So... it seems that 75k miles and just over 3 years was the magic recipe for bottom end failure at that 700hp mark... Compression test shows cylinder 5 at 250psi and #4 at 300psi... all others 350+. I have not torn it apart yet but should know more by the weekend. The engine is ready to come out, just need another hand to help remove it from the truck.
Truck was definitely not babied, regularly towed 12k and would frequently see over 50psi of boost. I am definitely bummed out but cant complain to much I think it had a good run.
Thinking of buying a set of LML rods to replace the shortened ones. I dont plan to add any power as it currently has plenty for what I need it for. Just wondering if the LML rods will hold up better? Also does anyone know the weight difference between the older rods and the LML? Will the crank balance with them? I'd like to get this thing back up and running ASAP and not throw my entire bank account at it....:roflmao:
yes it will balance. I would look more for LBZ/LMM to support the wrist pin more. Not that LML's wont work but i have not really seen them show to be much better than LBZ/LMM.
id look at this two ways if you want to do this cheap and dirty.
Either pull just the rods, throw the new ones in and stab it all back together with a new set of rod bearings and call it done (maybe rings if you want to splurge)
OR
Tear the engine down, have the pistons delipped, balance the rotating assembly and have the crank/cam keyed, new bearings, hone job on the cylinders, new rings, new main bolts, probably some other stuff im not thinking of off the top of my head and stuff it all back together with the reg stuff. at that point, you are just missing rods for a short block that would hold 800hp without much issue.
