Some small block strokers are very close to being squared, some consider a very good thing for a dual purpose car.

Im working on a 3.97x4.00 small block now,my 410 at 4.04x4.00. ect..

I dont know how that compares to the BB strokers but with some of the results of even the source kits, which seem priced decent are doing good things and crazy tq numbers.

Sorry to go off track a bit, most my BB cars were long long ago. But id do one if I could pop for a proper bb tranny.
