I have a modified Holley 600 CFM with non-adjustable floats. The guy who built it installed a vent-tube like the Truck Avenger, and pretty much built it for my vehicle. (Built 302, c4, 35's, 3.50 gearing, lifted, locked, mostly a daily driver at sea-level with occasional off-road trips from San Diego to maybe as high as Big Bear).
I was up at about 2,500 feet on a trip, and started heading up a nice incline which took me to around 3,500 feet in what seemed like a mile. Any time I hit any steeper sections in the road, or let my foot off the gas the engine wanted to/did die. I ended up turning around and could tell things got significantly better as I headed back down the 1,000 foot incline and played around at the lower altitude.
Apart from this trip, when just driving around at sea-level on the street, if I slow down suddenly and take a sharp turn my engine sometimes stumbles/wants to die if I don't get back on the gas right away.
The question is, do I need to re-jet before I go on these trips or during? Do I just carry a jet-kit and increase my jet size for every 3,000 feet when heading up a mountain or is the altitude range broader than that? What's the quickest way to do this on a trip? Also, can anyone reccomend a good book or website for understanding Holley carbs?
