I noticed above normal “metal” trash during filter inspections and decided to look at internals. Found lifters going away and several lobes in bad shape.
After talking to cam manufacture (independent) and Trend I believe camshaft was not heat treated correctly. But it bothers me not nothing the reason for failure.
Both parties naturally denied being at fault, but lean towards improper heat treatment on cam. Still trying to learn.

Again, I appreciate your info.

Anybody notice any performance increase running solid lifter vs short travel hyd lifter??
Do the big cam co’s still offer optional camshaft treatments/coatings on cast cams and is it worthwhile??

Thanks

RJ,

It is not the first time the cam company you are using has experienced issues with the heat treatment of their camshafts. Heard the same issues from others. Also, as Glenn stated, the break in spring pressure has to be lower than the spring pressure you use for racing. I would pay the additional cost and use a steel core in lieu of a cast core. Yes, there is a difference in power between the solid lifters and the limited travel lifters and it shows in the Spintron.

We saw absolutely NO improvement on changing to solids
from low travel Hyd. Lifters in my Stockers on the Track.

I still use Smith/Schubeck time bombs in my stockers.
MY son runs the Trend solids in his Demon 340 Stocker.
I am looking for more to buy.

On my Stocker I run 200/400 for spring pressure and have used the Trend tool steel lifters without breaking in with old oem springs and had no issue before.
Now I had a bad experience and don’t need another lesson ...
I ordered set of lifters from PPP today to use on a cast cam so I will install some lite springs and change to my beehives after run in stand session.
I never had an issue with schubecks/smith style lifters, but still hear horror stories of bad experiences.

Appreciate all the info

Thanks

RJ i think that the bigger lifter helps the Smiths live i have talk with a couple of ford guys say they never had a problem.
