    keep an eye open for excessive blow by, when opening up the stock rings that have already been seated to a larger gap you will encounter more blow bye as the rings will not seal as good as they did from factory. I did this on a 53 im using and i regret doing it

    Search "nook and tranny" on eBay he has the accessorys you will need. I replace the water pump,alt and ps bracket and balancer. These were from a ls3 corvette.

    Thanks for the tips! If I have to pull the motor to make a few changes it won't cost me 10k plus each time, because someone was still learning on my dime.

    fresh set of rings then yea try .027.
    honestly if your using a JY motor then i wouldnt touch it, even rod bolts arent needed in the later yr motors.

    also dont beleive the HR article. I took a JY 4.8 to 26.5 psi and it bent the rods then next pull it exited out side the block. Rod bolts didnt seperate, the rod snapped in half after bending. The load on the street/track vs a engine dyno is totally different. the 48 that exploded was also a weak rod motor. the 05+ motors have the stouter rods[this is true for all of the LS motors. Only motors with stout rods prior to 05 are the Lq9s/Ls2s

    I am going with a big stuff3 LS1 box and stand alone harness. The factory ecu can be used and tuned using HP Tuners software.

    GM performance parts also has stand alone harnesses and ecu package pretty cheap.

    We are still using the truck manifolds. When I said going in for headers I meant turbo system being plumbed. Hope to have some progress pics this week!
