347 in a fox mustang

I'd skip the turbos and go with superchargers myself.. much easeir to implement on an EFI motor.. no need to go reprogramming everything to work with the forced induction like you need with turbos.

with a stroker motor I'd go with an auto trans, rebuilt to take the power. It'll do much better than msot manuals, and you won't burn through clutches on a monthly basis that still need a bionic leg to push in on every shift.

you'll need a new drive shaft, a loop for it, and a new rear end, like a built ford 9" with whatever gearing you choose to go with to match the transmission you pick. Have the same person build the motor and set up the tranny and rear end, or at least get people working together. If they don't all match up well, you'll scrwe yourself when it all goes together and ends up not working well.

you may also want to consider a mini tub on the rear with some drag radials (DOT) so you can actually get that 500HP to the street without jsut melting off half of your $300+ each tires every time you launch.

you also need to decide things like if you want a drag car or a car for curves.. they don't mix.
for handling you'll want to stiffen and join the frame, beef up the suspension, and use larger rims with lo pro tires.
for a drag setup, you want Caltracs in back with monoleaf springs, no sway bars, let the frame twist, and use tall tires with about a 17" or 18" rim.. 60 series rubber in back with a crinkle wall.

figure out what ya want the car to do, then plan accordingly.
talk to people who know fords and how to set them up for what you want. see what works best, and apply that experience and wisdom before buying parts.

that's how I got my car set up right the first time.. by spending hours and hours talking to other Mopar people about what does or doesn't work for my particular car.. saved me a lot of headaches.

no luck on the header panel for the crx its busted and he only has one. he mainly has older cars in there too.

im pretty sure ill want to stay witha stick i know a really good aod or something along that line would be great for it if its built right but i like the whole stick thing thats why i did the swap in the first place.

For doing the building part of the motor ill probaly just build it myself and have a really good machine shop do the boring and balancing and add some studs to the lower end and what ever eles has to be done. the tranny ill probaly just order to specs and talk to the guy doing it and tell him everything i want it to have. i dont know if i want to go with a 6 speed or a beefy 5speed.

i was thinking about going with a supercharger before but i thought i read somewhere that they were less efficent so then i decided i was going to go with a turbe but i might of read it wrong. they makepretty nice twin turbo kits for my car though.

that mustang is pretty much exactly how i want mine except differnt car and differnt rear end and wheels/tires. that actually made more power then i was hoping to get.

a turbo is more efficient because it works off of the exhaust gas pressure instead of a belt drive.
the drawback is you have to wait for the turbo to spin up, and you have to stay in the turbo's power band to get optimal performance, which means a lot of gear shifting trying to keep the RPMs up.

A supercharger takes a bit of power to make power, but you generally get more boost from a supercharger more easily by changing pulley sizes, the response is instantaneous when you hit the gas, even from a dead stand still, you don't have to reprogram the ECU the way you do with turbos, etc..

turbos are nice and all, but I'm a much bigger fan of belt driven blowers.
Roots style first, centrifugal second.

a blower is a lot easier to install as well.. no exhaust piping to route and heat shield for, etc.. a lot less work and a much simpler setup overall. less to go wrong.

im a big fan of motor only. i just dont get into power adders.

dont worry smoker my ranchero is all motor. i still am up in the air on my mustang though. i guess ill decide when im closer to doing it and have about 10gs to drop into it.

"im a big fan of motor only. i just dont get into power adders."

I like all motor too, but if you read that article, the guy gets 535hp at 620 lb ft of torque SAE Net, and gets 20+ mpg in town and near 27 on the highway. I could put up with a power adder for that :) Car can run mid 11s going by trap speed.

ya thats very impressive. get some nice meats on the back he could do alot better.

Some good sticky drag radials would be plenty for it. Width isn't as important, more for showing off. I like the stealthier feel of that car, though.

contact area means a lot with enough power.
look at the average differences in ET times between cars on drag slick ripple wall tires, and cars on street radials, then look at the difference in contact area.

No way I'd want my car on less than 10" of rubber in the back with a lot of low end torque.. otherwise you spend more time feathering the gas to stay planted than you do accelerating.

anyway you can do pretty much all you need without a power added with the right motor. I've seen a 440 from Indy putting out well over 1000HP, and a friend of mine has a 454 el camino with the stock motor, new heads, and a cam etc.. (basically updated the top half of the motor) and he's sitting at 570HP.

That's more than enough for any street car really.
