Re: 5.0 tuning help needed!
I'd go at least 24lb injectors ,maybe 30's and make sure you get the meter calibrated for the injectors ( very important ) that's about all you need , old 5.0's are simple , you can get it tuned ,but on an old 5.0 it wont be worth the $$$ for a dyno tune ,they might be able to get you 5 - 10hp , you can pretty much get it dialed in pretty good ,with timing and fuel pressure !!! I'd say 38 psi and 14' initial timing
