Yep! I drive it to work everyday, unless it rains. Like you said, it uses the 198 rods (I bought my set from Doug Dutra), and six KB hyper pistons from the 2.2 turbo engine (also went in with Doug on a "group buy" for pistons — we bought 3 sets, and split 'em in half). Yes, I brushed with greatness on this engine build!
My compression estimate came out to around 9.3:1.
Nothing much special about the engine otherwise — Super Six, Dutra Duals into 2" pipes all the way back, HEI ignition, Erson 270 cam (I think I got the last one from Summit before they went out of production, but Erson has since worked with Doug to produce some new grinds), and a 2600 stall converter from Edge. Still have a stock head (with upgraded springs) and the 2.76's in the 7 1/4 out back, but even so, it's a strong engine to me (but I may have low standards!).
It's got a couple thousand miles on it so far, and I've still got some tuning to do (once it starts to cool off a bit here in Tejas). Pulls 16-17 mpg in my daily commute, about 60/40 Highway/City. My future plans are/were a big valve ported head from Mike Jeffries, a T-5 tranny swap, an 8 3/4 rear with a decent ratio, and MPFI, but the Swinger was involved in an accident last Friday. It's still perfectly driveable, but the passenger side door and door frame are screwed, probably beyond (practical) repair. So, I may end up looking for another car to drop the drivetrain in.
Lemme know if you have any questions!
