Getting my '80 L82 back on the road, after about a 6 year storage. I'm told I need a new (or rebuilt) carb. I bought a Holley 600CFM (that the Advance website said would work) but the tech tried it and no-go. I'm looking for budget-friendly / utility, rather than performance. Other major concerns - I need it to drop in w/ no modifications, and it has to fit under the stock hood. I'm beginning to think my only option is to have the original re-built. Any suggestions (other after-market options or re-builders) are very greatly appreciated.
