Ok i see you on line and i have a guestion i bought a 1989 mustang back in the summe with plans to build it. it was a 4 banger from the factory and some one took the motor out already when i got it, the body is in great shape i mean it looks good , interior was like new, and i only paid $300.00 for it.
But my question is, im wanting to put a stroker motor in it with a carb. how would i go about gettin fuel from the tank to the carb. i have asked everyone i know and they cant seem to know them selfs and this is the first mustang i have ever build. Could you please help me out.

The biggest problem with carb conversions is the fuel pump issue. The fuel pump used for fuel injected motors puts about 45 psi, which is way too much for carbs, so you need to bypass or remove the old pump, and use a conventional fuel pump on the motor (5-7 PSI). Do not even attempt to use the EFI pump.
You can either use an electric low-pressure pump (holley makes some good ones) or go with a mechanical pump. If you do go with mechanical, you will need a new timing cover to accomodate a mechanical pump, and a fuel pump eccentric (some roller motors have them, some dont). I've also heard that you should change the fuel line, going with 3/8" or larger line to flow better.
Youll also need a 79-85 throttle cable and brackets. V-8 Thunderbird parts work as well.
For ignition, you can use a distributor from a 79-85 302, or go with one of the mallory self contained setups.
Lastly, if you have an AOD (automatic) transmission, you need the throttle valve setup. If you have a manual, there is no change.
I hope this helps. Usually you don't want to do a conversion like this unless you have a really good reason. Going with a big cam and heads,with a big carb is a good way to get the most Naturally aspirated power, and this would be a good reason to do the swap. This will destroy your gas mileage on the street, but if it's a racer it's the power you're after.
Take care and let us know how it goes.
