Unfortunately 73 up b bodies do have different k frame for big and small block engines. But I think Schumacher makes conversion mounts.
What year engine? What small block currently? There may be balance problems without the correct flywheel.
You'll need new head pipes wether you use headers or manifolds.
I'd run the existing radiator, if it turns out inadequate it's easy to change later.
Power steering brackets may need to change

I just checked, have the huge cutout with mat cover. That right there is half the battle! I restored a 318 '74 Charger twelve years ago and sold it to a guy that put a 440 in it. I recently bought it back from him and I'm doing a few things to it to give it a more original appearance. He DID change the crossmember for BB application, but didn't do anything with the passenger side fender. I now have to remove the motor to properly cut out the inner fender and add that large mat. I'm so not looking forward to that...

thanks everyone. someone told me my VIN numbers says it's a factory 400 4spd car. I bought a 68 440 with 915 heads? so i'm a body guy not mechanic. I did rebuild the clutch two winters ago. the story is the guy I bought car off of put a small block in to give his dad a last ride before he passed away. when I changed the clutch I had to pull a torsion bar to make room. looks like the motor was to close to firewall or i'm just special. in the trunk it had motor mounts and another bell housing. Your VIN will confirm that it's a 400, but it won't tell you the trans. You'll need a fender tag or broadcast sheet for that.

Other than Schumacher as mentioned, Brewers Performance is your Mopar source for 4 speed parts and knowledge. They've been doing this a long, long time.
Iām listening.
