Miller812 Posted February 4, 2012 Report Share Posted February 4, 2012 can the 6.2L be swapped directly into our trucks?? Quote Link to comment Share on other sites More sharing options...
soldadoblanco Posted February 4, 2012 Report Share Posted February 4, 2012 (edited) can the 6.2L be swapped directly into our trucks?? If im not mistaken only an lsx 6.2 block can be directly swapped into our trucks....the new ls3 6.2 would need more work because the transmission is controlled by a tcm which our trucks don't have Edited February 4, 2012 by 2drchevyss (see edit history) Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted February 4, 2012 Report Share Posted February 4, 2012 Might as well just build a 408? Quote Link to comment Share on other sites More sharing options...
04CHASE Posted February 4, 2012 Report Share Posted February 4, 2012 (edited) If im not mistaken only an lsx 6.2 block can be directly swapped into our trucks....the new ls3 6.2 would need more work because the transmission is controlled by a tcm which our trucks don't have the transmission and engine are completely separate so any engine can be mated to our stock 4l65e or to those who upgrade to the 80e. any who all , gen 3 engine are a direct swap(ls1,ls6,lq4,lq9) the cam sensor and knock sensors are different on the gen 4's (ls2,ls3,ls7,lsx gmpp block) and need a relocated set of knock sensors and a different front plate with cam sensor and modded harness to work properly , and after having done it the knock sensor dont work as well in the new position on the side of the block. to the original poster , figure your budget and there may be better options than a crate motor . upgraded stock motor . (stroking , cam and heads will be more power and direct swap ) Edited February 4, 2012 by 04CHASE (see edit history) Quote Link to comment Share on other sites More sharing options...
2001silverado364 Posted February 4, 2012 Report Share Posted February 4, 2012 (edited) What about the crank sensor, does the reluctor wheel not have a different amount of teeth between the to gen's? I wanna say 24 for 3rd gen's and 56 for 4th, but I could be wrong. They make an adapter for that...I think. Edit. I was wrong 58, not 56. Here's a link. http://www.ls2.com/forums/showthread.php?t=834483 Edited February 4, 2012 by No SS (see edit history) Quote Link to comment Share on other sites More sharing options...
JC03SS Posted February 4, 2012 Author Report Share Posted February 4, 2012 Thanks guys I appreciate the info. I don't really want to put a supercharger on it because it does have 89000 miles on it. But the engine still runs really good. Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted February 5, 2012 Report Share Posted February 5, 2012 Still voting 408 build, probly cheaper and less of a hassle, and awesome! Quote Link to comment Share on other sites More sharing options...
tburkdoll Posted February 5, 2012 Report Share Posted February 5, 2012 Where does someone draw the line between a new motor and rebuilding your current one? As in a mileage line Quote Link to comment Share on other sites More sharing options...
JC03SS Posted February 5, 2012 Author Report Share Posted February 5, 2012 Idk now that answer. I am gonna do something tho I'm sure I'm gonna drop about 10 grand in it no matter with way I go with it. It's my daily driver but I only put about 150 miles a week on it. I want it to be pretty reliable as well. I want to keep the truck for as long as possible so that's another reason I was leaning toward the new engine.
