They are all the same '66-'72 except Toronados. The only difference is divorced choke or hot air choke. The aluminum W30 intake has exactly the same internal dimensions.
At 62 pounds if you fly with the cast iron version it exceeds the weight limit and there are extra charges (a friend gave me a '72 version on a visit).

Among the non-Toro BB intakes:
A - 2-bbl 1965
B - square bore pre-QJet
D - 66-67 2-bbl
E - 66-67 4-bbl. One coolant switch hole, Div. Ch.
F - 66 3x2 [similar '65 and '67 more rare versions also]
J - '69 H/O only
J - '68-9 all other RWD BB apps, Div. Ch., TWO coolant switch holes
2-3 variations of the aluminum 70-72 W30 intake, often no letter ID
L - 70/71 2-bbl
P - 71 2bbl
R - 70/72 4-bbl
U - 72 4-bbl
Then after 1972 is the ubiquitous "W" casting with EGR, and some more rare X & Y castings.
Then they had to stop making BB's because they were out of letters.
A number of significant differences, functionally.
And, I will take a J-405233 at the price of a J-398662 if they are all the same....

The 70 iron intakes that bring any money are the four speed ones. I have no idea what makes them different but I sold this one for $100 ten years ago. I don't even remember the casting number

Cast iron intake
Yes I know there are many small differences in codes, choke styles and casting numbers. One previous post asked if the 88, 98 intake was the same. I was only referring to how much power they made. I believe there is no significant difference in power output between factory 4bbl intakes. Has anyone ever swapped a Toro intake for a regular intake and then a W30 intake?
