Smeding Performance

The cam gets the glory.

The heads get the attention.

The turbo gets all the Instagram likes.

But none of it matters if the bottom end can't take the hit.

Start with a forged 427 LS short block from Smeding Performance, then build the engine you've been planning instead of the one you'll have to rebuild.

Because horsepower is earned from the bottom up.

900 horsepower.

880 lb-ft of torque.

91-octane pump gas.

The numbers are insane... but they still don't tell the whole story.

The polished 8-71 blower, dual quads towering through the hood, and that unmistakable supercharger whine announce your arrival long before anyone sees the car. Then the 572 unleashes enough torque at 2,500 RPM to make the pavement question its life choices.

This isn't an engine for blending in.

It's built for the people who want to own the loudest, meanest, most intimidating machine on the block.

👑 Be the reason the neighbors peek through the blinds.

406 cubic inches. 520 horsepower. Pure small-block perfection. 🔥
