Overview

The Dirty Dingo Motorsports DD-3550C is a set of LS adjustable conversion engine mounts designed for installing Gen III and Gen IV LS engines into older GM muscle cars.

Constructed from laser-cut, 1/4-inch 1050 high-carbon cold-rolled steel and CNC formed, these mounts offer strength and precise fitment. The slotted design allows for engine positioning up to 2-1/2 inches forward or 1/2 inch rearward from the original bellhousing location, securely holding the engine even in high-horsepower applications.

Each kit includes Grade 8 zinc-coated hardware and new cross bolts for installation.
Show original supplier description
The Dirty Dingo Motorsports DD-3550C E-Z LS Adjustable Conversion Mounts are precision-engineered for installing 1997-2013 Gen III/IV LS series engines into classic GM muscle cars. Manufactured from .250 thick 1050 High Carbon cold-rolled steel using CNC laser cutting and a custom large radius die press brake, these mounts are built for durability and precise fitment, even in high horsepower applications. They feature slotted adjustment points, allowing for engine placement to be moved up to 2 1/2 inches forward or 1/2 inch rearward from the original bell housing position. Designed for integration with the factory rubber clamshell-style mounts on your original frame, these conversion mounts are compatible with a wide range of transmissions including Powerglide, TH350, TH400, TH700R4, 4L60E, 4L65E, 4L70, and 4L80. It is important to note several fitment and installation considerations. These mounts may require the use of an aftermarket oil pan. They are shipped as raw steel and are not painted, though a black texture powder coat option is available. Crucially, these mounts will not fit DART aftermarket blocks. They are incompatible with Corvette or Camaro-GTO low mount A/C setups. Additionally, if your application uses a 1998-02 Camaro low mount alternator, the amount of engine adjustment may be limited.
