Agree with others, if it’s not broken, don’t fix it.
About 10 years ago, I decided my 30+ year old Edelbrock Performer carb on my V6 was getting long in the tooth so should be updated. The old one was still running great, so no idea why I got this wild hair. I bought a new Performer carb, matched the tuning from the old carb and slipped it on. It never performed the same, so I bought a Holley 390…same result. Tried a FiTech fuel injection…a miserable failure.
The old carb went back on the motor and is still running great. It sucks that I have over $2,000 invested in trying to fix a carb that was never broken.
