Description

1978 Datsun 620 King Cab Pickup – VQ37VHR Swapped, 6-Speed, Custom One-Off Build

Clean Florida Title | Located in Fort Pierce, FL

This is a 1978 Datsun 620 King Cab pickup with just a few upgrades...

Let’s start with what matters: this truck starts with the push of a button, it drives, stops, turns, and it’s reliable. You’re not buying a project that needs months of work before it’s usable—this thing is ready to rip as soon as you are. The only work left is cosmetic or personal preference—like customizing the interior to match your own style.

This is the first known 620 with a properly fitted VQ37VHR swap.

The same legendary 3.7L V6 used in the Nissan 370Z.

This low-mile VQ engine and 6-speed manual transmission came from a 2008 Infiniti. It was professionally installed with longevity, reliability, and serviceability in mind—no hacked-up shortcuts, no corner-cutting. Everything is thoughtfully laid out so you can maintain and repair it in the future without needing to tear the whole truck apart.

???? Built by Builders, Not Tinkerers:

This is not a hobbyist project and not slapped together with eBay parts. This truck was built by a professional fabrication shop with nearly everything custom-made in-house. If it looks one-off, that’s because it is—most of what you see doesn’t exist to buy.

???? Performance & Fabrication Highlights:

• VQ37VHR + 6-Speed Manual Transmission (from 2008 Infiniti)

• All 4 corners upgraded to Nissan 300ZX Disc Brakes (via Nissan Hardbody spindles)

• Chase Bays brake and clutch system w/ custom stainless lines

• Custom-built front control arms on QA1 coilovers

• Mustang II manual steering rack

• Custom 4-Link rear suspension with QA1 coilovers

• Custom stainless headers & full custom exhaust

• Custom aluminum fuel tank with hidden filler (check the pics!)

• Custom firewall & tunnel panels for easy engine access

• Digital Mako dashboard and control center

• New wiring: ZFever engine harness & Painless body harness

• Electric fuel pump

• Volk Racing 16x8 wheels

• Rear-mounted radiator

• Tons of custom metalwork throughout, including small details like the Datsun rising sun emblem stamped into the lower quarter panels.

This truck is titled, registered, and driven in Florida. Clean title in hand. It does not need a tune-up just to run, but it will benefit from a professional tune to fully unlock the VQ's power according to what you want from this vehicle. So much potential ready to be unleashed!

⚠️ DO NOT SHOW UP UNANNOUNCED. We’re a fully operational fabrication studio, not a car lot. We don’t have time for surprise visits or stories about how your uncle had one "just like it." Book an appointment and we’ll show you around properly.

This is a killer machine built with care and creativity. If you're into high-quality, wild custom builds—you won't find another one like it.

Cash is king. The minimum offer setting on this listing is NOT the bottom-line negotiating point, it's simply to weed out the dreamers. You can offer that low amount all day, but until there's money in front of us, it's all pointless banter.
