Ditto on Comp Cams. I would say 80% of the cams I use are from Comp and in nearly 30 of building engines I've never had one go flat. As far as them not making power, that has more to do with the person picking the cam and their ability to match it to the rest of their combination as opposed to the brand. They have some great custom lobe profiles if you know what you're looking for.

split thread

FYI for those interested I split this thread moving the sections about adjusting the kick down cable into the Transmission section.

The title of the thread is Kickdown cable adjustment.

I avoid cams with super fast ramps for that reason.

xtreme or voodoo cam have very fast ramps and are easily wiped out.

Softer break in springs, oil break in additive, and extra oil in the crankcase are a must with cam break ins. Plus you need to run an oil additive at EVERY oil change. (www.zddplus.com).

A heavy truck with stock converter, then I would use an old school compcam 260H or 252H and 9 to 9.5:1 cr with those vortec heads. And use stock springs for the break in.

after a cam goes flat, the engine bearings typically get chewed up. The engine should be pulled out, disassembled, cleaned, inspected, and repaired (new bearings and crank turned).

I hope you plan on disassembling the entire motor for an inspection. All that metal from the cam is now dispursed thru every oil passage and bearing in the motor.
