My engine is a 1959 261. It runs okay, especially at idle and when cruising. But step on the gas and it shudders and shakes, then cruises nicely even at 60 mph or faster. I've checked virtually everything it could be and my mechanic who is older than me wondered if the distributor might be the problem. He didn't look at it, I just told him the symptoms. So, I'm thinking if it needs to be replaced, why not go HEI? I did a search and found that a distributor from an early 80s V6 from an S10 would fit. They are available at my flaps, about $200. I could also check out the local wrecking yard. I am open to suggestions. Thanks.
