BRAND NEW AM GENERAL/GEP 6.5TD Long Block Engine with a limited ONE YEAR UNLIMITED MILEAGE WARRANTY AND FREE SHIPPING!!!! (*48 contiguous states)

Our Brand New engines are made by General Engine Products/AM General in Ohio, the same factory  that originally made them in your GM Truck. They still make them as replacements and upgrades and also supply the US Military with them for all Humm-Vee's you see on TV fighting over in Iraq and abroad.

Factory Fresh, ready to install. Include all the latest updates to the block and heads.

Why buy a reman when you can have BRAND NEW factory engine at almost the same cost!

Goodwrench sells these engines for $8000+, made at the same factory! We buy them as an OEM and sell them at wholesale prices.


A "Longblock" includes Shortblock (complete bottom end), Valve Covers, Heads, Oil Pan, Harmonic Balancer and Timing cover as pictured. Also all necessary gaskets to complete the installation! Does not include sensors/switches, injectors or glow plugs.

Engines are sold on an exchange basis and a $500 refundable core deposit will be required. Failure to return the core within 30 days will void the engine warranty. We need your core back to offset the discount price we sell this engine for.

If no core to exchange or shipping outside of the 48 states, the core fee is $1500.
