    Humor me...I'm curious and can't find it anywhere/forums/images/graemlins/mad.gif

    My Chiltons shows 140hp and 240 tq at 2000 rpm...which doesn't exactly jive with the spec's page (J-code=151 hp)

    so how much torque does this thing put out??

    It depends on the year (fuel injection pump and head changes), but the 155 hp J model was rated at 285 lb-ft of torque.

    The early model 130 hp C motor produced 130 hp and 240 lb-ft of torque, from the factory.

    I got my information from www.thedieselpage.com from a 1997 article published there showing various torque and hp specs.

    I'm not sure where to tell you find that exact of information for your particular engine. You might have to find some GM shop manuals and see if they can break it down.

    Probably the easiest thing to do is find the date code on your block, to see what year it is. Then get the numbers off the heads, and then go to GM with that information to tell you for sure what you've got. The 6.2L was manufactured up until 1993, and each year had a little more power (from the factory) than the first.

    These are figures from my GM manual that covers '82-88 LL4 and LH6 motors.
    Highest gross HP was 1988 LL4 with 155hp/270tq.
    Highest net HP was 1988 LL4 with dual exhaust, 148/264@2200rpm. Single exhaust was 143/262@2200.

    Lowest net was 1988 LH6 single exhaust, 126hp/240tq@2200rpm.

    So what does your book say about an 85 J-code 6.2? Manual tranny and 3" single exhaust...

    It was from a K20 if that helps any.

    It only lists dual exhaust for '82-87. 1985 LL4(should be "J"code) as follows:
    Gross: 155hp/250tq@2000
    Net: 148hp/246tq@2000 rpm.
