Isn’t a big gap because there is very little market for it.
For one thing, 700 horse( real track horsepower) will require an aftermarket block, Other than +- 3300 plus machining for a Ritter, you are looking at a 3-4k R type block IF you find someone selling.
The above hurdle alone makes anything to follow on the build extremely finite.
Got the “ new money” crowd driving around already in 700+ horse modern hemi cars( or putting them in older stuff more increasingly every day)
then you have the ultra high end guys skipping right over this stuff and going W8/W9 Much better 48 degree stuff.
Virtually nobody got their toes wet on the Victor heads because they were 3500 bucks for starters, and you still have the block dilemma and no “ kit“type pistons available for a 15 degree head. Hardly anybody brings them up, or wasn’t even aware Eddie didn’t have any until Jack Barna did that 376 cube build that has been seen now by quite a few people. It’s just a dark black hole with no blocks that are suitable
The fact is, like it or not, the 59 degree Chrysler small block stuff is by and large a dying breed, made up of old timers like me and Pittsburgh racer and others that still are dinosaur lovers.
And there is plenty of stuff around that will make 600+ and a stock block will live under that is readily available.
