Put a set of Edelbrock heads on that 400 to jack the compression and breathe like a ****. Who had a 383 Magnum Roadrunner back in the day? No 408 strokher gonna touch it.
Exactly why I'm still considering the 400 stroker (maybe to a 499) with Stealth or Edelbrock RPM heads! I might pop wheelies! But the fit....
The 318 can be stroked to 390 and basically drop right in. A crate 360/408 similarly can fit easily, just need to change the torque converter for externally balanced and slightly modify engine mounts but it cost the most.
