1970 FORD MUSTANG MACH 1
There’s nothing quite like seeing a rebuilt engine come to life in a legendary car like this. It’s always a special moment when someone brings their vehicle to show us after a fresh rebuild—especially when it’s a cool Mustang Mach 1.
Providing a testimonial and seeing the final product is very rewarding.
“I have entrusted the Henson & Murray Engine Rebuilder team with rebuilding my fatally damaged 351W V8 motor out of my 1970 Ford Mustang Mach1. The team around Scott explained the process in great details in a language that can be understood by laymen like me. The team machined my spare 351W block, repaired and replaced bit and pieces of the engine and went to great length sourcing original spare parts overseas. All this was done in a timely fashion and the rebuilt engine was ready in less than a month. The motor is back in my 1970 Mustang and running stronger than ever! Thank you Henson & Murray”.
