This is a mounting solution for the supercharger water pump supplied with the LT4 crate engine (part# 13597903). With this bracket you can bolt the pump to the engine block on the front drivers side lower position using the two lower threaded holes near the oil pan. Or, if desired you can use the supplied aluminum spacers to mount it 2.25” higher on the top set of threaded holes (see image in gallery). The construction is .125” 4130 chromoly for longevity and it comes fully tig welded. You will need to file one factory clocking tab on the pump’s rh mounting wing about 1/8” for flush bolting.

Approximate placement shown with tape measure in pictures referencing the engine block. Please inquire for precision specs if you believe it will be a tight fit. I’d prefer to help you on the front end then sell you a bracket you can’t use.

*The images used are of a 3d printed prototype to demonstrate the design, the final bracket design is subject to change.
