Muscle Car Of The Week Video #45: 1970 Buick GSX 455 Stage 1 4-Speed
http://www.musclecaroftheweek.com http://www.facebook.com/musclecaroftheweek Here's one for the Buick fans... a 1970 Buick GSX 455 Stage 1 4-Speed in Saturn Yellow! Buick made 678 of these luxo-rockets in 1970, and they were certainly out of character for the Buick brand. Producing 360 horsepower and 510 ft. lbs. of torque, these capable street brawlers were running with the fastest Muscle Cars from any manufacturer. In fact, Motor Trend Magazine clocked a Stage 1 car tripping the lights in 13.35 seconds @ 105.5 mph in '70, fast enough to be called their quickest test of 1970. The Brothers Collection never disappoints, and it certainly appeals to all Muscle Car brands.

We originally built this car with Frank Urbinati back in 1996.It debuted at the GS Nationals where it won the GS Pro Street class races. It was also the 1st GS Pro Street class car to break into the 9's at the time.Thanks to Frank this project came to life. Fast forward to 2010 and the car has been taken over by Bob Ortolani,the car still looks great and Bob decided to bring it up another level. We were happy to have the car come back to our shop and to have the opportunity to work with Bob and put together the new powerplant. The video shows the results of our 1st day out to tune the engine. The 1st two passes were shakedowns to check fuel/oil pressures and get a feel for the new combo. By the 3rd run we had posted a 9.62 @ 138 hitting the 7100rpm rev limiter chip! The 4th run was a 9.52 @ 140. On the 5th run it went 9.51 @ 140.65! After a good cool down and a timing adjustment we were ready to try for a 9.40 run, launching right off idle the car gave us a nice big unexpected wheelie! The wheelie sure lookes cool but we know we can go quicker with a little more suspension work to straighten out the launch and try to keep the front down. We're sure it'll go into the 9.40's yet and maybe even 30's after everything is worked out.
