icthyophile;665361; said:Oh, one other thought: One strange thing about the 170 and 200 cubic inch inline-6s used in the early Mustangs is that the cylinder head and intake manifold are cast as a one-piece unit, which limits the hop-up potential of these engines. In other words, you can't just bolt on an aftermarket carb and manifold because the intake manifold is part of the head. Just drive it, love it for what it is, and keep it stock!![]()

I see that Offenhauser sells aftermarket aluminum manifolds, but how would you remove the old manifold if it's cast as a single piece with the head? How would you bolt it on? Perhaps those were made for use with later model heads or replacement heads that were of conventional design, i.e., bolt on intake manifold. I don't know. However, a friend of mine had a 1965 Mustang w/ a 170 that had a one-piece manifold and head. Wikipedia notes that the 144 cubic inch six from the Ford Falcon, upon which the Mustang was based, used a one-piece cylinder head/manifold:unstopable4700;665785; said:aperently someone dosent work on fords. offenhauser sells seperated intakes for two and four barrel. after that headers are easy to find![]()
The 144 in³ (2.4 L) engine was first introduced in the 1960 Ford Falcon. The 144 was made from 1960 through 1964 and averaged 90 hp (67 kW) during the production run. While not known for being powerful or a stout engine, it proved to be economical and could get fairly good gas mileage for the time (up to 25-30mpg). This small six was the basis for all the Ford "Falcon" straight six engines. The intake manifold on this series of engine was cast integrally with the cylinder head (this design was also used by Chevrolet with their third generation inline six); as a result, they could not be easily modified for greater power.
