Hey all, I am going to be getting a new engine built this winter for my stang and I am hoping for 300-310whp n/a. For the bottom end I will be using the stock block and crank with DSS pro-lite rotating assembly and ARP hardware. I was thinking about going with the AFR 185 cylinder heads, and Holley Systemax II Intake, running around 10.5--11:1 compression, but there are a few thing's I'm not sure about yet. First of all, what cam would work best with this combo? Would I need to go custom for the kind of power I am looking for, or would an off the shelf cam work fine? If so, which one should I go with? This car will be getting a 150 shot of nitrous some time down the line and will also be street driven often and taken to the track a few times a month, so I want it to be pretty streetable, but still have a mean idle and be able to pull like a freight train.
I am also wondering how good that set of heads and intake work together? Do they go good or bad together and are there any better set ups to go with/consider? I will be ordering the top end with in a week so I want to get this figured out asap!
Anyway, thanks in advance for the advice guys!

If your goal is 300-310 RWHP then your block with AFR 165's and a good intake is attainable with a stock cam and 1.7's. I have seen this combo before make in that range.

I would go with the custom grind, especially if you are looking at nitrous down the road. 300-310rwhp is attainable with an ots cam, but with a cam from a guy like Ed the car would be better all around. www.flowtechinduction.com 
I would consider an rpmII with the afr heads, just me though. A fresh high compression short block with the right parts is more than capable of 325-350rwhp fwiw.

How come you would go with the RPM II? I have heard the Systemax II is a better intake, but that is just what I have HEARD. Does anybody have a link to an article comparing the various aftermarket intakes?
Thanks for the input so far guys, keep it comin!

The rpm II and holley systemax are basically equal IMO. I like the holley more do to the fact its opened up for the bigger TB. 75mm vs 70mm. Of course you can open up the inlet so pick which one you like better. I'd suggest talking to ed c or jay allen for a cam. 350rwhp is pretty easy with what your planning but you'll need to spin it to around 6500. You'll see some deep 10's if your hooking hard!

Will I need to do anything special to the bottom end in order to safely get rpm's like that out of it?
