(Todd, I read somewhere that the new Edelbrock 94's are supposed to correct the bleed down problem. Not to sure about that plus the gas boiling after shutting off the engine is another problem. My bird has no room left for a phenolic spacer to insulate the carbs unless I want to cut holes in the hood. I used chrome stainless steel lines from Vintage Speed with absolutely no leakage. I had to modify the lines that Charlie sent me to clear the linkage so I feel comfortable bending up new ones. It wasn't as hard as I expected. I am using the stock tach drive 57 distributor with Petronix and MSD 6 but it needs to be gone through. At this point I have the vacuum advance plugged and bumped up the initial enough that the mechanical advance gets me to the right total advance. Still need to work on that. Thought about coming to some of the events over your way but not ready to push the Bird over Hecker and Pacheco Pass yet. It is a fairly strenuous drive from Santa Cruz.)



OK, my bird's gas line filter always seem to bubble or percolate after I drive a bit. I've always taking it as normal? Is it a problem, carb leaking down or venting issue. The filter is the original style glass AC unit, so it's easy to see. Something I need to fix?

The basic problem is the fuel blend.  Virtually all pump gas now days is formulated for closed system EFI.  There is little or no consideration given to "vintage" (pre-2000) engines.  About all you can do is look for 100% gasoline (non ethanol) and insulate your fuel lines as best you can.  You could also experiment with shielding the carburetors from the intake and blocking off the heat riser passage.  I have used a sheet metal spacer between the carb and manifold that extended under the float bowls to deflect heat off of the manifold itself (on my single 4 bbl intake).  It also may act as a heat sink to conduct some heat away from the carb base.  Unfortunately, those early birds were notorious for high under hood temperatures too which only exacerbates the problem.
