And to grow that combo significantly to need a forged crank (100-150 more HP), you’ll have new cam, new valve springs, new heads or lots of $$$ to race port what you have, possibly improved rockers, and most likely new pistons.
At that point do you just build another motor and save/sell/transfer the old stroker motor?
That is the point I’m at, when I pursue more power I will just build another short block. Forged crank and bush the lifter bores for roller. I have to run the same top end.
