Very nice Jay! You guys did a great job. Might be an optical illusion but that shifter looks pretty far back.

Jay that engine looks and sounds nice.
What kind of HP and torque are you getting out of it.

Dyno shows these at 420 to the tires. Have not tried a Boss version because the price difference does not make sense for this install with a custom tune. I like the potential of the new Aluminator 5.0 offerings though. We have a potential customer in MA that may go this route but the clock is ticking on registrations in MA.
You can wind these out to about 7500 or so rpm. Cold roads so I have not gone beyond 5500 today. Working on a drive video now.

Would this set up meet current tailpipe emission standards? Where is the catalytic converter? I know it is not politically correct on CC, but wonder what kind of gas mileage you would get. What a beauty!

We have a little different configuration if emissions tests are needed. The factory has a sidepipe with internal cats and we have to run a different tune but it will work.
I don't see why 44mpg is not realistic at highway speeds.

I can tell you that on my first FULL tank of gas, I got an average of 15.6 MPG. I think 20-25MPG is a little more realistic for freeway driving, after break-in.

I have the same engine, over 6g miles, best I got was 26mpg, 6 speed, 44mpg is laughable. This isnt a prius. Looks good.

The boss intake is suppose to be a good bolt on they say 50hp plus.

This car sports a 3.46 rear ratio, I plan to swap it to 3.91 LSD if the customer wants. The Magnum is a .7 .5 unit if my memory is working today.
The Boss intake gives up some torque, and I'd like to keep it.

You also loose 30 foot pounds of tq, not a good move for the street, tq gets the car going hp keeps it there. It does look cool though.

I know that Hollywood Hot Rods built the Raybestos 32 Ford and re-machined some 427 sohc cammer rocker covers for the Coyote. With a 8 stack system that would look awesome under the hood of a Cobra...

I switched to a 3.91, it is a must, the car falls flat in 3rd gear if you dont, fuel milage was not a affected, tell your customer it will be his best upgrade, it keeps that engine in the sweet spot at all rpm's.
