Hey performance connection!

[mignum]

I got a 331ci aluminum Brodix -11 heads team G intake and super sucker spacer, dome tops ,custom comp cam,3.250 stroke ,6.125 rods , ever since i put that spacer on i almost get run over on the restarts, runs like crazy on top, motor cuts out when i spank it.Took the spacer out and it runs fine wounder why it dont like that spacer?I am putting an old strip dominator intake on now, i am curious if that little of a motor might like a little smaller intake like this.So any thoughts on this DUDE?

Obviously I'm not Perfconn, but your engine doesn't like the bigger plenum that the spacer created. A smaller plenum in the intake will usually give you better low end throttle response at the expense of top rpm HP and vice versa...No secrets there

Just like Sj said to big of a plenum can cause a weak vacuum signal and cause a bog.

A Victor Jr with a 4 hole spacer would wake it up.

[perfconn]

With the right cam and rockers the 2925 intake and the 2 inch supersucker is the best combination but if your cam or carburetor is too big then the engine will like the victor jr 2975 intake and a 4 hole spacer or no spacer at all.

[perfconn]

You didn't by chance put the supersucker on upside down did you? Don't admit it on here if you did,just turn it over.

The holley intake pulled off the corner and restarts alot better but like they said it didnt have the top end it had but it made the car more drivable.I think i will try one of those victor intakes i would like to find a good used one.

Edelbrock makes a 2975 victor jr which is the smallest
They also make a 2976 4+4 which is a little bigger and better
Then they make a victor which is really big
The best one is the 2925 super victor whick is the best design but not the biggest
They also make a 2926 for raised runner heads
Finally they are making a bigger but different design for big inch sbchevys that isn,t available yet.
Don't get the wrong one or performance will suffer.

that little super victor will probly work the best for my little motor,the heads i got have big valves and the intake ports suck so their not flowing very good,prolly why it sucks down low,i have a good set of darts that came from nick b. , but i will have to get a new set of pistons to run them and a set of offset lifters to.

Terry, can you give me a call please.

Have you tried making changes to the acclerator pump cicuit. The bigger plenum requires more fuel at the crack of the throttle to respond. Bigger squirter, more aggresive pump cam, 50cc. just somethings to try and cheaper then another intake, that will most likely hurt the top end.

[mignum]

I have not tried those but terry did mention the bigger squirters to me, just didnt have the time to do it yet, thanks.

[perfconn]

Buddy,
Since you moved the cam,has most of the laziness went away?
Terry

[mignum]

Yes it has, but what was happing here i was getting a bad stumble on the restarts.

[perfconn]

You got it fixed yet?
