396, 427 & 454??
 
Im trying to find some info on the net about the diferances between the 396, 427 & 454? Can a 427 become & 454 and a 396 a 427?

What can be done to a 396?

Bore & Stroke.
How much $$$ do you have? https://www.yenko.net/ubbthreads/imag...ns/naughty.gif

A 396 and a 427 have the same stroke and can use the same crank. A 427 and a 454 both have the same bore and can use the same block. If using a 454 crank in a 427 block the block needs to be notched a little so the crank will clear. 396s and 427 are internally balanced engines and the 454 is externally balanced. The flywheel and harmonic balancer off the 396 and 427 cannot be used on the 454 and the 454 ones cannot be used on the 396 and 427. If this info is not correct, someone please correct it.

512 blocks had the relief for the 454 cranks cast in, and were used on both 427 in 69 and 454 in 70.

JFK pretty much hit the nail on the head. You can, however, set up a 454 to be internally balanced, but it's kinda involvled...

Thanks

I do know someone who bored a 1969 model 396(325 horse) out to make a 427, and he was successful, I even got a ride. But my understanding is that it is somewhat risky, sometimes it does not work, so I wouldn't try it with a block that was important to me.

Excuse my ignorance but how do I update my profile?
