1971 Oldsmobile Cutlass "S71"  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. Our transformation includes building an Olds diesel-block based stroker motor with the help of BTR Performance , a Bullseye Power turbocharger, FAST XFI fuel injection, a Tremec TKO 600 5-speed, and a pro-touring style suspension and brake package.

 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.

 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.

 Just a quick update from the shop... Kelle brings us up to speed on the chassis and the body moving from the Autotwirler to the body jig we built. Next up: Tearing the rear wheel wells out, the trunk floor, and the rear tail panel prepping for new steel!

 We're beginning the bodywork on our 1971 Olds project, and we're trying to save all the original steel if possible. This time, we're patching the lower fenders, as these cars - all GM "A" bodies in general - seem to have rusty holes in their fender bottoms. The design allowed them to hold leaves, pine needles, and dirt at the bottom of the fenders, and this debris eventualy rusted them from the inside out. We obtained some patches from YearOne, and today we're cutting out the old and installing the new. We fabricated new supports to replace the rusty backside braces to keep the rust away for good.

 Here's the 350 in all it's taken-apart glory. After a degreasing bath, this block and oil pan are headed out to BTR Performance where Bill Trovato will work some machining magic and reassemble the mild 350 into a turbocharged street terror. Actually, the turbo motors allow for relatively mild cams and compression ratios, so the engine will still be pretty mellow, just much more powerful.

 We finally got around to disassembling the original 350 engine from the S71 Olds project. We found a pretty significant amount of sludge, but no major damage at this point. This engine had never been apart before, although it appeared one valve cover gasket had been replaced, as one side was clean and the other was pretty grungy. It's another example of why you want to run synthetic oil! However, seeing that this mill dates back to 1971, some gunk was to be expected.

 The bottom of our Olds project looked pretty scary when the car was assembled on the lift. However, after a foamy bath in Eastwood Under Gone undercoat remover and a shower from a pressure washer, we learn that the floors are in very good shape. The car needs a little wheelhouse repair and some trunk floor attention, but not as much as we thought.

 Our 1971 Olds Cutlass S project begins with the disassembly of the car. The Olds is pretty crusty, but we're tring some new techniques to restore the parts and keep it as original as possible. One example is reusing the hardware after it takes a tumble in an Eastwood Vibratory Tumbler. The tumbler is a great way to clean parts without any effort from you. It's cool.

 We pulled the Olds engine off the chassis for a look up on an engine stand. These Olds 350s are interesting engines, and we're developing our turbo scheme to make big power with the original engine. The original owner claims the clutch was never changed in the car, and it still seems OK even after 136,000 miles!
