A few years ago there was a 1/4 scale Hemi available. TDR makes some very nice 1/8 scale engines designed for their line of Models. Revell makes a good quality Flathead V8 engine in 1/8 scale. There are others as well. The question would be, How much do you want to spend?
Rich In the 1.1 world those engines fit. It may take a different oil pan. but it should be workable to get you where you need to be with it. E-Rod engine packages were designed for this purpose.
The Revell 68/69 charger came with two engine options one was a 383/440 the other a 426. I also think the 68 Dart had a big block 383.Ross Gibson makes a very nicely done 383 in resin
