If yes, what is your setup? Stock bore, big bore? Any problems with starting, detonation? How does your savage run? Any problems with rocker arm wear? Any problems with cam chain longevity? Are you also running the performance spring kit?

Lancer is only having the Stage 3 cam made these days, as it provides the best overall performance. I have been running the Stage 1 cam for the last 10,000 miles, and it works fine.

All of the cams made for the Savage are pretty mild - and none result in any starting/running issues.......they all work just fine in a daily rider.

I'd call that a problem. Yes, might be that I heard pinging once. Albeit, there’s many Savage owners running a DR cam in their Savages and haven’t heard a single complaint.

Too much cam would have the opposite effect, lowering the dynamic compression at lower rpm. That is why a V8 with a radical cam is hard to start when cold. It allows cylinder pressure to escape through the still open valve, and air velocity at cranking speed is too low to properly atomize the fuel. I would think that the Wiseco is the source of his ping.

I agree that more duration typically results in lower cranking pressure and reduces pinging. But that's all dependent on the actual valve timing. It is conceivable that the DR cam closes the intake valve earlier than the stage 3 and even earlier than the stock cam. How do we get the actual timing specs? I/O, I/C, ITDC lift, I max lift, E/O, E/C, ETDC lift, E max lift. It also might be possible to retard the cam timing about 4 degrees by repositioning the sprocket on the cam. That would improve the pinging situation.

I don't have the exact opening/closing specs for the DR cam, but the duration is essentially the same as the stage 3 cam, just more lift.
Stock is .254"/,244" with 224 degrees@ .050.
Stage 3 is .273"/.273" and 238 degrees @ .050.
DR is .345"/.355" with 238 degrees @ .040.

Either the DR or stage 3 would be a considerable improvement over the stock cam. The DR will show bigger gains from port work and less restricted intake and exhaust though.

Lancer has looked it over....there is a significant difference and he determined it was not doable.

No kidding. I hadn’t heard of that option. Nicer priced option vs webcam.

I have been watching eBay for used DR650 cams......there are plenty of later model DR cams - but a usable early cam that will work in a Savage engine is very rare.

This style cam with the compression release is for the later models and it will not fit the Savage engine.
