Does this have the 351 mod? I have a 78 F-250 that drove me up the wall when I was fixin it up cause everytime I would drive it it would run great for 10-20 mins then die. I thought it was the coil and it ended up being the Dist. I replaced everything up to the dist then finally the dist and the problem went away. Best part was it was like 46 bucks for the dist.
