HEI... 50k V vs 65k V...?'s

[hcaz095]

So, after going to ebay and looking at HEI's available.. I am not sure if I should go with the 65,000V or the 50,000V? My truck just acred the points, so I will be replacing asap. it is a 1972 c10 lwb......350 w/ th400 3.08 gears stock original motor... I will be doing some pulling of boats and motorcycles if it makes a difference, but otherwise i drive fairly slow. Give input wither way... Is there a plug gap difference? Anything I should know.....

Thanks,
