Hi folks - First time here. I have been pondering this question for a while and thought I would put it out to see what the general consensus would be. First a little about the car.
'70 SS LS5 - Original 70 date code CE block - Stock. Was my first car which was purchased in 1990 and did a frame on resto with my Dad (he is a "Factory Orig" guy so that's how it was restored). Since then I have put a few thousand miles on it (maybe 80k miles on it now). Over the years I have rebuilt the original Rochester several times and had a few Holley's on it. All work well for a few years then act up. With today's fuel and the fact it gets driven 100 miles a year they last even less. I want to keep it stock but wouldn't mind adding a little performance boost while I'm investing the time and money. Looking at the "bang for the buck" factor as well. So I have a few options:

1. Rebuild the Rochester again
2. Replace with a different, maybe more tolerant carb (if that exists)
3. Convert to an EFI system - I have seen some good posts here regarding
4. Sell it - The lack of use doesn't do it much good

I like the EFI thought but the $3k price tag is hard to swallow. If I went this route I would probably go all in and pull the motor as it has never been out of the car and do the heads so I can get away from lead, ect. So that would really put me in the $5k range...even tougher to swallow


Thoughts??

You will have better luck with the carbs if you put Sta-bil Marine Green in the gas to prevent separation. Works real well. Drive it more will improve the odds also.

Stick with the carb. You can rebuild a Holley in less than an hour with a good clean up. Every few years is not a big deal.

We have a 2005 Corvette and I don't think I would want it sitting around with old gas in it for long periods. As mentioned above. A carb is a quick, easy rebuild, especially a Holley, compared to the FI. I've always had good luck with Sta bil in our cars when stored for the winter and have never had a gum up problem. Buying premium gas from high volume name brand gas stations can't hurt either. This new stuff sure is nice when working, but when it doesn't, there are going to be a lot of dollars going out. I hold my breath thinking about it.

Thanks for the reply's. What model Holley would you run? It seems to be difficult to find a 750cfm spreadbore out there. Never had much luck with the adapters. As far as additives I've used them all. A station near me has leaded race fuel, 104, no ethanol at the pump that I started using at $9/gallon. Seems to be better but still has the problems after a while
