There is a lot of people on here who hide behind these keyboards. Its their comfort zone. They have nothing better to do than spew negative things an hate. Makes them feel powerful! HahahaaaaaA group of Mustang enthusiasts treating each other with disrespect, and animosity truly represents the ugly side of internet/forum behavior. Catch a clue fellas, really not all that difficult to discuss our hobby without hurling insults. Sign of the times? So much hate in the world, I would suggest some reflection before travelling that road.
Moss will gladly port an upper, requisite welding and all, but he will try to steer you to a manifold that will better suit your application. It will cost quite a bit more than the vendor being talked about here, it seems to me that Tony does offer very good value for the dollars spent. I would prefer if they used the industry standard 28" depression flow numbers, I'm not sure that flow numbers scale all that well as velocities get into higher ranges, but I'm certainly not an expert.
I point blank asked that guy to port the upper..
He doesn't offer that option. You know, you can't impress the world. This post is to let others know who work for a living, there is options out there.
Hope you have a great day.
