You are 100% ignorant if you think the Chrysler rocker shaft system is anything but MARGINAL at best.
Once again, it’s evident you haven’t a CLUE what it takes to make power at a respectable RPM. Five 3/8 bolts will NOT hold the rocker shafts anywhere near rigid you need to stick to golf.
And then the passenger car heads have five 5/16 bolts!!! Trying to run a roller cam and any RPM over maybe, MAYBE 6k is DEATH to the valve train.
Lets talk about the much vaunted Hemi and it’s shitty rocker hold down system. And it’s stupid long exhaust rocker.
There are 5 (FIVE!!!) 7/16 bolts (or studs depending on how its put together) to hold down TWO opposed shafts. How in the **** do you think that works?
The answer is it barely does. BARELY. The shafts move all over the place.
Maybe rather than posting here you need to go find some Spintron video of different rocker systems and see how bad this 5 bolt Chrysler **** is.
Then go look at something like MBE or Steve Morris’s SMX engines mount their rockers.
Continue to think you have a clue about what a race engine is and does.
You wankers only play with garbage so you can’t see the difference.
BTW, look at the Alan Johnson 481X engine and see how he built the rocker gear for that.
I finagled my way into a full set of engineering drawings for the W5 head. Took me a year of digging before I found someone who could hook me up.
I spent TWO YEARS working with the drawings to unfuck that head. The W7 was discontinued and the W8-9 stuff required too many parts that didn’t interchange with W2-5 stuff and I know, for a FACT that if a guy can’t use most of the stuff he has he won’t even sniff something new.
When I finally had some roughed in dimensions and ideas I got on the phone. The cost just to get the first set of core boxes was astronomical.
Also finding a foundry to run the castings was about impossible.
That head would have easily gone 420 CFM with a reasonable port window. AND, I addressed the shitty rocker mounting issue. It would have had eight 1/2 inch studs plus eight 7/16 perimeter studs.
Of course, getting all that done was a task but in the end reality sets in. Chrysler guys will never upgrade to something like because too many think like you do.
You retard the industry.
Piss off wanker.
