There are threads discussing all of this.

S3, S4, S5 cam comparison - SR20 Forum

yeah I usually go to this thread for cam info, and I tried digging up info on the Kelfords, but I couldn't read their data in the format they had it.

No its not that easy.

Changing stroke changes a lot. Easiest way for me to sum it up.

Like I've said before... yea shoul atleast build this w a ve block so you can have the oil squirters.. then do whatever you want with the head which I still don't understand... u really want the lope 184cs do have some lope..

But either way, id build it on a ve bottom throw a de head on. And then when you see the light, you can do the head swap and be all good.

kelfords site doesn't tell me their low lobe "lift" data... but they do provide duration, and its between an S3 & S4 cam in duration... (depending on intake or exhaust cam)

the Kelford big lobe's duration far exceeds even the JWT C3 cams...
