If there was one company from the 1960s that made some really awesome and weird intake manifolds it was Man-A-Fre. These guys came up with some nutty ideas and the best part is that people bought them and used ’em. For example, how about this big block Chevy intake manifold that comes with four, count them FOUR restored Rochester 2-Jet carbs! This thing has about 1,000 CFM of carb on top of it and we have no idea how one accurately tuned it as the linkage does not exactly look progressive. If you stood on the gas hard, it seems like you are getting ALL of the fuel and ALL of the air at once.
The neatest thing about this setup is that you just don’t see them anymore. Why? We’re kind of thinking that the dude who bought this thing wanted maximum parking lot impact as opposed to maximum racing performance. Maybe we’re wrong and maybe this thing would make your big block Chevy roar with maximum performance but between all the carbs and the intake design itself, we’re not 100% convinced this is an optimal design.
If we had the bucks we’d score this thing and dyno test it on an engine for fun. We just want to see how weird it is to get right and how much power it would actually cost or make. That would be cool, right?
Make no mistake, we’re not bagging on the thing. It is visually awesome and it would sure stop people in their tracks. Anyone with a hot rod that has an exposed engine would be instant hero for rolling up with this thing adorning the top of their rat like a crown. Are we wrong?
Awesome piece, someone score it.
eBay: This Man A Fire big block Chevy intake comes with four sweet carbs
looks better than the cross flow injection that some one put into production
Judging by the runner length that thing looks like peak power would be just north of 18,000 RPM
A single four barrel would probably outperform it, but you can’t be the coolness factor. A buddy of mine put a 6 pack intake on his 1969 Z/28 back in the day. The factory 780 cfm Holley was quicker but the 6 pack wasn’t too far behind.
They seem to make only Toyota Land Cruiser stuff now.
Here’s a good article if you are isolating today.

I believe John Milner used this setup on his ’32 Ford in American Graffiti.
Looks like a small block manifold to me(
The runners match the intake port locations of a big block Chevy.
