Should I go with the divided type like this or the open one....Shawn seems to think the open one could cause swirling???

I found the same info online but it was in so many words and not directly stated so I am interested in Ron's thoughts on that as well. popcrn

Open is fine.....i've run 1in open spacers on dual plane intake manifolds in the past with zero problems related to fuel distribution.  Wink

Most "performance" dual planes (RPM/CH4B) will have the divider partially milled down. This actually helps with fuel distribution and allows both banks of the engine to use all 4 venturies of the carb. The base insulating gasket will accomplish the same thing as an open spacer but to a lesser degree because it is thinner.  yesnod

The only application i can see using that divided spacer would be on a stock manifold which is something I would never use  Tongue

Yep certainly a good question  2thumbs

When you pull the carb have a look  scope at the divider in your manifold and you'll see why the divided spacer/gasket will have no effect on fuel distribution.  Wink

The designer(s) of those performance dual planes did that for a reason.  yesnod

Thanks for that Ron!   cheers  Since I have a stock manifold that would work for me then.

Well I ordered the gasket yesterday from Summit Racing and got a notification it was in at my U.S. postal outlet so we went over and picked it up this afternoon  yesnod Also hit Autozone and after 5 minutes of going through air filters with my old one in hand I found a STP one that was same diameter but not as tall( a little over a 1/4"). So I am hoping that the extra height that adding the gasket will cause, the reduction in filter height will allow me to use my Mopar Performance Air Cleaner still. I don't have a lot of clearance nowto my hood and needed a base off of a coronet that Shawn had when he was building my car up. One reason I love living near the border is my quick access to parts  2thumbs

Make sure you check your AIR CLEANER STUD height before you drop your hood.. We dented a hood from the inside once that way.. Rotten lesson at best....  brickwall

Got the new Firecore Distributor & coil in with a ton of help from firefighter RON!!!! Didn't put the carb spacer in as I need to put in a new fuel line(it would be too short) but man does the car run nice now! Had a float stick in the carb while testing yesterday and we killed the battery trying to start it. Luckily we were a mile from my place and the wife came to the rescue and we boosting it. I put the trickle charger on it after we got it home till I went to bed. The motor only has 162 miles on it and has sat a lot over the winter and spring. Hopefully get out tonight and run her again! Here's a video of the idle  2thumbs

 scratchchin  I need to maintain carb functionality so I don't want to block my heat crossover.   Can a hole be drilled in the pan gasket to let "some" heat in so the choke operates but not so much that it boils the fuel?  Will it eventually just heat it up anyway causing locking issues?   About the only option i have because carb spacers screw up the choke linkage for me.   shruggy

Car is running great now!!!!

Here are my temps I took after a 30 minute drive

1) cylinder head surface temp : 228*F
(2) Intake manifold surface temp : 126*F
(3) Carb main body surface temp : 111* F
(4) Valley pan surface temp : 156* F

Mind you we live very close to Lake Huron and it was only 60* out last night around 6-7pm

 cheers

 2thumbs  Great to hear!

I am going to force myself to go through the same over the next week. Going to take the carb with me over my vacation week and rebuild it and then do the valley pan/ spacer upgrade.

A tad late on a response but none the less. Several folks have drilled a hole in the crossover to allow some heat flow. I have heard folks say they have drilled a 1/8" to 3/8" hole.  If you have a stock thermal choke you should just be able to add the spacer and simply bend the arm on the choke to make it the correct height/length.

I drilled 1/8 holes to let some heat in. I found if you do that it just lets the heat burn the valley pan heat blocks away. DO NOT DO IT!

For what it's worth, I installed a 1/2 inch phenolic, open spacer and not only has it seemingly eliminated any hot fuel issues, but I felt the car picked up a little muscle in the mid to top end.  I do feel like I lost some low-end though; the off-idle bog I've had since the beginning has gotten worse.  All in all, I agree that a spacer of some sort will help most of us...

Will a half inch spacer clear the hood on a big block with an m1 intake On a 68?
