Supplier: Man-A-Fre
Install: An evening with a friend

About 7 years ago I installed a Weber 32/36 carburetor on my 1977 FJ40.  The installation only took a few hours and there was a very noticeable improvement over the stock carb.  At that time, it was the only after market item on my Cruiser. I had to install the carb backward to clear the air-rail, (which can now be modified).  The carb worked fine backward.  I only did it without the air rail because, back then, they didn't tell you about it.

The 32/36 progressive is a great carb for low-end power and fuel economy.  They used to offer a 36/36 active, which was a further increase in power over the 32/36 progressive, but that was at a higher RPM.  Both barrels on the active open up at the same time as opposed to the progressive where the 32 opens first, then the 36. They now offer a 38/38 active, I can only speculate that to make good use of this size carb, you'll need a RV Grind cam, a good ignition, and a header.

Remember, bigger isn't always better.  If you want torque, low-end, and fuel economy get the 32/36 progressive.  If you want more mid-range and plan to get more like 190 hp, then go for the 38/38.  Note:  I am not saying the 38 gets you to 190hp, but it will be able to accommodate 190hp.  Look into the head, 3 angle valve job, knock the pockets and port match the intake and exhaust.  The engine is just a pump; the faster you get the air in and out determines how much power you make.  Don't even waste time with the Holley.
