Default twin turbo 331 ????

I'm gonna start building up a new motor in the next few weeks, It'll be probably a 331 with Turbo Driven Concepts Stage 2x twin turbo kit. I'm looking to get any advice and opinions I can get before I start buying. I'm looking to get around 600hp (thats on weekends with high boost, I won't be running full boost for daily driving), will a standard H.O. block hold up alright with a main stud girdle? Also, what are some good heads/intake setups. I was thinking about going with GT-40x or trick flow heads and a GT-40 or Cobra intake. I'm still not sure about the cam, I'll probably get a custom grind from Crane. Any info is appreciated.

On a 5.0 with gt-40 heads/intake(box stock) and 1.7rr's, they made 525rwhp & 591ft-lbs with 13psi & an incon twin turbo kit(the one that comes with everything), so it is completly possible.

My best advice would be to ask the people who put the turbo kit together. They would probably know best what parts and mods will work the best for you.

Take care,
-Chris

Wow.....that thing is gonna RUUNNNNNNN.....hurry up and get it done....I want to see what times you get with it!!!! Just joking. Take your time, do everything right, and make sure you find a good combo for it. I don't know what to tell you about a twin turbo setup, not very knowledgeable in that subject....

First off to support that kind of hp with the stock block, even with the girdle, have it tuned by a professional or you'll be picking pieces up off the ground. With a 331 and twins 600 hp is easily reached. I'll give you an example of how much power a friend of mine made. He has the same kit as me except he has a 60-1 hifi instead of a T04, out of the box GT40 heads, GT40 intake, 30 lb injectors, 76 mm mass air, 70 mm tb, and a bigger fuel system. He made 411 rwhp with only 10 lbs of boost on pump gas through a hp robbing AOD. He's has and can run 20 lbs with race gas, although he's AOD didn't like the additioanl 10 lbs, if you get my meaning. I would feel safe in saying he would hit the 500 hp mark with the additional 10 lbs and race gas.

For your setup I would go with the trick flow heads or AFR 185's. For an intake I would lean toward a box style upper, I just don't think a GT40 and definately a Cobra will handle that kind of power. The stock cam and 1.7 rr are good for mid 10's, but since your spending the money for a 331 and twins, I would definately go with a custom cam.

Check out www.turbomustangs.com. We have links to all the turbo manufactures and as soon as the message board gets up and running, there are guys on there that know tons more than me.

Hope this helps.

I'd like to help, but I don't know anything about turbo's or superchargers. I'd like to know more too. I think I'll go and look at these sites,

Cartech and Downs Ford each have box upper intakes.

Your gonna be able to rev higher(top end) with a box, from what I understand. I've considered getting a box for my car, though the Holley looks appealing..
Anything over 500hp on a stock block is risky business. A good tune, as 91GTturbo suggest, is a must. You can ask 100 guys if a stock block will hold over 500hp and 50 will say it will and 50 will show you pics of a split or busted up block.

The block, with a girdle, will be fine. It's the pistons I'd be worried about. The picture below shows a piston after I magnafluxed it. All 8 were like this, and he was running 8 (real) pounds of boost. I see it alot on boosted 5.0's. It's usually caused by bolting a blower on a stock bottom end, which is fine as long as you don't start cranking up the boost. Anyway, make sure you get yourself a good set of well fitted pistons.

Take care,
-Chris

I plan on replacing the entire rotating assembly with a Probe or D.S.S stroker kit (forged pistons,crank,I-beam rods,etc). I see a lot of people using 306s' also, but I figure if I'm already spending the money I might as well go bigger now with the 331. I've heard 347s' aren't too good as far as reliability/durability. I've also heard negative things about Probe (coast high performance) like them sending wrong cranks,etc., so I may go with D.S.S., their stroker kit goes for around $1200-1300.

Good stuff Chris. How much boost do you think the stock bottom end can handle? Or what do you recomend?

No more than 6 pounds. Keep in mind I mean a real 6 pounds, not the numbers the cheap boost gauges, like the turbo t-bird factory gauge, allow you to think you're reaching. Put it this way, above 6 pounds with stock pistons will require at least 95+ octane, and should run on 100. Past 6 pounds is the point where I won't do the work unless the customer follows my recomendations, which include new, lower compression blower designed forged aluminum pistons, and a tighter bore. I also insist on a better flowing fuel system, from the pump to the injectors, as well as a boost retard ignition box.

6 pounds of boost, at sea level, creates 430 cubic inches of displacement in a 302. If they want more than that, they're going to do it my way, or have someone else do it.

Take care,
-Chris

Do you think I should be alright @8 psi for daily driving and a little higher psi every once and a while on weekends with the stud girdle/forged pistons/race prepped crank/I-beam rods?

You'll be fine, provided the compression doesn't exceed 8:1. 8.5:1 is doable if you have 100 octane fuel available.

Take care,
