How much HP can a 390 make?

1 We begin a 390 FE build with good bones—a solid, mainstream, vintage 390 FE block with 4.050-inch bores enlarged to 4.080 inches with coated Speed Pro forged pistons and Eagle H-beam connecting rods on the 390’s 3.780-inch stroke. This is a blueprint for roughly 500 streetable hp.

Is a Ford 352 block the same as a 390?

The 390 block doesn’t differ much from the 332/352/361 blocks of 1958–1960. The 390 uses the same block as the 360 and 410. All share the same 4.05-inch bore, with displacement varying according to stroke. The only real difference here is the crankshaft.

Is the Ford 390 a good motor?

With a 390, you’re getting a motor with a good head design, a decent compression ratio (varies with type of 390, truck is lower than car), and a bulletproof bottom end.

How do you tell a 390 from a 352?

Now do the same thing on the #4 hole and you should have two lines on your dowel. Measure the distance between the lines and that’s your stroke. 3.50″ is a 352/360 and 3.78″ is a 390.

How do you know if you have a 390?

Take a dowel and measure stroke through a spark plug hole, if its 3.780 it would be 390 stroke, 3.980 would be 428 stroke. Again that just gives you an idea of what it might be as a 410 has the 3.98 stroke with a 390 bore. A 406 has the same stroke as a 390 but a 4.130 bore, the same as a 428.
