| In 1969 it was renamed the 390IP. |
| By Dave Shoe - 06/01/2001 1:15:10 AM; IP 216.243.158.57 |
Ford muckety-mucks decreed that for 1969, all 390s would lose Thermactor, thus forcing only mild cams in that displacement. Thermactor was expensive and added no selling value to the car, so it was decreed in writing that only the 427 and 428 displacement FEs would be sufficiently profitable to have Thermactor for 1969. The emissions-laden 427 was layed to rest by the newly hatched 428SCJ brainstorm after 1969 cars were rolling and before any 1969 427s were built.
The 390IP is the same as a 1968 390-4V station wagon motor, except it got the more restrictive "unibody" exhaust manifold which held all Fairlane/Mustang 390s back, and it also got a neat looking free-breathing air cleaner and a 600 CFM Autolite carb instead of the 470ish CFM Autolite on the 4-barrel wagons. It also got 4-barrel compressioned pistons (10.5:1).
The basic 390IP is very sturdy, as are all 1964-71 390s. It only needs a cam and valve springs, and a (compatible!) header or CJ exhaust to wake up. On the intake side, adding a CJ (iron), 428PI (alum), Ed 427, or Ed RPM intake would take it to the realm of being a street terror.
Hookers don't work with this head. Only some FPA headers port match properly. Anyhow, you may not be interested in making it look non-stock, so CJ exhaust manifolds (orig or repro) would be VERY WISE. Save the tiny 390 "unibody" exh manifolds for "originality" purposes only.
