If it needs to be Charger related, a 360 or 340 would probably fit. Not sure a 440 would get in there, they are a large block. The thee carbs on top would be e problem too. Awesome, though a tough fit under the bonnet.
Also, why 245 and not 265? (my dad is a Charger man, I grew up with E55s, a factory R/T 2bbl and loads of others over the years)
