Rochester 2bbl help

[QUOTE=Stan Weiss;715381]Are you sure it was 56? Olds did have a tri power "J2" engine in 57.

Not sure, I went by the ad at swap meet and bought just the 1 with choke. An old old racer suggested they were better. I think it flowed 525 cfm and the best Rochester someone in our group was at 500 cfm.
The others were under 500.

Tim, You want to be careful, going to Indy with that combo.
There's a fella out there that seems to think that some boosters are more okay than others on a 2 GC. He's not hard to find. In fact , he just might find you!
