i just got two holley carbs given to me by my grandfather and have no idea what they are CFM wise. the numbers on them are :

d4te-9510ana
list 2156-1
418

c3te-9510-D
list 2156-1
418
2917

You can get a pretty good idea by flipping the carb over and measuring the primary and secondary throttle bores at the bottom of the carb.
Here's a chart showing CFM in the 3rd column, primary throttle bore size in the 8th column and secondary throttle bore size in the 9th column.....

They cross over to Ford part# C9HZ-9510 E this application was used on Ford HD trucks with a 534 engine from 1961-69 some of those old Holleys had a governor they are a 4150 series.

So they are 600 cfm ? how do u know if they have governers? and if they do are they worthless for a hotrod ?

Can you post a picture of them? Actually they can be used with some upgrades they use the same rebuild kits as the 1850-1 Holley as stated above by tech inspector you will have to measure the throttle bores to determine CFM for sure but they probably are 600 CFM.
