just picked up a 92 LX 5.0 that someone has hacked up and made it carb'd. its got a holley 650 dp from what im told. I dont know the first thing about carb's other than they dump fuel into the intake

now that being said. the car runs rich and kinda stumbles on its face some times. anyone wanna tune the carb for me to get this thing running better?
i took it to lakeland drag strip last night and ran consistant 8.6 @ 88mph with a 2.1 60ft, with a best of 8.5 @ 88mph with a 2.0 60ft. car kept loading up on fuel and stumbling on the launch...

i dont mind paying a few bucks or buying some beer if someone can help me out, i dont know anyone local that messes with carb's. I live in Lakeland btw

thanks in advance for any help
