Hey guys. My engine specs are in my sig. I haven't fired the motor yet I'm just trying to get some things ready for when I do. I know that its not possible to really dial in the carb without running it but was just wondering if I could get a could starting point from expeeiences. Carb is a holley 850dp has down leg boosters and screw in air bleeds so I can easily change those as well. I'm also trying to recurve the dist. Its a stock gm with accel coil all new cap and rotors any advice on which springs and weights. Adj vac adv? Thanks guys.

For the carb, put it back to Holley spec. Jets, power valves, etc. if the carb is correct for the application (sounds like it is) then it should only take a slight variance from box-stock to work well. For the dizzy, again I would start with stock components to get it running. Once running you can dial in a better advance curve once you can put a timing light on it.
