I picked up a 70 Cutlass S this year. Needs a lot of work but getting there. I am turning it into Doctor Olds mileage machine this winter, already getting 21 mpg imperial. Using the Olds 260 that was in it, the nice TH2004R from the 88, higher stall and all with the factory 2.78 gears for next year and finishing the interior as well. That QJet you did will stay with my 88 Cutlass as I gut the interior and finish the 403 stroker and turn it into an 1/8 and 1/4 mile car. That 84 Hurst/Olds is the car I should have bought instead of my 88. Good part on my 88 is it has no value so I can do what I want to it. Good luck and enjoy.
