377 or 416 CI
I am in the position to upgrade the engine in my ZL1. I was originally aiming to do a 416, but recently have been told by multiple people that a 377 would be better. So I'm trying to figure out the difference between the two. Pros and cons. Mods are full bolt ons, ported heads, cam, whipple and fuel/meth and is mostly a drag car.

If your gonna rebuild the motor, 416 would be my choice.

No replacement for displacement.

Unless you're willing to throw on a bigger blower I'd stick with the 377

I was in the same position. I went 377 for high rev power.

Big bore short stroke and high rpm is what I would do...so 377 gets my vote.

All depends what setup you are after, I'd vote 377ci underboost vs the 416ci.

Personally am a fan of the stock stroke on these motors. I would do a 377 as well.

for me, I have a centri and small blower cam, I'd go 416, if I had a twin turbo and a high RPM cam, I'd do with the 377, if I had a PD setup dunno, probably a 377, NA it WOULD be a 416 no doubt in my mind on the last one.
