Dan the Man cars ?

Yeah that makes sense. I had a 383 68 Coronet/ 4 Speed it was a Magnum, but I took it up a little further than that. 383 would be a doggone good motor for you as a bonus
I can just see a 64 Dodge with a 273 under the hood dressed like a 235 horse engine. Nothing better looking than a 273-4 barrel. Here's under the hood of my 66.
