Built by Enthusiasts. Engineered for Mopars.

If you've ever tried to drop a big block into a classic A-Body or swap a slant six for a 318, you know the problem: the parts either don't exist, don't fit, or come from someone who's never actually done the swap. That's exactly why Schumacher Creative Services exists.

Who We Are

Schumacher Creative Services, owned by Chris Field a lifelong Mopar enthusiast with decades of hands-on experience building, restoring, and modifying classic Chrysler, Dodge, and Plymouth vehicles. What started as a passion for getting the most out of vintage muscle cars evolved into a mission: design the engine swap hardware that the aftermarket never got right.

Chris has spent years in the trenches — not just reading about these swaps, but doing them. That real-world experience is baked into every bracket, header, and conversion kit in our catalog. When you order from us, you're getting parts designed by someone who has made the same swap you're attempting, on the same platform you're working on.

What We Make

We specialize in engineered engine swap and conversion kits for classic Mopar platforms — A-Body, B-Body, C-Body, E-Body, and beyond. Our kits cover everything from slant six to small block and big block conversions, motor mounts, torque straps, transmission mounts, and headers designed to actually clear your chassis.

Every part in our catalog is designed and developed in-house, with fitment verified against real vehicles.

What Our Customers Say

"I love these things. They make changing the starter or spark plugs a breeze. They clear everything. Not surprised they are out of stock. 73 Challenger, 440, Slapstik automatic, power steering. Get a pair."
— Jan G., verified buyer | Big Block Mopar Tri-Y Under Chassis Headers ⭐⭐⭐⭐⭐

"Motor mounts fit perfect — very good quality."
— Henry S., verified buyer | '67-72 A-Body V8 K-Member to Big Block Kit ⭐⭐⭐⭐⭐

Our Commitment

We're a small, focused operation — and we intend to stay that way. That means every order gets real attention, and when you have a fitment question, you're talking to someone who actually knows these cars. We're not a warehouse fulfillment center. We're Mopar people, making parts for Mopar people.

Whether you're doing a full restoration or a weekend garage build, we want your swap to go smoothly. That's the whole point.
