... the 1970-'71 198 gave better driveability than the 225; the Carter BBS carburetor, used on the 198, worked better than the Holley 1920 they put on the 225 in those years)
Encouraging, since my 64 225 slant has a BBS. It idles so smooth you can hardly tell the engine is running. I fought w/ a 1920 in my 69 Dart for decades before I finally got a good one that made it run perfect.
198 in^3 (3.2 L) is not small compared with many current engines. It may even be better after turbo-charging than a 225. Most turbo'ed engines are much smaller than their NA brethren, say 1.8 L vs 2.4 L in a 4-cyl, yet produce more power and performance. Add MPFI and electronic ignition and 3.2 L should more than suffice for such a light car.
