Tired engine - weighing options
So one of my cylinders has developed a bit of excessive leakdown with accompanying rougher running and I'm thinking about what kind of replacement engine to go with.
The caddy ls6 longblocks look like a great idea, but I'd like to drop in a set of ported heads and a cam I never got around to installing. I sure hate to crack open what is essentially an extremely reliable package in order to do that.
I'd really like to go with a 427, but this is a daily driver and I want to keep that great highway mileage.
Any suggestions? Go with an aftermarket shortblock and maybe an in between step like the 383?
Thanks.

Centrifugal superchargers, become more efficient as the impeller spins faster, which provides more power at higher RPM.
Supercharging not only produces a cooler air charge, but it also reduces Engine load.

Edit: But if it did end up being a valve issue, I'd lmao since the leakdown results decided me to postpone the h/c upgrade. Those parts have been sitting on the shelf for over a year.
