Pick my cam for me
Was gonna go 408 D1, but deal fell through so new system on its way. Same motor though other than dished pistons. Was gonna be 9.5 CR for S/C, will give a brief summary since I know some will ask.
To those familiar with Bandit1, its will be his system.
408 forged iron block
dished pistons, ported 6.0 heads yielding 8.5 CR
LS6 intake ported 80mm T/B - so far?
Cam - help me! info to come
PTS turbo kit
80GTS turbo, turbo blanket, all hot lines wrapped
4" custom mandrel bent exhaust system
A2W intercooler, rated 1500 hp
Snow meth injection
All the other goodies of coarse
Fuel - leaning towards dual intank system
braided lines, boost ref reg, rails, hot wire, 60#, etc. You got the idea!
Drivetrain
4l60-E, vig 3200, trans cooler, etc
moser 9, 3.50's, chrome molly d/s
Where I'd like your opinions is on the cam. It was best described to me to choose it last. In which is where I pretty much am. Not looking for a race car, but a street car/DD is the goal for now. My theory on this is that with such a big power combo, 408/turbo, is it really neccesary to sacrifice driveabilty, fuel mileage etc for a few more ponies? Is it that much different? I thought so until I dug up a bunch of old threads last night and got some different opinions! Right now I have 2 cams to slide in and both comp.
224/228 .581/.588 114 LSA, I got this for initial plans of going stock cubes and just so be it bandit ran this cam and made good numbers too!
230/238 .580/.592 115 LSA, I thought that this would be a better choice for the larger displacement but is it really necessary? With the smaller cam he got pretty fare mileage, would there be much difference in mileage in the bigger one? I think it would make better top end, but I only plan to spin to 6500 anyways. The smaller would probably be better for under the curve. He said at 6600 it kept pulling hard with 14psi+. I know it would probably be best to talk to a pro and get a custom one made. This isn't an option for me, so please don't reccommend. I only say that bc I don't think it would make that much of a difference, especially for the extra costs. Between these 2 its practically free and the smaller is already proven good. Tell me what ya think, thanks guys!

I'll throw out a few suggestions.
Cam 236/230 XER on 115 duration
Dump the snow meth kit and buy a www.alkycontrol.com.com kit.
For a street car I'd run an air to air intercooler. (expecially for meth)
4L80 tranny to take the power
Huge fuel system.
Easy 800-950rwhp and tq daily driver but cost some dough.

From my knowlege, I understood if you have really good flowing exhaust you could use a traditional split, in which I will have. Anyways, as for the a2a, I thought a2w intercoolers were alot better? I agree on the 4l80-E, once I turn up the boost or blow the current one thats whats going in. Not screwing around with the 60-E's all of the time. Double intank proven to support up to 1000rwhp, I am pretty sure thats what I am going to use. Easier and better for the street too I think. As for the power, yes definelty 800rwhp minimum. This kit pushed over that and not sure if I ever will but think if I wanted to I could see over 900rwhp. Thanks for the sugestions

We initially used our blower cam on this turbo Corvette. http://www.exoticperformanceplus.com...Car.php?car=26
The video will be back up as soon as we get a chance to do so.
Here is our cam spec's. http://www.exoticperformanceplus.com....html?item=679 Bob

with 800 rwhp the 4l60 will last to the next street corner. definetly go with a large front mount don't worry about cutting up your bumper it is never a problem. Are you gonna modify the PTS kit to accept a T-6 based turbo otherwise you will not reach your goals because of backpressure with the 408.

I think the t-4 based 80mm turbo with the 408 and a cam with run into backpressure problems around 650 rwhp you might not be able to take it much higher than that. That kit was designed for factory cubes or 364ci not a 408. You might want to sell the turbo and have the kit modified to work with a t-6 based exhaust housing turbo like a sx80 or larger or something along that line.

Well, yes it is a concern of mine but it should be awhile before that power level gets old for me if that's its max. I know that the guy before me had it over 800rwhp with no problems though, but I am sure I won't be running it that hard anyways. If it comes to it than I will upgrade later. Thanks for your input!
