Most people do heads/cam together so it's going to be hard to see the gain from a certain cam shaft. Call Greg good and he'll be able to answer your questions.
Yea, not much dynographs on builds here. You could possibly have one of the tuners like AC, or ViperSpecialty email you the .DRF files for a car with a similar setup to what you are interested in than download WinPep from the Dynojet website to open the files and view. However, im assuming they use dynojet, so if Not than my idea might not work as i dont think the other brand dynos have free download of their viewing software.

I our very popular friend "Twister" had a cam-only thread. He had some details.

I'm so tired of reading Twister's threads
. I've found his posts on pretty much every Viper forum known to man. His stuff seems to be the only thing that comes up when searching. Oh well, I guess I'll just have to speak to the vendors.345s-bspinnin

He stands out because he is the only one who chose to ignore all vendor suggestions about pairing better flowing heads with an aftermarket cam. He still made some decent gains, but is probably missing about 75whp from a set of better heads.
Did he ever end up going with a set of ported or aftermarket heads? I think his final numbers were ~550rwhp which seems kind of low for a cam and head upgrade.

There is a couple of Srt 10 Ram guys that have done just a cam swap with results. I'll try to find a link for you..
If you're going to go with upgraded heads, then a before/after on just the cam (with the stock heads) won't necessarily tell you what you want to know though. The cam that works best with OEM heads may not be the best for the flow of the aftermarket/ported heads.....
If memory serves it was running around 12.1at 119 mph stock and 11.4 @ 126 mph with the cam and 550 rwhp.
708 cam is a good performer. cam alone with no other mods is worth 30-40 rwhp. with supportings mods then 100 in my case on same dyno

Like I said above I just want to see some dyno graphs
. That was what was great about owning a Corvette: there's a ton of information out there and a dyno graph available for pretty much any combination. I know, I know there are a boat load more Vettes than Vipers, but it seems like everyone here just likes to talk about mods without anything to back it up (except for a few people).Oh I am! Doing it all at once so I don't have to tear everything back apart.
