Rub,
Cams were a lot less aggressive back in the day. The valve spring pressures back then were basically the spring pressures that I'm using now, without the inners.
There's also a general disagreement as to why flat tappet cams fail these days....metallurgy, oils, lobe aggression, spring pressure, etc. I don't do a lot of these, but when I do, I have all my ducks in a row: make sure the lifters all rotate, run Brad Penn break-in oil, take inner springs out, and I usually run a Bullet cam since they have more taper in their lobes, which helps the lifters spin. I also run the Crower EDM lifters as well, as they have a direct oiling hole that keeps the lobe wet.
Cobraboy, I didn't have any issue until a few weeks ago when I updated by Photobucket app on my iPhone. I snap all my pictures with my phone then upload it directly through the app. The new version of the app just plain stinks. I'm looking for something different. |
