And this has driven me nuts my entire life. Why run good enough? If your sweep is wider than .050 the geometry is off, wrong, incorrect. Why not fix it?
It used to be expensive. You used to mill the stands off, buy the offset blocks and stands and correct the geometry that way.
With Mike's kit, it's almost a simple bolt on. You may have to grind the holes in the shafts offset. But that's about it.
I've seen more junk come through the shop with "good enough" geometry that beats the seats and guides out. I've seen broken valve locks and retainers so ate up from harmonics that I was surprised it didn't fail.
I've seen valve springs get blamed for failing, when the geometry was off and the spring was taking the brunt of the load.
I've seen an engine pick up over 500 RPM of USEABLE HP just by fixing the geometry. And the curve of the graph was smoother.
I can sit here and continue to preach on this, but the guys who've been doing it wrong and getting away with it, who won't admit they are getting lucky will continue to foul the Chrylser world with anecdotal nonsense about how so many guys do it.
I know for a fact, that there wasn't a Super Stock guy in the country who wants fixing their geometry back in the 70's and 70's. How do you thin I learned it?
Fix your geometry. For the simplicity and cost effectiveness of it, there is NO REASON to not do it. Ever.
Unless you are running stock rockers, stock lift, stock installed height, your geometry needs to be corrected.
