| RE: What do I have 390 or 428? |

| One indication of what you have is the engine stroke. You can measure that by placing cylinder 1 at TDC and remove the spark plugs for cylinder 1 and 4. Measure the distance from the edge of the valve colver to the piston for those two cylinders. The difference between these two measurements is the stroke. This is hard to do accurately, but give it your best shot. 3.5 inch = 352 crank, 3.75 = 390 and 4.0 (3.98) = 428. |
