Tony,
That's not a 390 at all it comes out to a 396.1 And 6.4L
What did you do to get "390"?
IF you use the actual bore of: 3.90625 add .030 to it for the overbore size, with a 4 inch stroke, and times by 8, it comes out to: 389.4, and then you can round it up to 390....
But the numbers you gave for the bore WITHOUT the overbore doesn't come out right! I take it this is a LA 318 then?
For the Dyno numbers that sure is impressive to know of a 318 with that sort of power, who'da thunk it?
