Here's what I'm trying to work with now.... I want to say it's a 1980? Aspen...... Aint the best looking style car, but hey, it was free.... Anyway, I've been trying to find this answer out for a little while, but no one seems to know for sure, what body is this year Aspen? Anyway, what it is right now is a car that sits around with not much of a purpose. From the factory it is: 2 door, blue interior/exterior with front/rear bench seats, and a colum shifter. It is a Slant-6 with auto tran's and what ever rear axle. Now it has AC, power steering and power brakes.... It has front disc brakes. Any questions so far? Like I said, not much of a purpose, and is far from anything power wise performance. What I'd like to do is based on some information that I saw somewhere once, these cars came with the 6er, a 318 and a 360, other than this though..... Anyway, what I'd like to do is get ahold of a 318, change a few things, and put it in this car. Now I would like to run an A-518 (unless I am mistaken, this is a 4 speed automatic tran's, right?), and an 8 3/4 rear axle 489 case with a 3.73 gear (if it's a 4 speed tran's). I'd like to try and keep the AC, and the Power Steering though..... Being that I'd be going from an Slant-6 to a sb 318, I'd have to change the exhuast, I would want to run tubular headers, an X pipe, and small sized mufflers (I was thinking maybe the Flowmaster Hush Power 2 mufflers, or something like those). Then there's the oil pan, depending on body style, will probably depend on what oil pan will be used, but I'd want an 8 qt though, and a high volume oil pump. Now, being the car has a few electronic items on it as far as ignition and all, I'd probably run an MSD set up. There will more than likely have to be aftermarket gauges b/c of what year the car is and all.... That's just a little bit of what I'm looking at.
