I am 3rd owner of the truck and the previus owner only put 28k miles on it in 6 years. I have put 2700 miles on it in 6 months. Mostly hwy road trips.. I am not looking to build a street strip truck. Just want plenty of tq to pull the race car or make the truck scoot when I want.
I just hate to get it all ready for H/C/I swap, then tear my 350 top end off to find worn cylinders or something.. I know many of people who do H/C/I on motors with over 130k miles. Mostly cars like Mustangs or Camaros, sure they get beat on more then my truck. My truck is also heavier..
Other weird issue is the engine temp never gets above 140 degrees. It takes hours of running to get it that warm. I have replaced so much stuff on this engine to work out the bugs, at one point i was just fed up with the 350 so I started building the BB. I can always save the BB for my race car project..
