Okthe speedo page has a lot of info! Thanks Denny. As for the weight of the finished truck whatever the stock weight of the 48 ford was, minus the original weight of the stock 6 cylinder was, plus the weight of a 71 lincoln 429/460-still don't know, a c-6 tranny, minus whatever stock tranny was in there should be close to the finished weight of the truck!
The tires are lt235/75 R15, on 15 inch aluminium slot mags from the Dukes of Hazzard years!
If I chose to go with an electronic speedo, is it easier to figure the speedo thing out?
