I'm thinking about swapping cams in the Imperial.
Quickie rundown:

5300 lbs dry
255/70-15 tires (29" tall)
3.23 gears
440 engine
Edelbrock heads
iron manifolds (maybe switch to HP pieces)
wonderful 1972 low compression (8:1 if I'm lucky)
a518 transmission (.69 OD)
port fuel injection

The intent is to build a highway cruiser.

In stock form, the engine is sufficient at best. The car will cruise nicely but it's burdened a bit by the 1960s cam laziness.

I will not pull the engine so I'm stuck with the low compression.

So, what kind of cam does this thing need?

I was eyeing the Hughes HEH1019BL but doubt I have the cylinder pressure to make it work well.
