That does not leave me much room for a 12" x pipe, looks like I'll need to make a crossover. I am gonna do Sanderson shorties mostly because there just ain't enough damn room.

Which one are you looking at , And so they need an adapter ( I keep reading about 2v adapter and not sure why)

Apparently the port is configured for 4V style ports so you need copper plates for sealing. The primaries are 1 7/8 so a little larger than the 2V but not to so large as not to seal with the proper gasket. Those are the Sanderson F150 specific headers and from the reasearch I have done end up fairly close to the stock location, the main issuer is they do not leave a lot of room for a reducer flange on the passenger side so I'll have to have some flames made up at an angle to clear the floor. Here is the copper plates required to seal around the smaller 2V port, the collector is 3" so I am going 3" into my resonators then all the way into the muffler dual inlet.

So would I need the opposite? I have 2v heads and the shorties are for a for a 4 barrel cylinder head. (I'm trying to learn about them)

Here is a pic I found of the passenger side, looks like a tight bend to wrap around the bell housing .

Drivers side looks like it would go smooth enough.

I think with the taller M block deck the header would be a little higher off the frame rail as the engine pictured is a Cleaveland short deck and the chassis is a CB.

The 4V ports are monsters, my FE intake adaptor is something in between 4V and 2V. The 4V cylinder head was primarily used on the Boss Mustang and Pantera engines and were only good for 4000 plus RPM, they did have the advantage of having the smaller closed combustion chamber though. The only 2V stock closed chamber was the Aussie head which can be found bare for about 600 bucks but will require hardened seats, guides and some blending of the bowls to be used with modern unleaded fuel.

Here is a basic view of the 2V port configuration on my adaptor plate.

Here is a side by side comparison, the 4V is just plain a monster.

I currently am weighing in on going aftermarket pre prepped heads from Edelbrock or going Aussie heads. Either way a 2V port can support far more CFM than I will ever use on my M build. My FE however requires more air and will be port injected to allow more air to be stuffed in the same size port being a denser air charge lacking the extra volume needed for the fuel. Also I will need 1/3 more air to feed the alcohol mixture of E85 so CFM requirements are much higher, I am looking for 325 CFM for the FE. On the M block I am looking for a base line of 275 CFM to keep velocity up for low end. I have a stick behind the FE and a C6 behind the Modified also so that will make a difference also in my power band along with gearing. Basically I am using nearly the same port but taking away the fuel from the incoming air charge for a denser mixture which in the modified won't be critical as demand is much lower and velocity is more critical than volume.

Feet would get a little warm with those headers LOL.

Looks like a T56 behind it.

Decided to work on my battery cables with what I had laying around, not sure if they will be heavy enough LOL.
Those are Number 4/0 welding cables.

Replaced the connector and greased everything up. Reused the motorcraft pickup, hey it works and saves me taking the distibutor apart.

Moved to coil over to the other side, coil wires could have been longer but used an FE bracket. Had to tap the t/2 hole in the intake to mount the coil bracket.
