'66 12v swap question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hey guys, I'm building a '66 SWB stepper, I'm going to Z the frame, notch the back, box the whole frame and put my 1990 12v in it. my question is

do the oil pans on the 12v's hang lower than the K member? if so how much?

i would mock it up and see for myself but my 12v is buried in my back shed till the snow is gone.

thanks in advance

Jimbo, I've only done 1 2wd 67-72 so I don't have a lot of info. Usually the bottom of the pan is even or just above the bottom of the cross member. You can always cut the pan and modify it and the oil pick up tube. I've done that several times. Or you can place the engine up higher in the frame but that might require floor board reworking.

That’s no problem, a inch or so below is fine, I can modify the pan or raise the mounts easily. I just wasn’t sure if it was a 6 inch drop below the cross member. I’m wanting to lay frame with a Cummins. So your news is good news.

Sounds like a cool project to me! Start a thread on here when you do. I'd like to follow along!
