Engine Transplant

A 1985 3.2 liter 911 engine and a flipped 901 gearbox, built by Wes Hildreth of H&H Enterprises.

The power plant for the D'Ingianni Porsche 916 is a transplanted 1985 3.2 Liter 911 engine with only 50K original miles before the overhaul.

Wes Hildreth of H&H Enterprises in Plano, TX is responsible for building the engine and transmission. I left the 6-cylinder rebuild to a real pro with numerous conversions under his belt.

A custom designed air conditioner compressor mount was designed by Wes Hildreth.
