I think cam specs will play a big role in driveability, especially with a lighter flywheel.
I was initially disappointed with the driveability of my 383 stroker Cleveland engine with lightweight crank and aluminum flywheel and thought about going back to the stock flywheel. But after discussing my cam specs with several folks more knowledgable than me, I now believe it's largely a product of my cam's LSA.
Added my cam specs:
Duration @ .050: 226 int / 334 exh
Lift @ valve: .576" int / .586" exh
LSA: 110
My driveability disappointment/concerns were largely around low speed idling through a parking lot or down the street where it seemed "herky-jerky" and wanted to chug. Keeping it in a lower gear and keeping the revs up a bit more seems to overcome the issue, or I've just become accustomed with how I need to drive my car now after 3500 miles on the new engine.
I still plan to dyno tune it in the next month to improve response when slowly rolling into the throttle, especially below 3,000 rpm, while crusing down the road.
