Carb spacer question
Here is my new motor in my 73 vette. 388 stroker. Has Victor Jr. 1-inch tall intake, and 1-inch 4-hole spacer. Comp cam xs290

Any recommendations whether to keep, change or eliminate the spacer?

You think that is true even at a 2inch overall height? Or if so, should I try 2 inch open, rather than 4 hole?
GordonM: I havent run it yet, as I just passed the 500 mile break in. Tried it on the street though last week
I will go to ATCO at the least for the 1975 and older shootout. You?

I have run many times at Atco. It is only about 20 minutes for me to go. I'll sometimes go on a Thursday night for the street muffled cars. If you get there when the gates open you can get in 4 or 5 runs before the crowd gets there. When is the 75 and older shootout?

Do you know if simply a larger shooter would work, or wou ld I have to put in a larger pump? I have a Holley HP with standard 35 shooters on primary and secondary

That is the one that where the holes widen at the bottom?

Vetdrms also used that spacer and had good success with it.. I believe that he used the 2 inch version..

Add the spacer and see if it gives you any trouble. The pump circuit is probably a little rich anyway so adding the spacer may make it just right. My earlier post was simply to warn you of a problem. If you install the spacer and get a stumble out of the motor this is the fix.
By the way, a larger shooter won't increase fuel volume. It simply delivers what fuel volume there is faster.
