Indy LA-X vs. Eddy heads
I don't understand. Heres some facts of how displacement works;
4.00 X 3.58 = 360
4.030 X 3.58 = 365
4.060 X 3.58 = 370
Now with a stroker crank @ 4.00 in the same bores
4.00 X 4.00 = 402
4.00 X 4.030= 4.08
4.00 X 4.060 = 4.14
In a 340 engine
4.040 X 3.313 = 339.8 AKA 340
4.070 X 3.313 = 344
4.100 X 3.313 = 4.449
Now with a 4 inch stroker crank installed;
4.040 X 4.00 = 4.10
4.07 X 4.00 = 4.16
4.100 X 4.00= 425.5
Did that help?
