There's been past discussions about what the valve lift is on our cams. Here's the skinny. These measurements were taken on the vtec lobe only at .000 lash.

Intake gross valve lift = .410 On the V-tech lobe @ .000 lash
Exhaust gross valve lift = .378 @ .000 lash
Intake cam lift = .244 (1.67 ratio)
Exhaust cam lift = .244 (1.56 ratio)
Thought this would be interesting for some. You get the rocker ratio by dividing lobe lift by valve lift. I will have some more specs, baseline, duration, overlap once webcams has my cams. Our vtec lobe is actually pretty hot. For my motor, I'd like to see in the neiborhodd of .450-.470ish intake and exhaust will be kept close to the vest. That may be a problem though as the stock rockers are weak and at that dream lift, more spring is needed and hence, stronger rockers needed as well. More to come. Possibility of coming up with a rocker for me that locks onto vtec lobe at all times. We'll see.

 

So you don't have any of the duration specs yet? Dang. I was curious. I'm thinking that may be 264 intake, and 280 exhaust may be benificial. At least that's what we do on the Evo's at my shop. Think that it may be similar results with your motor?

 

i have all the duration and cam lift for stock CL-S cams. sorry ThinJim, i think i was supposed to send this over to you. let me type it up or scan it.

 

No problem, send when you can as I'd still like to see the whole specs on what you have so far.

Anyone have the rod length of the 3.2 and also the rod length on the 3.5?
