You can remove the number one plug and set the harmonic balancer to Top Dead Center (zero degrees or TDC). Then rotate the harmonic balancer 180 degrees and Then measure the distance the piston moves from when the harmonic balancer is at TDC to a rotation of 180 degrees.
A 352 FE or 360 cid will have a crankshaft stroke of 3.50"
and a 390 FE cid will have a crankshaft stroke of 3.78"
