By all means, call me and I will explain everything to your satisfaction. The geometry kits are guaranteed or you can return it for a full refund. There are plenty of people with real world experience, but they aren't talking for some reason. They haven't returned their kits either, so I have to assume the are happy with them.Just curious if anyone has used their geometry correcting rocker stands they make for shaft mounted rockers. I'm looking for real world experience with these before I decide to purchase them. Thanks.
Mike - I've used support blocks before to adjust the shaft centerline and correct geometry on specific engines. This is the first time I'm seeing/hearing about your stuff. I went to the website and didn't see much besides general theory. Do you have a catalog or pricing sheet you could add?
I set up the website to be more informative than sales related, although that is going to change here shortly. I make these kits customized to each individual engine, so a simple online order is not possible to make it right. I can tell you this, the kits are $180 and include offset billet shaft spacers, offset billet hold downs, hardware, instructions, and in the US, free shipping. Figure that with a 100% satisfaction guarantee, and it's hard to go wrong.
I submitted my next tech article to my web designer, so keep an eye out for that to be online in the next few business days. There is a lot of misconceptions about valvetrain geometry in the Mopar world. Basically, you can forget most of what you've heard for the past fifty years or so.

Not knowing better, I'm assuming the pushrods need to be swapped too? Will they need to be measured and made custom to fit whatever the combo is? Or is there some fixed number 'longer than current' (example: add .180" to your current length), or do they simply get re-used? All the logic and engineering makes sense, and it seems a prudent upgrade for anyone with roller rockers or non-stock cams.
Yes, you will need longer pushrods, but a well built motor will almost always need a custom pushrod length anyway. It needs to be measured after the correction is made, and I always recommend running the longest pushrod possible.
That's what I'm talking about!:cheers:Mr Beachel,
IMHO, You need to post more often...
Waaaaaay Baaaacck in My build days, there was this 'Short Fuse' 340 that would wipe
valve guides after 8 runs...
We finally figured out... heavier/ longer pushrods & raising the rocker shaft (1/8 th inch)
Transferred rotational force in a more lineal line, ... weight is (sometimes) a good thing...
Sorry for the Rant Sir!!!
That's what I'm talking about!:cheers:
mopar shaft rockers are in the ballpark geometry wise most of the time with made in usa rockers.
change 1 thing + u MUST change the position of the shaft-not.

my 340 is running 11 seconds and street for 20 years with Manley 11/32 valves and .550" and lightly cut heads and block and old harland sharp rockers on stock pedestals, and she go to 7100 all day with no problems, I guess I am lucky my geometry is good!
I'll buy that, as soon as you can explain the difference between a made in USA rocker and an import rocker as it relates to geometry.mopar shaft rockers are in the ballpark geometry wise most of the time with made in usa rockers.
I'll give ya the "lucky" part. Sorry, gonna call out the good geometry though.my 340 is running 11 seconds and street for 20 years with Manley 11/32 valves and .550" and lightly cut heads and block and old harland sharp rockers on stock pedestals, and she go to 7100 all day with no problems, I guess I am lucky my geometry is good!
I hope not! I want it to be informative from a math (geometry is math, right?) perspective. It's not about opinion, because the mathematical principles are set in stone and proven for thousands of years. Of course there is always someone who is willing to argue that 2+2=5, just for the sake of arguing. That doesn't make it right, and those who are willing to think for themselves know that.:glasses7: This is looking to be one comment away from another "hellcat" post. Trolls be trolling......... :glasses7:
ETA on the next TECH article ??? :glasses7:
Get busy :cheers:
