This 1989 Pontiac Safari wagon was built by Three Pedals in Sterling, Virginia to test their manual swap kit for 1977-1990 GM B-bodies. The company calls the project “Shaken & Stirred” partly because of the shaker scoop which sits atop of a 6.2 L LS3 V8. The rebuilt engine features Mast Motorsports’ SS camshaft, wiring harness, M90 ECU with pre-calibrated tune, Comp Cams 0.080” wall chromoly pushrods, GM Performance intake, Total Seal’s gapless top ring set, and ARP connecting rod and head bolts. The engine put down 435 horsepower to the wheels through a Hays Dragon Claw 1150 twin-disc clutch, T56 Magnum six-speed, 3.5” aluminum driveshaft, GM 10-bolt rear end with an Eaton Truetrac differential and 4.10 gears.

LS3 wouldn’t have been my first choice, but it is a good solid engine that should serve very well for years. Their choice of vehicle was masterful. Their website says S&S puts 435hp to the wheels. Chevrolet performance website list LS3 as 430hp, a camshaft and tune brought it up, very nice indeed.Well played Grasshopper. 😎
LS7 would have been my choice. But that 10 bolt isn’t going to last long. They break like glass behind stock LS1s. I went through three of them on a bone stock 99 SS Camaro.
I believe the 10-bolt has upgraded diff and axles.
Still the weak point.
If this has the 8.5 in it then it can more than handle that power. Even the 8.2 10 bolt would be fine.
Hi thanks for the comments! We are running the OEM 8.5″ 10 bolt rear with no problems so far, with 4.10:1 gears and a Truetrac. The axle housing is the only stock part remaining in the entire drivetrain! We beef up these rears with ARP main cap studs and use Moser high strength axle shafts with ARP studs. We have lots of write ups and video on the wagon here – http://bit.ly/2tV8gIE
What kinda tires are on this bad boy?!
Hi Brittany. One of the company’s posts says Deluxe Wheels 20-inch wheels (looks like 15-inch steelies) and 20-inch Michelin Pilot Super Sport tires. In one photo it looks like 255/40ZR20 tires. You can view those photos here.
