Understandable. Dezod is working on a shortblock program for those that didn't know.

[bdis3]

i will probably be getting it.

[Redneck4csa]

Of course you will! lol. It's just too bad that Paul won't release any details for a couple of weeks.

[bdis3]

i know. I need to know the detail so i know the info about it. I may just build my own. Idk.

[Redneck4csa]

Well, let us know either way.

If you were to get the N/A cam and then get boosted later would the two work together. And if you were to get the stage 2 F/I cam would that work at all with out a turbo? Im not up on the workings of the engine internals

[punk2m1d]

Good question. Interested. Waiting for response.

[navylife59]

Yes and yes. The only difference is in the duration of valved overlap and lift. A F/I engine would benefit from the N/A cam because it's profile is more than the OEM cam. It would be more like a Stage 0 turbo cam as it does not provide the added benefit of a symmetrical duration. Remember, with a turbo you are trying to build up cylinder pressure and not so worried about evacuation.

A N/A engine would benefit from a turbo cam as it has increased duration and lift over OEM. Of course, not much is going to be gained on a purely stock motor or even with just I/H/E. Also, N/A on a symmetrical cam duration will not get the added benefit of evacuation from valve overlap.

The following info is directly from Brian Crower's website.

Adv. Dur. Dur @ .050 Lift (in) Lift (mm)
264/256 218/214 .385"/.363" 9.78/9.22
272/272 222/222 .401"/.401" 10.19/10.19
280/272 229/222 .415"/.401" 10.54/10.19
248/240 212/200 .385"/.355"

Stage 2 N/A
Stage 2 F/I
Stage 3 N/A (Race)

In short, yeah you can run it if you are planning on a later upgrade. You will find, however, that using an incorrect profile for your motor may give lackluster results.

[punk2m1d]

So a n/a engine would benefit more from the n/a cam upgrade? Make sense.

With i/h/e would you need the valve springs kit? Or could you just go with the cams for now?

As for instal: Is it a simple drop in?

[navylife59]

Simple drop in? No
Valve Springs needed on stock motor with I/H/E? No
N/A cam for N/A motor? Yes

The cams can be replaced w/o removing the engine but caution not to drop anything into the engine or let the timing chain go slack and thus possibly go back on the wrong tooth on the crank sprocket throwing the timing off. If your lifter buckets are worn, you will have to replace them with the correct length ones for zero valve lash as these are mechanical lifters.

I was too lazy to read the whole posting, but has anyone bit the bullet and bought the cams? if so was the engine N/A or not. I'm real curious how the stage 2 N/A cam helps, Does the redline get raised some? Im guessing the peak power is at a higher rpm with the new cams..? Worth $600?

[rbrick220]

correct me if i'm wrong... but the cams should only adjust your power band of what you get and when. and yes. a bit more of it. that being said, the cams should not adjust your rev limit... to do that you need the springs and valve kit. for BC's mouth, the spring valve kit is rated over 9000 rpm and will allow for the stage 2 cams. if you're staying stock valves and springs, you only want stage 1 cams. they estimated power gains around 20hp. if thats the case, its $30/hp which is great. but i'd love to hear from someone that's put them in a NA car

[navylife59]

I have the Stage 2 cams for the S/C that have been in my built motor for nearly a year now. Unfortunately, that motor has also been a floor show piece for Jotech Motorsports for that time period (at my request) so it has never been fired up. I have no place to put it and no plans on installing it anytime soon.

rbrick220 is absolutely correct on his post about the rev limiting and need for upgraded valvetrain.
