Originally posted by jaroot Just FYI... nearly every valve in factory automotive and heavy truck engines is manufactured by Eaton. Manley valves are Eatons, exactly the same valves as the Eaton private label, they just cost 3 times as much. Ferrea also uses some Eaton valves and put their name on em... It is true that Eaton friction welds heads on a lot of their stems... they also manufacture some valves from a solid piece of stock. either way i've seen em on the instron and they can withstand some pretty impressive tensile and side loading with a heckuva long fatique life... Most lifters, flat and roller are manufactured by Eaton also... even the aftermarket hi performance rollers marketed by comp, crane, isky, etc. I am an aquaintance of the gentleman that manages aftermarket sales accounts, etc... as well as a few folks with a lot of years of experience working in Eaton's valvetrain dynamics and durability lab... I have heard the same thing jaroot. This is a fact I am sure marketing people at manley would just as soon leave unsaid :) Now we just need the brand name of the low cost valves that are identical to manley inconnel and SS. Dave |
yea, that would be nice.
