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

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

If brgs are available don't worry too much about the under-size! (I do keep .030" unders, rods and mains, on the shelf for the 8BA's)

Under no circumstances would I recommend a Flathead Scat crank, only due to the labor involved making it work. He would also have to change pistons and most likely the rods? Definitely the pistons not sure about rods??

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

Gary has nailed it once again with his great advice.
He has just just helped & supplied a good friend of mine from the pacific NW with a kit & he couldn't be happier with al the help Gary gave him the first class service & how it performs.
He also loves the KiWi-L100 camshaft.
Cheers
Tony
