Hello, engineheads. Or peterolheads; whatever you prefer.
It's like this: my 347 have comp 838-16 mech. roller lifters. Purchased in 2005. worked perfectly, but have been in "hard" use only 2- 3 seasons. I'm a bit worried about rollers failing....
Now; in the 2010 Comp catalogue, this part number is listed as a "Endure-x" lifter with EDM
oil injection technology to the rollers.
Question is: Does my 2005 lifters also have the EDM injection?
Question 2: How often should I inspect the rollers (visually/ testing the rollers) and how often should the lifters been shipped to Comp for inspection/ repair?
Question 3: Are there any cylinder heads for SBF that have the possibility to remove the lifters without removing the heads?
These heads should also have 60cc combustion chambers and be capeable to do 600 Hp, have the inlet ports at standard location, wide exhaust bolt pattern and be reasonably priced....
The reason for this question is that I'm (re-) building a long rod 306 and might use the heads current atop of my 347 which might be retired from the street (-legal) car and go into some kind of race-build.
