Which one Bibbs? They made 390's from 1961 on and in several configurations. 4 barrels ranged from 300 to 360 HP depending on the year and usage. 3x2's were from 340 to 375 depending on the usage. These are FoMoCo gross ratings.  ------------------

I knew that. Really I did! This 390 happens to be in a Galaxie 500. Not exactly sure the year. It is a big 4 door car. Round rear tail lights. This probably isn't helping is it? It currently has a 4 barrel on it.

Well, since 1964 is the last year for round tail lights I will hypothosize that it is a 62-64 car. If it has an Autolite carb and an iron intake manifold then it is probably a T-Bird 300 HP 390. Realistic HP is around 240. If it has a Holley and an aluminum intake it could be a 390 340 HP PI engine. ------------------

It does have a Holley and aluminum intake. If it were you, would you go to a Jasper Hi-Po engine that starts at about 325HP?

No way! If it is indeed a "P" code 390 PI it has solid lifters, adjustable 1.76 rocker arms, a good crank and rods, very good exhaust manifolds, and a great intake. A very good if not the best basis for a nice FE motor build up. It is about 320 HP realisticly. ------------------

On the solid lifter 390 hipo in 1961, Ford "published" (for what that's worth) 375 h.p. for the single 4-V, and boasted 401 h.p. if you added the dealer installed tri-power. One hell of a suprising running motor. I own one.

A few years ago a friend at work brought in an old car mag from 1961 where they tested and tuned on a 1961 401hp galaxy. The article even had sketches on how they made the headers for the car! Other than the headers, the motor was untouched internally. They got the car down to 13.30's! I don't know how legit there timers were back then, but I was impressed! I made a copy of the article, but I can't find it right now.

I didn't even bring up the 375 or 401 HP engines since they are so rare and the likelyhood of the 4 door having one was zero.  Ford built 4 different versions of solid lifter 4 barrel 390's. A 330 and 340 HP Police INterceptor (PI), a 360 HP Nascar package and the 375 HP high compression version. ------------------

So what did my '67 S-code have stock?
It's now rebuilt with lots of aluminum up top.

Depends on which FoMoCo specs you believe. Early ones said 320 HP and late ones said 335.  I have both in print and one in an original 68 owners manual I have. ------------------
