I recently swapped my performer RPM intake for a Vic Jr. With the old intake I had ~5" of manifold vacuum. With the Vic Jr. I'm seeing 11" of manifold vacuum. I was running a .5" open spacer on the performer and I'm running a 1" open spacer on the Vic Jr. I guess I was expecting that the signal to the carb would be weaker with the new intake :confused: At any rate, I suppose I'll have to change my f/r power valves. I had 3.5 in there with the old setup, I'll probably go to 6.5 or higher with the new setup. Throttle response seems real good so far. I'll get a chance to test the new setup out next weekend at a bracket race in Alabama.

I will be waiting to see what happens.......Thanks for sharing......

Is the stronger signal because the carburetor is seeing all 8 cylinders with the single plane vs. the dual plane, 4 on this side,4 on that side?

I know the H.P.Books"how to hotrod big block Chevys" has a section about stagger jetting a single plane on a big block.

Ken,

I didn't get a real big difference between the RPM and the vic jr. when I did the swap on my old combination. I didn't even note it. I would think the dual plane would have more vacuum.

Also, how is the weather in Atlanta all year round? What would be a nice suburb to live in? I am looking around for a nicer weather place to be, not serious yet, just curious.

You don't want to be in Atlanta when it snows Tom, those folks don't have a clue,kinda like Dallas and Houston too.

Something was very wrong with your dual plane set up. You will not pick up manifold vacuum going to a single plane. I wouldn't worry about the power valves normally you will need to play with the acc. circuit and the jetting.

Robert,

I'm not sure??? I can't explain it. I would have thought it would have went the other way....

Tom,

Atlanta's not too bad. It's very crowded and the traffic bites, but what big city doesn't have that problem? I live north of the city about 45 minutes in Alpharetta. This seems to be the area where most of the growth is occurring. If I had to drive in the traffic everday I'm not sure what I would do. For example, last week it was raining lightly one morning. I left the house at 7:00AM and arrived at work at 8:10. Guess what? My office is 15 miles from my house :( Luckily I'm able ot telecommute a couple days a week with my work, otherwise....

I can't wait to see how it performs when there's nothing "wrong with it."

Move to Augusta, Ga you will not have that problem graemlins/hurray.gif

OOhh, can't wait to see the results! Hope you get better results! I have a feeling You might pick us some MPH, but it might take some more tuning obviously. How does your car hook right now? what rpm was it going through the traps, and what rpm did it drop to after shifting? Good Luck! Are you going to the track soon?

hey mc71454,why don't y'all come on down to alabama? next week's temps will be in the mid-60's!shoot-dang!i won't hafta wear my shoes!oh heck,we southern boys don't wear 'em anyway! :D

Most folks living here probably can't even remember the last ime it snowed enough to stick in Houston. The last substantial snow I remember was about 1973.
Winter is a great time to be here, it's our summer temperatures you want to avoid. They usually start in late March and end around Halloween.

Tom......Move to Texas......Seems like everyone I know that has ever moved there loves it and is still there.......Plus there are tons of car guy's there...... graemlins/thumbsup.gif

Hey Rod, I was down there 6-7 years ago when they had a pretty good ice storm,in fact it almost went as far south as McAllen. I got into town early to unload at a W.W.Grainger store,and I'm glad I did, it looked like they were playing bumber cars down there. If I ever left Missouri,I'd go to Texas.

wheres the race at ken i hope its warmer next weekend than it was this one.there was a big race this weekend at huntsville unless it go cancelled i havent had a chance to talk to my buddys that went to see if they were racing.i think there is a big bracket race in montgomery after christmas .by the way ive drove a truck alot also and there is no place that ive seen in the south that can handle the snow very well but lucky for most of us it doest last but a day or so and the kids love it when it happens

Try and make it over if you can. What's going on over at Steele? Any races coming up or are they done for the year?

Thanks.

ken still running as long as the weather holds out didnt get to go yesterday worked 12 hrs friday night so i couldnt have seen the tree.wont get to go next weekend for sure its my long weekend to work .i wanted to go to huntsville but couldnt turn down the double time for friday santas coming to town you know and old pop has to take good care of my grand kids .about the victor as for as i know that intake is good from 1500 to 7500 i believe they are the best intake for the strip.the different spacer you used may have made the difference, just a though
