Is a 427 and a 454 just a 400 core stroked with different length rods & or crank?

 

Theres a 427 big block (the true 427 designate) and a 427 small block (427 stroker motor).

The big block is a 4.25" bore x 3.76" stroke.

The small block is a 4.125" bore x 4.00" stroke.

 

doubt if it's really part of your question but ford also has a 427. chevy has two 427s, tall deck truck engines that are basically junk for preformance applications and the standard deck car engine.

 

Typical big block:



Typical small block:

 

Oh contrare... the tall deck truck engine is the block to have in order to build a 510.

 

Ford's 427 is not really a 427 though. Its a 425. And their 428, which actually is a 427, is the same bore/stroke as a 427 stroker small block chevy.

The tall deck big blocks (427s anyway) are good for racing use, but too expensive to build for the street, compared to a regular big block.

 

Don't forget the 429 Boss Ford, and the 427 SOHC Ford.

 

The 'Cammer' 427 was cool, untill NASCAR banned it, along with the Hemi in about '65 or so. The Hemi came back almost overnight, but the Cammer was out forever.

The Boss 429 is a Hemi

 

Yes, as I recall Ford refferred to it a a semi-hemi.
