Thanks, Jim I don't see any connection between dual carbs and dual valve springs, unless they are assuming that you are going to rev your motor up higher because of the dual carbs, which is nonsense. Find out what the rates on the springs are. If the dual springs are rated higher, consider passing on them, because they will just cause more wear on your cam and valve train. It is a stock motor, after all. As long as we're talking about it, why go with dual carbs? Having dealt with them for the last 7 years on my bus, I would never choose any dual carb setup over a single carb because of the synchronization problems. This assuming you can get equal mileage and power out of a single carb, which I'm sure is at least close to the truth. -David ============================================================================= David Schwarze '73 VW Safare Custom Camper (Da Boat) SAIC Comsystems '73 Capri GT 2800 (Da Beast) San Diego, California '87 Mustang Lx 5.0 (Da Bruiser?
