Default Help me spend my money

Ive got the coin to get a cam package now. I'm not biased to any one particular vendor. Here are the car specs.
1985 Mustang Coupe. Maybe 3200-3400 lbs?
5.3L 2005 L59
Holley mid-rise intake
BG Mighty Demon 750 Mechanical
TH400 with FTI transbrake valvebody
FTI 3800-4200 stall with baloon plate
4.10 gear ratio

I want a max effort cam that is good with carbs and nitrous. I plan to spray 100-200 through a plate kit.

I have a set of virgin 799 heads to replace the 706's. I can mill them if needed but I do not want to spring for full out porting and polishing.

So, with all that said. what cam/spring/pushrod package would you go with?

What is the part number of that Holley mid-rise? Is it a single plane like the Victor manifolds or a dual plane like the Performer series?

It's the single-plane intake from Holley.

With your combo, I would run this camshaft:
http://store.cammotion.com/hot-stree...reted-camshaft
It is 227/237 duration on a 111 degree lobe separation with 4 degrees of advance and .595" lift. With this camshaft, you could mill the heads up to .020" and still have good piston-to-valve clearance. It will also work good with up to a 200 shot of nitrous.

The next step up in aggressiveness is the Junkyard Dog:
http://store.cammotion.com/junkyard-...plane-camshaft
It is 232/244 duration on a 111 degree lobe separation with 4 degrees of advance and .621" lift. With this camshaft I would not recommend milling any more than .010". This camshaft can handle a 200 or so shot, but may not be as quick on motor in your 5.3 as our Hot Street camshaft listed above.

For valve springs, this are our least expensive dual spring kit:
http://store.cammotion.com/catalog/p...cbfba573238628

These are an excellent premium polished dual spring with titanium retainers:
http://store.cammotion.com/catalog/p...bcc96c7f2ee712

Here are our hardened chrome-moly pushrods:

Default EAP Camshaft Choice

Hi Josh, I can use my EAP to be of help, this is a free service to LS-1 Tech members.

I too am very good at camshaft design, I do use Crower Cams as my grinder.
I supply a lobe file of my choice using Andrews Products design software. (my masters)
I can provide springs, retainers, etc.

One important item using EAP, a "model", is to predict Valve Float RPM.

Would you like my help ?

What Ignition will you fit ?

Lance

I've always been curious as to how you vendors figure out a recommendation when someone asks for a "max effort" whatever component to complement their obviously not max effort build rundown that it is supposed to go with. From my point of view it seems like a no-win situation.

Sometimes you just have to ask enough questions to get a clearer picture. In this case, the OP has a pretty clear picture. He has defined his setup, but has the limitations of a stock bottom end. So, those parameters give you a good picture of what "max effort" means in his situation.
