I went to Griot's today to buy some cleaning supplies, and on the way home stopped by Blood Enterprises to see if they work on Webers. They do, and even have some parts on hand for tuning. Craig Blood did a great job fine tuning my Holleys. They are not perfect, but then they are a racing only carburator, so he did the best he could with what he had to work with.
Well, with all that said, it looks like there is a good possiblity that I will be trading the dual Holleys for Webers this Winter.
And just so you know Jim (Race It), this is all your fault, and my wife will blame you.
