Well first off i have been tossing around the idea of building a Cummins just because it is cheaper to build. Well today my boss told me his uncle was selling his 02 LB7 CCSB for 6K less than the cummins i was looking at. I am in search of 750 to 800hp! Do i need it no. Do i want it WHO DOESN'T. My question to you is. What parts am i missing from this list. All gaskets and seals, main studs, Howard rods, cut and coated pistons, SoCal cam (maybe), arp 625's, MPI twins S366/S480, Guys 75 over injectors, PPE dual CP3's, Fluid dampner, and...... The goal is to have less than 20K into the build and parts. Here is the deal breaker though.... I was wondering if i could take my trans from behind my LLY and but it behind the LB7 if i did some selenoid modifications and put the LB7 trans behind the LLY? I haven't yet bought the truck and if i can't do the trans swap with out costing to much money i am going to buy the cummins. Cummins truck is more money but i can have the same numbers for alot less in a motor. I got a price from II building the motor boring to a 6.1L or 6.2 cant remember for 8K and then the other parts to get there for 10K. Any thoughts?
