Sammy have you just tried breaking the cam in like we used too? I how, but some time we need to step back and start over, tool steet lifters, coated and 200 + seat pressure.Even the Nascar guy s are having problems and they barley run 200 seat pressure. Or did something else happen.

Rule should be changed to make roller lifters optional.

How about a rule like.....max 150lbs seat pressure!

There ya go! And at the same time, it would make all of those 396/375 Comp motors more like Stocker motors again!

This is a very big issue!
Whole lot of racers experiencing wiped out cams and engines.
The mechanical limits on cams and lifters can take has been reached long ago.
Yet Engine builders find ways and processes to add more.

Maybe a loping engine like a Olds 455 would not benefits so much.
Engines exceed 6500rpm, more like 7000+ are losing it.

Like beating a dead horse! (Need to post that picture again)
Keep the current cam rule. Limit the Spring.
Such as a Spring Ratio based on size of the Largest Valve.
NTE...some stated Spring Seat pressure!

Too much Spring Pressure is like More Snow

Like Mike said is true!!! the cost and time is unreal we need to ban together and loby for roller lifters. the big problem is the oil it's not there any more with all this EPA crap the world has gone in the tank. when you talk to the Cam people they won't sell cam's to the public without being a roller because of the oil. and the spring Pressure is not the problem!!!!!!!!!! it's the oil.

How many of you guys AREN'T using some form or brand of racing oil? Which all have the proper additives and such for flat tappet use. The issue is that many are running roller spring pressure on flat tappetts. You want a roller, go to super stock and get the intake that goes with it!

Yeahhhhh, no the problem is the spring pressures and the lobe designs.
