The Weiand Company was founded by Phil Weiand as a performance parts warehouse in the 1930s and sold a variety of speed parts. The first Weiand product, the "High Weiand" manifold was manufactured and marketed in 1937. It was the first aluminum intake on the market. In 1949 Weiand introduced a series of "tri-power" and four 2-barrel manifolds and immediately after WWII Weiand debuted a line of aluminum cylinder heads for flathead Ford engines. The famous "Drag Star" line of "log" manifolds for Hemi engines was introduced in 1952 and in 1957 Weiand developed complete blower drives for the GMC 6-71 supercharger. The first dual plane, 180º intake came from Weiand in 1965, known as the "Colt" and in 1968 Weiand introduced the "Hi-Ram Manifold" and its patented D-port technology. The popular "X-terminator" single plane manifold series was launched in 1972 and high performance aluminum water pumps were made by Weiand the following year. "X-CELerator", a series of performance single plane intakes was developed in 1974. The first models of the famous "Team G" series of 360º racing manifolds were introduced in 1978. A year later Weiand's "Action" series of high performance replacement manifolds debuted. Weiand became the first OE supplier of superchargers to Mercury Performance Marine in 1990, and over the next three years the "Stealth" series of high performance dual plane manifolds was designed, the "Pro-Street" supercharger was certified "emissions legal" by CARB and Weiand received the industry's first "E. O. " for an intake manifold. To make more power you have to get more air into your engine. Look to Weiand as your power source!

The manifold fit great in my 1976 with a 400 motor in it, had to remove the locating pins on both heads with a set of pliers, i decided to save them for later, dont listen to the “doesnt fit because its made in china” crowd, it fits if you’re smart about it! Im a Porsche technician and if you have problems fitting it, you might need to leave it to someone with experience. Got new gaskets, valley pan and bolts, used the old bolts as locating pins to keep everything in place! Truck runs fantastic!

Bolted down to 1977 400ci. I had to grind out a spot in the right front corner and left rear corner to accept that I don't want to remove the small studs in the heads that hold the intake valley pan in place. Had to replace the intake gasket in less than a week due to the rubber end pieces shattering, just use a respectable silicone bead don't and back, not the rubber gaskets. Works great now that it's all fitted.

Don't do it! Holley shipped weiand to China and the quality reflects. It wouldn't even fit my motor due to there being no locating dowel holes in the intake. Go with edelbrock. Made 100% in the USA.
