Evolution & Tillman Speed are both just over the Commodore Barry Bridge in Aston PA & you have JDM up near Englishtown NJ.. I know there's a few more, but those are the only ones I can think of at the moment.
Tillman Speed turned my 4.6 into a 302 stroker. Their mechanic Mike is a great guy and he's helped me on his own time with tips and hints while I was doing some work on my car.
If you're just looking to do a swap and no in house tuning I've got a guy local to me who knows his stuff and is a die hard ford guy with 2 ford powered dragsters. Steve Everett and his shop is Everett's Specialty repair in Williamstown about 2 miles from my house. Going forward I'll be having him do all my work but Mike from Tillman speed is a great mechanic as well.
99-01 5.4L dohc 4v crate motor never been taken out of crate its remanufacured right from ford so its basically a brand new longblock so it has the heads cams block oil pan etc since its a longblock it does not come with intake or valve covers.
Found this locally but not if i am getting in over my head and out of budget.
Called Evolution but i need the engine first to see which way i am going.
