Thanks for the info, and the QF bracket at a reasonable price!

Car is a 4-speed, so no worries there, even if it idles best at 1200. I have a Holley jet kit, so I'll try your recommended setup first.

Can you please tell me what parts I'll need to do the 4-corner-idle conversion? Presumably a new secondary metering block with idle screws, but will I need anything else?

when i'm researching things like this, i usually do a google search then look under the images, found this pretty quickly. it's easy to find what might be good articles or forum posts based on the good pics...

edit: that is talking 3310 there ^ so maybe not everything applies,

here is what is probably another good post.

Just what I need, thanks.
I gave up on this board's search engine many years ago, it's practically worthless.

All that's needed are the mixture screws and gaskets, the correct size tap and a few small drill bits.
It's just a matter of "connecting the dots".

On my old 440 that was actually a 446 as it was .030 over. I ran 906 heads and it had 10.0 comp as it ran good on 92 pump since I used quench pad pistons. I used the MP .557 cam and ran an 850 DP with 1-3/4 headers. It was a street car so I ran the primary power valve. I was running 76's and 82's I believe with a 4.5 power valve. It worked good as I could drive the car on the street all the time and the plugs looked good and even after 2 years on the same plugs they did not foul. Course I only drive maybe a few thousand miles a year. I had it jetted for mph as it did run an 11.49 @ 116 in my 3700 lb 63. I still use the 850 on my 440/493 but I had to jet way up with this stroker as I run 86's and 92's right now to feed this combo and I still run a power valve as its a 3.5 in it now. Ron

The closer the carb is to the motors cfm requirements the closer the stock jetting will be to what it needs. If the carb is to small for the motor it will be rich, to big and it will be lean out of the box.Dave
