Big update on our Ford FE to Small Block/Modular adapter kit 🔥

We completely reworked the design—no more compromises. Instead of a one-size-fits-all approach for both FE and Y-block, we’ve split them into dedicated, purpose-built adapters for each platform.

Here’s what’s new:
• FE adapter is now just .50" thick
• Y-block adapter is 1" thick
• FE kit no longer uses a crank adapter
• Now includes our in-house designed/made flexplate that bolts directly to the crank—fewer parts, less hassle, cleaner install

Not only are these new designs thinner and more efficient, they’re also less expensive to produce. And we’re passing that savings on to you.

💥 New price: $895 + $24.99 shipping (lower 48)

Better design, simpler install, lower cost. That’s how it should be.
