why teeeeeeeeeeease????
Any mods to the new motor? Or just need it to run, looks like a pretty clean truck
It's a GM crate engine, PN 19165628 - Chevrolet Performance Parts LS 5.3L 327CID Crate Engine - 327 HP / 347 Ft Lbs. It's a basic 5.3L engine with a few performance upgrades and a slightly hotter cam than the factory cam. It also has long tube headers and a free flowing exhaust from the previous engine. It also has a 2007 Silverado GMT800 electric fan and radiator which helps keep load off the engine. Without dynoing it, and I don't know if I can since I have an autotrac truck which requires a 4 wheel dyno, I'm estimating 350HP and 375TQ due to the tune and exhaust. I dumped a 2004 LS6 Corvette tune into it and so far it seems pretty happy with it although it will need some fine tuning still yet. I need to put a couple hundred more miles on it before I'll know just how well it'll run. Next spring it will be well broken in, and I'll be taking it by the local drag strip to get quarter times. After my house is up I also plan to install a TrailBlazer SS intake with an oversized throttle body, which is supposed to boost upper RPM performance without affecting low end performance. After that I'm done with it, and will go find a project to play with.
