Wiw early hemi

You need to make SURE it has the good oval exhaust port heads too. Then for sure, if it runs good, has no water in the oil and doesn't smoke a lot, it's around 1500 for sure. They aren't a gold mine like the 392, but they are still a Hemi. More than 1 HP per cubic inch is easily reachable with the right mods.
As I recall, you built or are building an early hemi...on the cheap no less...!
I admit I kinda drool over the early hemis!
