Has anyone built a stoker motor using a B20A crank?
Is it identical to a LS crank other than the stroke? with custom length rods couldn't you obtain a nice stroker kit for dirt cheap compared to crowers' crank?

you can always add deck height + move wrist pin then get custom rod ... SAAB has a timing belt to fit, use prelude distributor p/u driveshaft and custom adj cam gears that have deep slots.
you can go thru that if you want, but i think you said something like "cheap" so jsut stick to 89mm crnak i guess.

Let me rephrase, relatively inexpensive vs. Crower stroker crank.
As for rod ratios, I am not concerned as this can not be compared with a stock motor. As many threads before have discussed, some people are much to concerned with r/s ratios. If my powerband is not going to be from 7500+ rpm, well than I will move the powerband lower by adjusting cam timing etc. When you are dealing with a completely built motor with balanced crank, lightweight forged rods, lightweight forged pistons, reinforced mains by a girdle etc, you are no longer dealing with a stock B20A.
