Yes software is the same. The Super just has more inputs and outputs so I can add more things to it. These are also 8 injector units to support more HP, but the 4 injector units will work fine with those camshafts as well.

I run a 232/238 112+4 hydraulic roller in my 462. It idles near dead smooth with FiTech commanding my timing. The cams you are looking at will be no problem for a Sniper.

so would running the ram4 (041)cam with sniper and only 9.5 comp be ok or should i stay with little smaller cam

How big is the engine it's going in?

I ask because 9.5:1 compression in a 455 can be "doable" with a RAIV camshaft, however a 400 not so much.

400 .030 over running 6x-4 heads with dome pistons sounds like im better off with little smaller cam my next pick was 224/234 @.050 .466/.488 lift 114 lsa summit 2802 cam
or is this still to big

For clarification sake since this is about the Sniper specifically. The Sniper itself would be able to handle an 041 cam in a +0.030 400. That wouldn't be a problem.

The problem is sticking that cam into a 400. It'll be really soft in a 9.5:1 combination 406. Remember, when something like a RA IV Firebird was spec'd, that engine was more like 10.5:1 and required both a manual trans and a minimum 3.90 gear to be spec'd to the car.

Now an 068 in that combination would be pretty good if you wanted to stick with an OE style cam. I think you mentioned looking at the VooDoo 704 as well which I think would probably be a better pick.

Yep that's what I meant. I wasn't referring to the Sniper, just referring to the fact that the RAIV camshaft works better with some compression which in turn does help the car idle and produce more vacuum too, making tuning quite a bit easier.

the summit cam is close match to 744 cam also did think about vodoo 703
i think 704 has more lift than i want
