Overview

The Dirty Dingo Motorsports DD-3550C is a set of adjustable engine conversion mounts designed for installing Gen III/IV LS series engines into older GM muscle cars. Constructed from .250 thick 1050 High Carbon cold-rolled steel, these mounts are CNC laser-cut and press brake folded for precision. They allow for engine placement adjustment up to 2 1/2 inches forward and 1/2 inch rearward. Each kit includes Grade-8 zinc-coated hardware.
Show original supplier description
The Dirty Dingo EZ Adjustable LS Conversion Mounts are precision CNC laser-cut from .250 thick 1050 High Carbon cold-rolled steel. These mounts will allow you to move the engine from the original bell housing position up to 2 1/2” forward and 1/2” rearward, ensuring secure engine placement even in high horsepower applications. Each mount is manufactured using a precision CNC press brake with a custom large radius die to minimize stress on bends. The design accommodates a range of standard or automatic transmissions, including Powerglide, TH350, TH400, TH700R4, 4L60E, 4L65E, 4L70, and 4L80. Important considerations for installation include that these mounts may require the use of an aftermarket oil pan and are sold as a pair (left and right). They are shipped as raw steel and are not painted. These mounts will not fit DART aftermarket blocks. The "D" denotes the driver's side and "P" denotes the passenger's side, with arrows pointing forward. While these mounts will clear LS Truck spacing low mount A/C, they will not allow the engine to slide back due to mounting against the A/C compressor bracket, effectively pulling the engine 2 1/2" forward from the original bell housing position. They are not compatible with Corvette or Camaro-GTO low mount A/C. If your application uses a 1998-02 Camaro low mount alternator mount, the amount of adjustment may be limited.
