Love the lines of your classic GM Square Body truck, but find the original powertrain lacking in performance, reliability, & economy? Sure, you could convert the original engine to EFI or look to LS / LT swap it to bring things up to more current standards. But neither of those options is going to provide the torque, efficiency, & driving experience you get behind the wheel of a diesel. Here at WCFab, our business was started by working on and modifying GM Duramax Diesel engines for increased performance and we've always been passionate about Square Bodies - so bringing those two passions together only seemed natural. This kit provides you with a specially engineered set of heavy duty mounts that will allow you to bolt a LB7/LLY/LBZ/LMM/LML Duramax donor engine out of a 2001-2016 Chevy Silverado or GMC Sierra 2500 / 3500 HD truck into your 1973-1987 3/4 or 1 Ton GM C/K Square Body Truck Chassis (Chevy C20, C30, K30) to support your conversion project. CAD Designed, Precision Laser Cut and CNC Bent, and Professionally Welded Motor mounts bolt in to factory location on Square Body frame rail. OEM Duramax style exhaust manifolds clear the chassis. Performance aftermarket exhaust manifolds may require notching or additional modification to upper frame rail. No body lift required - engine height and placement keeps all accessories inside the engine compartment. Slight trimming of the cab pinch seam may be needed on some applications depending on turbo & down pipe selection. If your truck does NOT have a suspension lift, lower engine oil pan clearance/modification will be required. 4WD trucks with a suspension lift require no oil pan modification. Requires use of 1 ton style brake booster on cab. 3/4 ton brake booster will not clear. Recommended for use together with Allison / ZF6 Transmission Crossmember Kit for 1973-1987 GM C/K Square Body Chassis (WCF100177). Aluminum Radiator, Electric Fans, and Air to Air intercooler with core support mounting available separately.
