Max lift/stock slugs

True.

Here is my deal. I have a 2000 5.9 Dodge Durango engine ready to come out and be installed into a '79 Dodge Magnum without the computer. So far I have purchased a RPM, Hooker Super Comp headers that will go into a 2-1/2 exhaust, a B&M flex plate for the neutral balanced Summit verter, a low stall unit.

The car also has a 9-1/4, 3.55 gears, tires are slated to be 245/60/15's.
I also need a (in-line?) quite fuel pump for this total street driver.

While I would call this "A not so balanced set up", it is only to get the car up and running now and I'll address the short comings later, which would be cam and heads.
So I'm now looking at cams for later on.
so, what was the original engine?
