^ that was my next question.

 

any answers?

 

FWIW, my .02 cents

yes people have run "stage 3" cams on their street trucks.

however, you are basically just shifting the powerband higher in the rpm range.

you'll lose some low rpm power to gain some high rpm power.

alot of people think, stage 3 must be bigger/better than stage 2 etc.

well, bigger/better isn't always the way to go with camshafts.

crower states that their stage 2 blower cam makes power from 2000 to 7000+ are you really going to be turning your engine anywhere near 7000+?

no, so why sacrifice the power in the low rpm range that you'll actually be using on a daily basis in a street driven truck.

again, this is just my opinion.

I haven't driven a truck with or dyno'd back to back stage 3 versus stage 2 cams.

this is just the line of thinking I used when selecting my cams.

another note, I wouldn't look for any huge HP gains with either cam selection. Like long tube headers, cams are a lot of money for a relatively small gain. I'm not knocking them, I'm just saying that maybe they aren't for everybody when you really consider cost vs gain.

good luck.

P.S. as far as the will the cams break my engine question. that's anybody's guess. no, the cams won't break the motor, will the power break the motor? maybe. depends on your tune, the strength of your stock components, and the positioning of the sun and the moon on that particular day. but I will say that the added rpms you'll need to turn in order to take advantage of the stage 3 cams won't help the longevity of the motor at all. again, good luck.

 

If you plan to rev the motor high enough to take advantage of the cams,the stock rods will not like it. With my Stage III (N/A) cams in my L, motor feels like it downshifted when you reach ~4500 rpm until shift point or my self imposed ~6,000 rpm red line. A whole different rate of acceleration that you can feel in seat of pants. If you limit rpm to what stock rods can live with, you will not have a very wide power band and be a net loser on change. Keep the power band where you can use it.

 

Is the lope noticeable on a stock block with long tubes and high flows on a stage II cam?

 

Several of Crowers in HALO and a Comp that may be running Sunday, come to Burger n Fries at Hooters on Tues. and listen for yourself The amount of lope depends a lot on idle rpm and chip tune.
