So this friend of mine bought a 1977 E250 Custom Van with a 460 engine. Some initial exhaust manifold work resulted in getting the engine out which gives an opportunity to refresh and rebuild it mildly. Nothing too wild. I could use some advise/confirmation about the pistons.

Heads are rebuild and stock (maybe some porting), new timing chain and I was thinking a torque cam like the Xtreme Energy 212/218 from Comp cams. To raise the compression ratio I'm considering the Keith Black KB137 pistons to get it somewhere in the neighbourhood of 1 to 9,5. My question is, will this setup take regular pump gas or do I need a lower compression ratio for that?

I'm open to other suggestions for pistons too.

I live in the Netherlands, btw.

We run the H612cp pistons at 0 deck and clean up the heads to get 9 to 1 static c/r for regular fuel.
The KB206 would accomplish the same thing for more $$$

A great torque cam for this application is 207 / 219 voodoo custom grind.

You are running exhaust manifolds?

No just stock exhaust manifolds, I should also mention a HEI ignition will be put on the engine. The main goal here is torque and mpg, maybe at some point the rear end can be changed too, but first the engine.
