**600hp sbm block limit? Or is it bs!!**

W heads are all based on the W head with minor fixes to a specific issue they had in a certain area, like the reason the rocker gear was changed was that nascar sustained use had issues with the 2,5,7 gear, which was unchanged from the orginal W so a late 7 was made that eventually became the w-8, the w-9 is the lighter answer to the heavier w-8...
The 7 had a elongated 5 intake runner that found its way to the 8 also.
There are some strange one off versions of W's though, like the 8 that kicked off the P heads with it's 9 degree and the top secret unmarked W2 that looks like a 18 head that supposedly something like 50 sets were made.

Another issue as i have always seen a major problem in the mopar camp was it's split into 2...
And of the 2 the second group which is larger is also splintered into that stingy area you described where they can't get out of 1950, no matter what you show, do, explain.... they're in the slow 1950 state of mind or simply won't make it better.

The other issue i always see is expense, from my own experience and dealing with the performance mopar world from my own shop our group cuts almost EVERY corner.
I had done work on a few well known cars seen on tv and they could have been so much better, but they listened to who i have no idea who they were listening to but they clearly had no clue and did really poor in the performance of things.

Yes 5.7 HEMI has the same tag as MARINE, you want a HEMI translates into someone paying more .
There is a intake manifold for the new hemi's, no need to keep the f.i. , why some don't drop a new hemi than that STUPID idea that a mag version sb is better than the LA.
Me i'd drop a V-10 in over either, way more power potential and way more street friendly.
I still don't know how in the world a mag motor designed so that mopar no longer needed 2 different variations of heads for 2 different bottom ends and the mag head being better is beyond me, those heads are such a bottle kneck but everyone is doing it....

Just like the 451, how the hell did it turn into putting the entire recip of the 440 into the 400, when what made the 451 make the better power was the use of the 440's crank only and keeping the 400 rod on the only thing used from the 440 which was the crank which changed the RR, which changed it's breathing ability and increased power across the entire rpm band....
Now everyone builds lighter 440's....wth
Our camp is very often it's own worst enemy.

We still have the same dropping the ball manufacture that STILL doesn't understand "YOU WILL not sell that well on monday if WE can't make it better tuesday" Many people don't want to chance it knowing the headace for aftermarket support, but then the aftermarket sucks too, c'mon edel making heads off the mag design... wtf are they high, why would they do something so stupid why not do it off the W design
Like for example the trucks, everyone wanting a truck wants it to work and do work easy.... so gm does the v-8 dura diesel, ford the same with the v-8 powerstroke, they add an additional 100ft lbs, and dodge and cummins drop the ball and simply meet the 100, meanwhile the VERY SAME 6.7 being used somewhere else is making more than the 800ft lb and more than 430hp, so why not REALLY hammer the competition than simply meet it...
