460 Stroker with broken cam

cdog · #1 (**permalink**) 09-02-2002, 09:31 PM

My 460 Stroker (533 cid) was running good.

Backed it into driveway, tried to start it, wouldn't fire. Distributor was turning, rockers not moving... (uh oh)

Pulled motor, found cam in 3 pieces. This is a hyd. cam not real rumpy, 1.8 roller rockers, not a real built motor, about 600 HP.

Any ideas what would cause a cam to completely break?

Thanks

cdod - catastrophic engine failure can be caused by an almost infinate number of things. We will need more details, but usially on the teardown of a engine the cause of a failure becomes self evidant. I don't think you will get many replys unless you include more detail of the failure. As a side issue, a cam failure on the shutdown of a engine such as this usially means most of the engine parts have been spared a high rpm self destruction. Your rebuild may be a simple one if you are lucky. LOL

What kind of cam? We had 3 Crane Cams break due to poor hardening....very frustrating.

The cam gear pin sheared... cam broke, took out 6 intake valves..

I will be rebuilding with a new solid roller cam. I am thinking of going to a comp cams magnum 292 grind or something similar. Anyone have any experience with this cam?
