not much concern when 1/8 is taken off to make a stroker----- its more important that the crank grinding wheel has the correct radius--- but it takes time and grinding wheel loss $$ to change radius

Re: crank question
If you seriously want power, check into SCAT srankshafts ... not as expensive as you might think and available to well over 4".

Thanks, Gary in N.Y. P.S. In our opinion the best rotator kits consist of an Eagle crank, Scat rods, and Ross pistons (moly rings). It's just about all we will handle in "strokers" for the most part! Some exceptions, but few really!

Re: crank question
It's quite common to offset grind rod journals on Merc cranks down to 1.999 and use full floating bearings.
