It all seems pretty street oriented to me from the info you have provided.

First the cam,any ID #'s would likely be on the rear of the cam.

From the specs you quote it sounds like a crane or possibly a crower cam.

Cranes #283942(h-272-2/hmv-272-2)cam is real close to your specs.

Crower has a couple similar grinds too(#60918/288H,and #60241/276HDP).

These would indeed be considered a "street" cam.

My money would be on the crane,and all are ground with a 112lsa.

As far as the rest it sounds like a more or less stock low compression 400 from the codes you give.

The '71 #96 heads would have originally been appx. 96-98ccs.to be certain of chamber size would require cc'ing them.And those heads on an otherwise unmodified 400 with flattop pistons would give around 8.0:1 compression ratio.

Again this sounds like a "street" type build to me.

There are 400 "domed" pistons from TRW/federal-mogul #2279,if these were used with the #96 heads it would have about 9.25:1-10.0:1 depending on if the heads were milled any.

The torker is the one item that seems "out of place" here,though that could have more to do with what was available as opposed to being specifically chosen for the combo.
