Unfortunately I haven't checked in here for some time...
Nice battery of photos there, beater. Certainly it has potential. On the subject of the engines, I'm sure the 241 inch engine was the same block (25" long) as the 265. But a nice thing to do with it today would be to put a Hemi 6 265 into it. Or even a Hemi 6 245. Plenty of extra power and revs, likely a tad longer but not enough to make it a problem.
Of course, you'd have to source one from Australia or New Zealand...
