intake question

generally from a performance point of view carb vs efi are usually pretty even. I think it really comes down to driveability and reliiabality if anything. Carbs are old skool, easier to tune due to their simplicity, and they offer great performance in ideal conditions. On the other hand efi setups cost more, are usually more complicated and harder to tune but perform great in all conditions due to the various input senors affecting them. If your staying n/a and live in an area where the climate is consistant a carb would be great. If you ever have plans of going with boost or have alot of weather variables a efi system would be a better choice because it adapts better. In the end it comes down to what kind of car your making (daily driver, weekend warrior, or trailer queen) and only you can answer that.

As far as fitting it should work but I would guess there would be some excess metal where the stock runners meet the heads that you had ported. You might need to gasket match the intake to the heads scribe it and remove some of the excess with a grinder (dremel) and finish it sanded smooth.

Look into a Tmoss ported stock intake if you want to keep the sleeper look

Or

Use an 1995-2000 V8 Ford Explorer intake. It is a cast version of Ford's tubular GT40 intake and flows 220cfm in stock form. The 95-97 models have an internal EGR that is a perfect match for the stock Mustang EGR system.
