273 Stroker, 4.00" Crank

Take the forged crank and adjustable rockers from the 273 and throw them in a 318 for a lot less money and go faster :D :burnout:

Or...just build a 340 or 360. Considering mine is pretty mild and it made 470/455 and still has 13" Hg vacuum at idle with 9.7:1, I'd say they work. I'd have a whole 10ci on a 4" stroke 273 and easily 140 more HP. Head flow matters. Without going 4 valve heads, the small bore will kill airflow.

This is all just for information and curiosities sake. I don't think I'd go with a small block for my '68 Dart although if I do, it would probably be a lower compression 408 (around 9:1), maybe with some boost, for driveablility. There are a few people telling me I should keep the 273 in my Dart, but I'm not necessarily a fan. I've got an engine idea for my '68 Dart. It's a bit unorthodox but may fair out well. It's going to be a lot of work (almost Hemi swap work) but it should do well. And it's still a Chrysler/Dodge/Mopar engine so it shouldn't anger the forum peoples. I'm just going to keep it hush-hush for now. ;)

I kind of want to do a 273 build for an early-A in the future basically taking my entire suspension and drivetrain left over from my Dart build and transferring it over. I'm thinking either a wagon of some sort or a Trans-Am "like" car with a Dart or Barracuda. The wagon would just be a car for sharts and giggles. The Trans-Am "like" car would be a loose representation of what I may think a trans am car would be. Both builds would just be for fun, nothing serious.
