1967 Mustang Reactor

552hp with 535 lb.ft torque

ROUSH Performance, a leader in Ford Mustang upgrades, will showcase a very unique Mustang in their booth during the 2006 SEMA Show in Las Vegas. Dubbed "Reactor," this 1967 Ford Mustang Fastback took more than 2000 hours to build.
The gorgeous deep metallic green vehicle is owned by Doug Hoppe of Sioux Center, Iowa who commissioned the Ringbrothers to rebuild the car with one simple objective - to contend for the 2007 Good Guys Street Machine of the Year award.
"The Reactor is a car build that we are really proud of, and I know that Doug (Hoppe) is thrilled with how it turned out," said Mike Ring, Ringbrothers co-owner. "We did all we could with the car, and are very excited to debut it to the world in the ROUSH Performance booth at the SEMA Show."
