I know its a 390cid, 2BBL...
But my truck book got wet when the water heater went Nuclear and every thing ran off the pages...

Heck I was told it was a 360.And I don't know how to tell the difference.

Well just because it CAME with a 390 don't mean it has a 390....

The only way to really tell is to measure the stroke - who knows what someone may have put in there over the years?

360 stroke is 3.5"

390 stroke is 3.78"

The vin says it's a 390

390 stroke is 3.78"

Steve you just lost me.

Cliff the 360/390 are the same block same every thing, only the stroke is different...

 

[Bricks]

Steve you just lost me.

I'm talking about the stroke - the distance the pistons travel from the bottom to the top of the cylinder . The bore diameter of the 360 and the 390 is identical (4.052 standard). The stroke is longer on a 390.

352 cubic inch

# bore and stroke of 4.00X3.50

# engine for the '58 T-bird

# four barrell carb @ 300 hp

# compression ratio 10.2.:1

# cast iron crankshaft

# forged steel rods, mechanical-lifter camshaft w/machined combustion chambers or cast chambers by 1959.

# By 1960, the 352 HP was available with an aluminum intake manifold producing approximately 360 hp.

360 cubic inch

# Used in Ford trucks

# Lower compression engine with heavy duty internal parts

361 cubic inch (1958 - 1959)

# Bore and stroke 4.0469X3.50

# 10.5:1 compression ratio w/303 hp

# In 1959, the 360 cubic inch used cast chambers reducing compression and horsepower.

390 cubic inch (1961-1976)

# Bore and stroke 4.05X3.78

# Three versions available

# 1961-1963: 390 cubic inch with 9.6:1 compression ratio, four barrell carb @300 hp.

How do you measure for the stroke?

 

[Mil1ion]

with a piece of dowel down the spark plug hole

So are you going to do one line post to explain this?

 

[Bricks]

Take a wooden dowel and stick it in the spark plug hole with the piston at the bottom of the stroke, then mark and remove the dowel. Bring the piston to the top of it's stroke, insert the dowel and mark it again. Measure the distance between the marks. That will be the stroke.

That one is going in the books

Thanks Steve

Just be careful and don't break that dowel off inside the hole.

Sorry but I was laying down on the couch leaning over to type on the laptop when I answered.

Steve finished it for me
