Do I really need a stroker?

I'm personally not that into strokers because A) I like engines with an "interesting" power band, not just mad torque everywhere and B) I'd rather put money towards my 5.7L Hemi swap which at the end of the day has more potential than the LA/Magnum could ever dream of.

IF I built a stroker SBM it would have big-port race heads like the Eddy Victors or some kind of W2/5/7/9 variant.

Maybe you should find another FABO member who has a 408 stroker-powered A-body and go for a ride? IMO only way to know for sure if you really want it...
