I have R-M built 583” BBC in one car and a 588” R-B built Mopar motor in other. One makes 150 hp more than the other and was $8000.00 cheaper. The Mopar is a wedge head, both are aluminum blocks, the Mopar is an Indy block. Bet you can’t guess which one is which. Jim.
Because not only do we have a block porcurement problem, unless you opt for the best of the best HEMI heads for a boosted application, they are playing with spaceships and we're stuck with chariots in the cylinder head department.
The cost difference is understandable and makes sense economically for a variety of reasons, so that part of the equation doesn't bother me nearly as much as R&D/availablity nightmare.
