Working on installing a Holley 600 on my 250 6 cylinder. Doing a conversion of the carb per Tom at 12bolt.com instructions. It converts it to a 3 barrel; 1 primary and 2 secondaries. I just got a call that the Clifford intake has been blasted and ready to pick up. Now to get the carb back together. Then the fun of figuring out all that need to come together to get it on the truck and working. I'm keeping track the process on my blog; https://myol66.wordpress.com/.
