This is the big toilet, 4.1" rated 1800 cfm!
I think the 511 CID will like it. It really liked the Dominator carb compared to the 950 carb (small venturi).
From Ron's web site:
Quote:
Flying Toilet throttle body is slot-machined to fit a 4500 (Dominator) or 4150 (Holley) flanged manifolds.
3-3/4" 1240 CFM
4" 1435 CFM
4.100" 1800 CFM
The smaller throttle body (3-3/4" - 1240 CFM) is reserved for 327 to 383 cubic inch engines where the owner has no plans of going bigger in cubic inch in the years to come. This throttle body typically is utilized with a "0" pump and .029-.035 nozzle jets.
The middle throttle body which is the most popular by far is the 4" version (1435 CFM). This has a wide span of cubic inch compatability ranging from 355 to as much as 502. This throttle body can work with a "0" or "0-1/2" pump and .032-.037 nozzle jets.
The biggest throttle body comes in at 1800 CFM (4.100") and is set aside for the bigger cubic inch/higher horsepower applications. Engines from 421 to 572 cubic inches can put this throttle body to work. Typically this throttle body will be mated with a "0-1/2" pump that will feed approximately 1000 HP with as big as a .040 nozzle jet.
