502 blower carb base set up
 

hey guys I know this has been gone over before just wondering what a decent base setup is to start with on my engines I did blowers and 1050 dominators. They were 500efi motors that I removed all the efi. New Johnson lifters, Manley pushrods, new springs, locks, and retainers. Scorpion rocker arms. Teague camshafts 240-248 @.50 and .620-.632 B&M 250 blowers and boost referenced 8082 1050 dominator. Fired it up yesterday on the run stand and sounds nasty. Looking for a good proven base line set up on the carb. Right now I’m at 1.5 turns out on the idle air mixture screws and it has 89 main jets all four corners. Any info is good info.

Stock jetting prolly fine but I'd start with 2 sizes larger on all four. Get a wideband o2 regardless even if the engine was dyno tuned. Your idle mixture screws 1 1/2 out is a good starting point but just turn each individually until you get the best idle. Pretty simple.

Btw do a little research with single carb on a 250. Seems like they run a little lean in the front cylinders.

I think your jetting is going to be lean. The stock 1050 carb on a 525SC has #98 jets in all corners and uses a 6.5 PV
