Will be adding more to this list soon!

Any possiblilities of a stage 3 in the works with 272º?

The 272º is the advertised duration at a specific lobe lift close to .000" because you can't accurately determine the exact 0 mark . The duration at .050" lobe lift is more of a baseline for cam specs.

Different companies rate advertised duration at different lifts. One might use .006 lobe lift, and one might use .010. That could make cams which perform identically appear very different based on advertised durations. This is one of the main reasons .050 lobe lift point was generally accepted as a way to compare cam durations.

So I would need some more about 272º camshaft you are referring to. IE: duration at .050" lobe lift, and total camshaft lift.

Camshafts are complicated and they make me go crazy sometimes lol

Ok, got the actual specs for the stage 2 camshafts:

ADV. Duration @ .006" Lobe Lift = 258°
Duration @ .050" Lobe Lift = 189°
Camshaft Lobe Lift = .247"
Valve Lift: .395"

Now if I were to use duration @ .002" lobe lift the degrees would increase to 298° So lets say the 272 camshafts had an advertised duration @ .005" or even .004". You can see how much difference there is in duration between my camshafts at .002" and .006".

I had a set of camshafts hardness tested and then reground to the MAX! These would be my stage three, but first I need to test them out to make sure they can be used with VCT.

ADV. Duration @ .006" Lobe Lift = 266°
Duration @ .050" Lobe Lift = 210°
Camshaft Lobe Lift = .232"
Valve Lift: .371"

So you can see what happens when you max out your duration, you start to lose valve lift, but your valves are open that much longer, which worries me with the VCT. These cams are going to have a nasty idle These camshafts are available for $840.00 Shipped. They are not advertised on the website yet, but you can purchase these.

Thank you for the indepth response. Yes cam info can drive one up a wall 0_0

I'm still in the blueprinting stages for my heads so not sure how aggressive I want just yet. Do you have the info for the valve overlap for stage one and 2?

No problem. Lol once you get to understand them, and what everything means it becomes a bit easier.

Sorry, I do not have the overlap specs yet. I'll have to sit down one quiet evening and figure it out.

Do you intend to put any of your cams that you offer into a vh45 and dyno it?

I just dropped my cams off at Franklin Cams in New Zealand:

To have a performance regrind done on them. I'm not thrilled about the reduction in base circle, but I've done some science in conjunction with my 3d valvetrain simulation regarding HLAs taking up the clearance, and the HLAs will still be within their pumped up capabilities. To be on the safe side however, the use of some HLA shims wouldn't be a terrible idea.

Anyway I'm going to put these cams + JECS 440cc yellow top injectors into my 4.5 stroker VH41DE with some mild porting and polishing, even length 4 into 1 extractors, and stock intake manifold. It will be dyno tuned and I will post the results when this happens (should be next couple of months if all goes well).

Awesome to hear, is this the main forum you post on or do you have a build thread somewhere else?

Looking forward to seeing your results.

Well Mettler...? Hows the engine?

I bought a billet fuel rail from you guys, thank you... very nice piece

I was looking at doing some valvetrain stuff, but I have heard re-grinds can wear down after a while...

We had the hardness tested on the camshafts after re-grinding and it was still good. Those camshafts that we had tested were actually ground to a more extreme profile than our Stage 2 camshaft regrinds.
