9 Second Buick GSX Stage2 GS Stage1 9.51 @ 140
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.
Buick 350 on test bench
This is a fresh rebuilt Buick 350 runnin' on my test bench..
Got 9.8:1 compression (Speed Pro hypers & moly), rebuilt heads with good portjob, 470/470 lift cam, Poston aluminium Intake, 600cfm Holley, 1968 1.6:1 aluminium rocker arms, modified oil passages, timing cover and filter housing, oil balance tube on rear side, crooved cam bores in block, double roller.....and so on.
Let it run for more than 30min. with 2500rpm's to get it REALLY HOT (more than 100°C!), and to have a look on the oil pressure when running such high temps...with 15-40 standard mineral based oil..OF COURSE!
Huhh...32psi..at roughly 650 rpm's..did you expect this?
I DID!! Get your hands dirty and rebuild your good old Buick engine!!
HE IS WORTH IT!!
NOTHING pulls lika Buick engine!!
69 Buick GS 350-4 barrel
This is my bone stock, save for the demon carb( it is an original four barrel motor though) 69 GS 350, factory manifolds without mufflers because i'm installing headers very soon, with purple hornie glasspacks:D can you say irritated neighbours? I'm going to get the T/A manifold for it along with some 3.91 gears (it has a chevy 12 bolt posi) and maybe a cam, the aforementioned stuff with the longtube headers should be a pretty peppy car, these old buick 350's make a lot of torque, the way it is now it will easily brake both tires loose and melt them during a brakestand, with the open manifolds it will even lay a couple of 20 foot long strips just stompin on the gas, not bad for a stock converter, stock 3.30 gears and 3600 pound car, this paticular motor was rated at 285 hp (net) and 360 ft-lbs of torque from the factory, and I believe they had 10:1 compression. The buick 350 actually has a longer stroke than a chevy 396 big block it's 3.85", this makes for Alot of down low go, and a good starting point.
Twin Turbo Buick 350 Skylark Cruising
This is the turbo kit I sell in use! Taking the Tubs and Twins car for a stroll, and me nervously rambling like a moron. See the Buick's entire story and evolution at BurtonMachine.com.
