Negative, the M1 with the popsicle sticks for damms. Not the Holley.
Popsicle sticks on the Offy as well. I can’t visualize witch Offy, because they offered square and Spreadbore versions.
I also don’t remember reading that it was needed for one carb and not the other. Just saying.... perhaps what ever carb was used? I don’t know but assumed a Holley was the carb since that would be the carb to race with unless rules dictated otherwise.
Other than that, how is the TQ experiment working?
