I'm curious to hear your stories and decision processes.
I am also interested in knowing how it worked out and if you would do it differently next time.

Well since no one else is chiming in, I guess I will.

The correct answer is… it depends lol. Your forced induction of choice and fueling will play a big role. If you have a P1X, 1.7 or 2300 blower, you’re crazy to specify a 427 engine since you won’t have the airflow to feed more cubic inches. Similar thought process with a PD blower…I’m not a fan of adding a stroked-only bottom end. You don’t need more low end torque as PDs are hard enough to hook up with down low already. And you have to be able to fuel this all…many are reluctant to spend the money it takes to fuel this platform correctly.

That’s just the tip of the iceberg, but hopefully gives you a few things to consider. If/when my 377 dies I’ll probably do a big bore stock stroke engine from LME or Katech and spin it a bit harder.
