Fel-Pro MS9990 Bui 300 Eng65-67Int engine tool

Engine tool for 65-67 cubic inch range

This Fel-Pro engine tool carries the MS9990 designation and is built for the 300 series. It addresses service tasks on engines in the 65 to 67 cubic inch displacement range. The transparent colour lets you see internal alignment during assembly or inspection work. It ships new from the manufacturer and was first listed in 2024.

Mechanics working on small-displacement blocks

The tool suits professional technicians and experienced hobbyists who need a dedicated fixture for the 65-67 cubic inch platform. It is not for shops that only service larger V8 or diesel engines requiring different bore spacing. Buyers without a press or fixture stand should verify their workshop can mount the 300 series hardware before ordering.

300 series fitment for 65-67 cubic inch engines

The single specification that decides fitment is the 300 series designation matched to the 65 to 67 cubic inch engine range. Confirm your engine falls within this displacement window and that your shop runs 300 series tooling. No other size or adapter is referenced for this MS9990 unit.
