Stop in for a cup of coffee

So I have some vacation time coming up.

So my co workers asked "you going to Vegas and party out your vacation, maybe come back married"

I replied " not a chance, I have cars to build"

So my vacation is being planned around a 70 dodge D100. Original slant six truck, I pulled the original slant out and it's toast.

So the next natural thought is to replace it with another slant that runs.

Ok, so I have another slant in stock and it does run so I just need to swap the motor mounts and oil pan and drop it in.

Then i had a thought. I have a 66 fury with a poly 318. It does run. I really don't see myself spending big money to make a performance engine out of the old dinosaur but since it runs, there is no way I am throwing it away. I am not really wanting to leave it in the fury because it doesn't fit the goals of the fury.

So tonight I had a thought hit me. I have been hearing over and over that poly 318s make good truck motors. (You can probably see where this is going)

70 dodge D100 + 318 poly:

Good idea. Or Bad idea????

One pro is it would be a power upgrade, although I don't need the truck to be a racer

One con is a 70 D100 was never available with a poly, by 70 they used an LA

One more pro is it would be a good home for the dinosaur poly.

One more con is I don't know much about the poly so what do you guys think.

The poly is a good engine. Tough as nails block, good oiling and cooling. The biggest thing is it weighs a buttload for its displacement, almost as much as a B series big block and depending on accessories, can near a stock RB.

The other issue is parts are expensive. Intakes are 3-5 times that of an LA or BB. Cam choices are pretty much custom grinds.

That said, with a stock cam and a stock 4 barrel and a good tune, they can hit 275-300 hp easily. Limited mostly by the crappy flowing manifolds.

There’s been people pick up 75 hp on a just a header swap on a dyno. Course header choices are limited and pricey. All depends on what you want to do.
