Thanks for replying!
I found according to Megacycle in their catalog
In. 400"/245* duration
Ex 435/272* duration
Hard to believe they would be off on their data that much.
If that were the case that would be a big change by swapping out.
I will call them see what they say about it.
If not only way I can know for sure is to check them myself with a degree wheel and dial indicator.
I find out for sure I'll post here so every one can know. I remember Ace asking it, as well as couple on Oz Firestorm.

 

Yep, Mega cycle is way off. Otherwise they are very knowledgeable and pleasant to talk with over the phone, I think the catalog number is a misprint, though I didn't bother to ask. If you dig around I posted all the numbers for all known cams that I could find, either way when I sent mine to Web they analyzed them and the timing events are 20/45/50/15 and the lift is 405, 405 CL is 102.5/107.5 and 35 of OL. But!!! This is measured by Web cams...Mega will come up with another number and so will everyone else depending on how they are measured and how much wear etc. I always measure from seat to seat regardless of what the manufacturer claims and I measure lift with a dial indicator at zero lash. Even then I will likely be different from the next guy who has a different mic/gauge/setup. Either way the published numbers are close to reality and don't differ much. Based on the flow test I did lift is not too important for the V as it reaches 90% of peak flow by .300 lift. After that it's still flowing but only slightly more so all gains will be up top, not a bad ting but in some cases you have to grind the caps for clearance and you will be noisier and wearing out the valve train faster. Based on that I'd increase the lift only slightly but focus more on duration and overlap. An adjustable set of sprockets would allow for you to indicate in the cams a bit better regardless of what you do. For example, my regrinds can be dialed in to be almost identical to the RC51 oem grind which is 20/50/50/20. Swap in some RC51 springs and buckets you have a potent little combo with oem components that are very reliable.
