I would think 350 drivable and dependable HP should not be a problem. The heads are going to make power through out the rpm range.

Mine was a stock cast piston .030" over engine with an Edelbrock Performer, mild port and match 302 heads and a Comp Cam XE 256 H camshaft In my D250. Lots of low end grunt and surprised me on the top end. The Air Gap might be too big for 318 heads looking at what your wanting for low end torque, don't overlook the cast iron 340/360 manifold, excellent design and cheap.
Ran a 3.55 gear with lock up auto O.D., then a 1 to 1 833 (always felt like it needed one more gear), then an overdrive 833 was the best. That thing hauled more than it should have and never gave us a problem, still got the engine.
I like the donor truck idea, get all that modern suspension in there.

THAT is the setup I would run. Good for more than 300 horse, trust me.

I like your thinking about your build, take it slow. One thing I've seen is too many guys rush in and build their engine first because it's fun then have it sit for too long while they build/prepare the vehicle. If you have a good builder who can turn this over quickly then I would wait until the vehicle is close to completion so the two can come together at the same time.
Here is why I've come to love the Chrysler 318 even when some who really don't know the V8 engine say it's just a reliable slug. All the big three made approximately 4" bore, 3 - 3 1/2" stroke engines that had forged pistons, big heads and cams added and became Z28's and Bosses and T/A's, then take the same basic platform, detune it and put in your Mom's sedan. The nice thing about a Chrysler V8 is the large crank to camshaft center line distance and near perfect connecting rod/stroke ratio, just wish they had changed the lifter angle from the poly to straight line.
What I'm saying is take any of the big three V8's with modern technology and build it into anything you want.
The great thing about 318's is there are millions of them cheap, and a quick internet search can bring up dozens of proven builds that can be copied with expected results.
