307 Regal said:
alright well I can't find it but I'm nearly positive it had no vacuum line. If your car is running fine on the ECM at the moment then it might be a good idea to leave it as-is for a while. If you decide for sure to go that route then keep in mind you could need a vacuum advance carburetor as well. The completely vacuum operated setup worked out pretty good for me but keep in mind you're still putting money into a vin "Y" 307. The money you might spend on the 307 could instead be money saved for an engine swap. Your call.
@307regal are you running Vin 9 or Vin Y? which exact distributor and carb are you running? the reason that sparked all of this is that my engine is running rich as hell right now...that gassy smell when running ..and when i turn the engine off it just smells up my garage and it gets rises through the ceiling/floors upstairs. this started last week but before then i knew it was running rich.
i was planning on going with a vac advanced distro and replacing the carb with a 70-72 qjet from Guarenteed Carbs..but i've been thinking about going with a holley. After that i'll ride this for a year or two while i stack for a chevy with a 350 already in it..but the 307 only has 37,800 miles on it so it's almost new to be honest. it just sat for a few years after my granny passed. She put 30K miles on it in 13 years. if i can get a set of 5a heads for the low i'll put those on and change the intake to a edelbrock. i already have a TH350 transmission being rebuilt now so i'm trying to keep this freshen up lite on my pockets. but i wanna do the distro and carb like in a week or two if anyone has any part #s or other info..i appreciate everyone's feedback on this...
