1970 BUICK GS 455
Named: Puff Burnlee
I recently purchased a 1970 Buick GS triple black with a 455, originally a 350 Buick GS, automatic TH400 transmission w/ a 12 bolt rearend. I had a 1970 Pontiac GTO Project car (THXWIFE) that I sold in September. I loved my GTO and it was my dream car but it was not a driver and would not have been on the road for a few years. So now I can drive the Buick and upgrade it as I go. I kept some of the parts that I had for the GTO such as 3:73 Eaton Posi Diff, w/ yukon ring and pinion, Dewitt Rad w/ dual electric spal fans, and CPP big disc brake kits (I have heard the poor reviews on here about CPP so I will see for myself). The THXWIFE 1970 GTO thread has been passed onto here, well kind of as my wife got me a custom license plate "THXWIFE"
My Buick is going to be a daily driver from late spring to early fall, so a cruiser. I am wanting the car to handle and perform better on the street.
Currently needing to upgrade the suspension and steering as the car does not handle well at all. Its a little scary. So I am looking into UMI, SC&C, Speedtech, Ride Tech, Hotchkis and etc.. I am trying to figure out what will work best for a cruiser street car, but handles well and has some performance. Also upgrading the steering, not sure what? Maybe a Lee steering box or a Jeep Grand Cherokee steering box.
Currently riding on Buick Rally wheels, 235/60/15 front and 295/60/15 rear. Plan is to upgrade to 18" all around or stagger to 17" front and 18" rear. Thinking for the front 255 - 275 (275 if they will fit) and the rear 295 - 305.
Wheel choices:
Boze Force - Standard w/ the titanium accent or gunmetal w/ polished/chrome or gunmetal w/ sating black and a polished lip (5 spoke look)
Rushforth Fuel - Chrome or polished (5 Spoke look)
Bonspeed Superstars - Factory look with painted accents
Bonspeed Huntington - Chrome or polished (5 spoke)
Intro V-Rods - Chrome or polished (5 spoke look)
Budnik Muroc II or III - Factory look with painted accents
I do like the look of 5 spoke wheels. But wheels are about a year or so away. The wheels will come after the suspension and steering.
Engine is a standard 1972 455 Buick with a double pump Holley. I will be replacing the Holley with a Rochester Q-jet 800 cfm w/ electric choke this winter. I haven't got into upgrading the engine yet as it its running great, but the plan will be to make the 455 a solid street engine with 500 + HP and and 500 + torque.
If anyone has any opinions or guidance to help me out, I am all ears. Especially the GM A-body and Buick guys.
Thanks,
Trent
