Had a lifter eat my cam. So..... I installed a TR CheaTR cam. Pretty happy with it so far. The cam that got ate was a TR 224. I also upgraded the lifters and lifter trays.

Mods:
- Thunder Racing CheaTR Cam
- LS6 intake
- Corvette Oil pump
- FLP full-length headers w/ 3" off-road pipes
- Dynomax Super Turbo Muffler
- TEA Stage 1.5 heads
- 3.73 gears

what caused the lifter to fail? age? high rpm? what are the specs on the cheater cam? what other mods do you have?

Pretty sure I have a lifter bad, I assume my cam is ruined . Luckily its a stock cam.

What caused it ti fail...... my guess is the crap LS1 lifters in stalled on these cars. It did show some wear on it from other lifters, but the #3 intake lifter had a flat spot on it from it failing. It wasnt real "gritty" (thank god) but was gummd up a little. So she got LS7 lifters with LS2 trays. For now I have put a stock tune back on it, and it seams to do alright. Its only been a week so far, more to follow. Yester day I did bump the idle up to 850 rpm..... but today I will reflash it back to stock. I bumped it up because of the slight shake it had..... but I kninda liked it. With the headers and 3" pipes I have..... there is no "cheater" cam about it... you can tell it has one. Running the stock tune the rpm was in the mid 600 range. I went with this cam because I wanted a streetable cam that didnt need a stall. When I bought the car in December, the guy I got it from just had the tranny rebuilt, and put in a factory stall because he wasnt sure if he wanted to keep dumping more money in it before he sold it. With the factory stall, and the 224 cam, it realy wanted to push through the brakes at the lights. So instead of getting a cam kit (Cam, springs, push rods) for close to $800, and dumping money in a stall (close to a grand).... I just went with a milder cam. My other option was the "old man cam" from thunder racing. But when I called them the sales guy kept pointing towards this one.

Best thing to do is spend a extra $130 for Morel link bar lifters instead of the LS7 lifters and lifter trays.

It isn't always the lifters fault. Cam hardening can play a role in a camshaft failure as well.

SideStep

EXACTLY! I had this happen to my F13 cam..

Hackscamaro

i have seen to many of these some from cam hardening and some from lifter failures. i had a ls7 lifter lock up in my lt1 and take out my cam. i have seen a few cam hardening issues at work as well as a couple lifter issues. on all of the new vehicles gm claims its the cam not being hardened properly. i had one come out of a truck that the lobe was completely ate off and only a circle left

I wonder what cores they use? Maybe Comp?

ep142

that sucks, I know the feeling it just happened to my ms4......just have to build it stronger, hoefully the new lifters and trys keep it from happening again.

ep142

did you say it was the #3 intake lobe? that is what wore on mine.
