1971 Oldsmobile Cutlass "S71"

1971OldsHeader

 

The original owner wanted a 442, but the pricetag on a 442 was a little out of reach, so this 1971 Oldsmobile Cutlass S was ordrered new with every 442 option except for the 455 Olds engine. It's got the bucket seats, 4-speed, Outside Air Induction fiberglass hood, sway bars, disc brakes... and a 350 4-barrel. It's an interesting car, and here's where the journey back to greatness begins.

 



1971 Olds "S71" Chassis Boxing & Paint E-mail
The V8TV crew has been making improvements to the S71's chassis, namely adding reinforcing steel in areas where the original frame was "C" shaped to completely "box" the design.   This will help the chassis resist flexing and improve overall handling and traction.   One design modification was the need to re-engineer the transmission crossmember, as it no longer will use the original mount holes because their access was closed off with the reinforcements.    Once the chassis was welded solid and ground clean, it was treated to a single stage enamel paint coat in a satin-black factory appearing sheen.    

 
1971 Olds "S71" Chassis Clean-Up E-mail
After the chassis was media blasted, the guys took the welders, grinders, and sanders to the frame to clean-up what the factory left behind.    They welded up unfinished factory seams, ground off excess welding slag and started measuring to add additional steel to "box" the original frame for strength.    They also try out the new HTP micro belt sander to clean tight areas. 

 
1971 Olds "S71" Frame Media Blasted E-mail

   Here's some crappy camera-phone shots of the "S71" Oldsmobile's frame after returning from the media blaster today... we were pleased to see the frame is in great shape, with the original stamped numbers clearly visible on the rear side rail.   Soon, we'll be adding some supports and boxing this frame to give it some additional strength.  

 

 

 


 
1971 Olds "S71" Rear Sheetmetal Removal E-mail
Sparks are flying as we cut into the rear section of the 1971 Oldsmobile "S71" project.    We began by drilling spotwelds, then using an HTP plasma cutter to remove the large sections of unwanted steel in the wheelhouse and trunk floor areas.   Then, it was more spotweld drilling and seperating to clean the remaining flanges.    This is the dirty work.

 
1971 Olds "S71" Spot Weld Removal Blog 1 E-mail
Thoughts on disassembling the body on our 1971 Olds "S71" project.    This time, it's spotweld seperation 101.   We'll feature more on this topic when we begin the reassembly of this car using an HTP QuickSpot II spotwelder.   This time, we take a look at some of the disassembled panels and see how they came apart.
