I was curious who runs this type of intake manifold either at the strip or on the street on their 383 (any brand intake, either 180 or 360 design)? Never seen one on a car, although back in the day I was tempted to put one on my parents factory new '71 383 Road Runner.
Yep, I had a stock cast-iron one way back when, but never installed it on my 383. Cool intake & plenty of hood clearance. I often wondered if the carbs were spaced that same as 426 hemi so you could use a hemi air cleaner on an air grabber hood ?????
They are pretty close together but I forget the exact measurement. None of the standard fuel line feeds will work.
Has AFB's 3258 and 3259's which are around 400-500 cfm. But with a 3.91 rear end and a 2500 RPM stall it drinks plenty of gas.
I'v seen one on a road runner I think it was. Back in the 70s early 80s when I used to drive around looking for old mopars hidden on back roads and back yards. The owner swore it was a factory 383 intake and I remember it was cast iron too. I thought it was cool. But the owner wouldn't sell. Cool piece though.
The 2x4 (inline) cast iron intake for the 383 were used for four years. 1959, 1960, 1961, 1962. Part #1859852 casting #1827899. They were rated @343 hp.
The 2x4 (inline) cast iron intake for the RB 413 were used for four years also, '59-'62. Part #1854817 casting #2264877. They were rated @385 hp.
I used the latter on my 440. Carberator linkage had to be modified on the front carb for clearance.
The primaries had to be opened up to accept the 600 Eddies. The ones on right were done in this picture, ones on the left are factory.
