    I just got back from putting my K5 on a Dyno,
    Here are some numbers:
    When I first got there:

    WOT - Max Power = 265.18 ,
    MaxTorque = 361.30 ,
    Air/Fuel Ratio @ WOT = 16.6 - 17.1 ( I found out this is REAL BAD )

    When He was Done:

    Max Power = 285.44
    Max Torque = 389.63
    Air/Fuel @ WOT = 12.1 - 12.6 ( Now sitting in the sweet spot )

    All in all it was a good experiance seeing my rig on that dyno howlin like a mad dog at WOT.Soory no pics. My wife has the cameras on her out of town trip....

    Honey Do

    Luckily mine is understanding, the list is so long now I can't even see the end of it. My main job around here is to kill bugs and keep the mice away, which I do very well and that lets me play with my truck!! What does a dyno run cost these days? Later J.

    Well this shop gets 100 bucks just to toss it up on the dyno fer 1hr and do 3 standard tests. The from there if you wana tune it's 100 bucks an hr. I was there about 3hrs and cost me 200 bucks. Not like they had a stop watch going..good shop with regular folks running it and having a good time doing so...wish that was my shop..thats fer damn sure!

    Dyno

    It's a nice way to find out actual numbers, well it's Saturday morning my play time. I want to get my timing chain in, it s#cks I have to crane my motor up just to do this work every time. Wish this crossmember wasn't in the way. I gotta find a better way!!!! Later J.

    Well J,
    yer probly out side right now but I wanted to show you what I did to cure your issue of yanking the enigine just to take the tin off.

    I replaced my crossmember with a 73+ 4x4 truck/blazer SBC crossmember/engine brackets. I took an extra step and installed ORD's enine mounts. The black paint in the pic kinda blends all the steel togeather but if you find the bolt heads then the pieces are visable:D
    Now I can drop the pan with ease:D

    Oil pan drop

    Do I understand you correctly, you don't have to hang the engine from the rafters to drop the oil pan???? If this is correct I'm off to the junkyard, thanks Burt. Later J.:bow:

    Yup, thats the ticket.
    It swings forward under the front instead of our stock version that swings right under the oil pan.
    you will need to dril some holes. Two of the original holes line up with the 73+ crossmember to get you goin in the right spot.
    This is the artical i got the idea from.

    In this pic you can see the bolt head & nuts on the frame were the new crossmember and frame horns bolted to the top of the frame above the bumpstop bracket and then the two at the bottom dead center in the photo.

    crossmember

    Does the upper part of the motor mounts still bolt up as stock or do they have to be modified. I just bought new prothane mounts and I want to use them??? Thanks J.

    Motor Mounts

    Actually, I've been trying to find out if that new crossmember ORD makes would fit my first gen. sounds like from what your saying it could fit. I'll look the motor mounts up in prothanes cat. but I believe your right. I'll give someone a good deal on these mounts and buy new ones. Did you also have to get the top pcs. of the crossmember, the ones below the actual motor mounts??
    Thanks for the help Burt, you better go straitn up the house before the other half gets home, aleast get rid of all the beer cans haha Later J.:haha:
    Reread your original message and got the answer I was looking for on the upper pcs.

    Nice jump after they got done with it - sounds like it was worth the money spent. Once you left could you feel a definite difference on the road?
