I can’t remember off hand if the popsicle sticks were for Holley carbs on the intake or for the TQ.
The Offy intake can be had in ether square or spreadbore and the MP books illustration is of a spreadbore Offy. I’ll have to look later.
Still, locomo has a good point that ether extensive dyno or track testing is needed to find the maximum ability of the parts used.
