    Cylinder block serial # or block casting# identification

    Anyone know how to identify which block (i.e. LB7, LLY, LBZ, etc.) from the serial # stamped on the block or the casting# stamped on the block. I acquired a couple of bare blocks and don't have a VIN to track the engine model that way.

    Alternator takes a long time to start charging

    I changed the alternator yesterday as I had a spare one and the truck started this morning after sitting for 12 hours no problem and the alternator began charging almost immediately so maybe it was an alternator problem. Thanks for the replies anyway.

    Alternator takes a long time to start charging

    Recently, my 2007 GMC 2500 HD Duramax will run the batteries dead overnight. After boosting and starting, the alternator takes up to 5 minutes or more to start charging. The volt gauge will start to move then return to zero. It will do this for a few minutes then suddendly it will jump to full...

    Use Torque Plate or Not

    Torqueplate Thanks for posting the video. Irrefutable proof that torque plates are necessary when boring/honing a engine.

    Use Torque Plate or Not

    I hope some engine build/rebuild shops chime in on this subject. I know in some applications (NASCAR engines, for example) that not only is the boring/honing performed with torque plates, but all accessories and brackets are bolted to the block and coolant at raceday engine operating temperature...

    Use Torque Plate or Not

    Torque Plate Thanks for your input Iowa LLY. I would be interested to know if anyone has performed before and after bore dimension checks, that is, bore and hone with torque plates and check bores in several places, then unbolt the plates and check the bore in the same locations to determine...

    Use Torque Plate or Not

    Torque Plate Ya. I knew what the answers would be. Also, I know better. Got talked out of using a torque plate but looking back I should have insisted. Maybe time to look at a different engine builder.

    Use Torque Plate or Not

    I'm getting conflicting responses from local engine builders as to the need to use a torque plate when boring/honing a Duramax engine. The argument I'm getting against, is that the block is so beefy and rigid that block distortion from bolting/torqueing on the heads is very minimal or...

    Hydroboost unit noisy at highway speeds

    Found the problem! As it turns out, it was neither the pump or the hydroboost unit, but rather the 3" DS IC pipe coming up against the hydroboost unit in boosted conditions. Sounds just like the growl you hear when the ABS system is doing it's thing on slippery roads, only continuosly when at...

    Hydroboost unit noisy at highway speeds

    Just got the truck back running mid August. On the dragstrip and on the highway, any speed over ~ 120 kph (75 mph) and up causes the hydroboost unit to growl (same growl as when the ABS system activates in slippery conditions) continuosly. If I slow down to ~ 110 kph (70 mph) the noise will go...

    No flow to cooler

    2003 LB7/Allison 5spd. The truck sat for 10 months over winter(inside heated shop) and while head work was being done. Engine and trans remained in truck. Nothing was touched on the trans,trans cooler lines, radiator or trans cooler. When engine work was completed, fired it up and went for a...

    Who has a 5 star converter and likes it? And billet flex plate. use it or no?

    I have 5 Stars in both my daily driver and my race truck. The one in my daily driver acts as though it's slightly out of balance and causes the truck to shake a little, especially stopped while in gear. Don't notice any vibration at highway speeds. The one in the race truck idles smooth however...
