Trick Flow 190 Heads, hydraulic roller cam, and pushrod angle Question.
Fair enough....but a solid flat tappet requires little maintenance. I might venture to say if you ain't willing to adjust some rockers, maybe you oughta stick to the Camry. Lol
Again, one man's opinion. Some guys want to drive their car and not have to work on it. Some guys aren't as skilled at doing valve adjustments as others. Some guys don't want to spill oil all over their detailed engine compartment. Add to that the noticeable decline in flat tappet lifter quality of late, and the requirement for more expensive oils or additives, and a hydraulic roller has some appeal. Personally, the older I get, the more I hate hanging over a fender adjusting lash. And again, most street engines will spend 95% of their time between 2000 and 3500 rpm.
I get what your saying. I tell people if they are going to run a roller rocker they need to correct the rocker geometry. Otherwise, leave it stock if the factory engineering is "good enough". But, many don't do it. The difference is that a hyraulic roller cam will run for hundreds of thousands of miles, but a motor with bad rocker geometry probably won't. Something will fail prematurely.
I run everything, but from a liability standpoint, and not knowing what the customer is going to do with/to their motor, I use rollers whenever I can. But, solid rollers just aren't practical for a car that gets driven a lot, but doesn't get maintenanced a lot. Just another man's opinion.
