I have searched this forum and other sites but have not found exactly what I am looking for. I found tons of info and the T5 swap and info on the 5.0 swap, but have not found anything on the complete swap together.
I currently have a 64.5 Mustang with a 289 (original motor was 260)and 3 speed. I just purchased a complete engine and T5 out of a wrecked 91 mustang. I plan on installing the complete setup in my 64.5. I think I know most of the basics:
Taking EFI sytem off and going with carb.
Going with Hydraulic clutch kit.
Electric fuel pump.
I have a 28 tooth drive shaft that I will shorten if needed.
New transmission mount.
Find Headers that will fit.
Will be going with the Taurus electric fan conversion.
Some of the questions I have are:
Can I use the 5.0 belt and pulley set up (after I remove unwanted components)?
What extactly do I need to do with the oil pan?
Can I upgrade the Cam with the current set up for more HP?
You don't NEED to run an electric pump, most 5.0L covers can be machined to take a mech. pump and the early dipstick, or as was mentioned, you can swap on an early timing cover, but you can't run a 5.0L pump with a 65-68 and some other older timing covers, it will throw off the alignment among other issues.
The C4 yoke works, someone else mentioned that, you can also use a C4 speedo gear, trans mount, and speedo cable, and buy a T5 transmission crossmember for an early Mustang. You just use regular headers for a 65 V8 Mustang. For the oil pan, you need the 65 pan, pickup and dipstick and plug the dipstick hole in the block with a 1/8" freeze plug.
To run the 5.0L belt setup, a ~60" belt is the ticket for no PS, AC, or smog. For this, you'll need to stick to a 5.0L timing cover and use different rad. hoses if using a 65-type inline in-out radiator with the 5.0L water pump.
The Taurus fan takes some doing as the mounting setup isn't meant for older cars, so you might consider something else and check the depth carefully as well as early Mustangs need a pretty shallow electric fan.
The 5.0HO pistons will accomodate a huge cam if you want.
PS: Before I forget, if you use the 5.0 heads, you'll need to plug all the different smog holes.
