440 Crank in a 383

The 383 block is a much stronger block than a thin cylinder walled 400 block....

By the time you pay to turn the counterweights down and then have the mains turned down you can buy a 4340 stroker crank for not much more.


383 block stronger...is that true? What makes them stronger?

I agree that the finished crank cost is probably comparable, but if you are only buying pistons and having the crank turned them the 436/541 is probably still going to be a bit less expensive.
