1963-1966 Chevy Pickup LSX Conversion Aluminum Radiator with Dual HPX Fans

In the early days of LSX swaps, you had to blaze every aspect of your LSX swap. Maybe the motor mounts didn’t position the motor with enough clearance for your headers to clear the frame. Then when you moved the engine backwards for the headers to clear, the A/C compressor crashes into the frame rail. Fortunately with the popularity of LSX swaps, that is no longer the case. Especially when it comes to the radiator setup for your swap.

This radiator fits directly into the 1963 – 1966 OEM V8 engine mounts and use the top upper hold-down.

Regardless if you’re running a 5.3L truck engine or a 6.2L LSA supercharged crate engine, Entropy's radiator will fit, clear the accessory drive and do a killer job of keeping your engine cool.

For the upper hose, the upper hose from a 1995 Mitsubishi Eclipse turbo AWD is almost a perfect fit. For the lower hose, the lower hose from a 1999 Silverado 5.3L is close and will require trimming to work.

This radiator has the correct size hose connections for a LSX motor and has the correct steam vent port for LSX swaps.

If you’ve been reading about your LSX swap and are thinking or tapping the water pump to run the steam vent back into it: DON’T DO IT! One of the best features of the LSX motor is the steam vent system, which is one of the features that allow LSX motors to run high compression or boost on pump gas.
