| RE: modified a 390 |

Well you can go here to identify all the parts that you'll need: http://www.428cobrajet.com/id-main.html
But this assumes that your 4.05" bore block can go 80 out to 4.13" which is usually not possible to do and maintain bore integrity. Then you have to get the 428 (or 410) crank and the right CJ rods. Of course, you'll need the CJ heads and intake as well as the CJ exhaust manifolds.
In the end, if you can do all of this, all you'll have is a tarted-up 390. It's a far more doable prospect to modify the 390 to equal or exceed the 428CJ in output without fussing over the displacement. Very easy to to. |
