1970 c10 lq9 build
 

Starting on my c10 build with lofty plans. Any and all input is appreciated

Re: 1970 c10 lq9 build
 

Longed to shortbed conversion in the works

Re: 1970 c10 lq9 build
 

Frame shortened

Re: 1970 c10 lq9 build
 

Thinking on running mickey thompson 29x15r20 on 20x12 wheels. Maybe 29x18r20 on a 20x15. Any suggestions???

Re: 1970 c10 lq9 build
 

I would be a little concerned they might rub on the trailing arms. I have 31.5 X 18 on a 15" rim M.T. ST Radials on my 67 Chevelle and them suckers are fat.

Re: 1970 c10 lq9 build
 

I was thinking that might be an issue. I'm pondering if I should 4
Link it inside the frame and go coilovers. Just not sure if I want to go that far for a few more inches when the 29x15r20 tires are fat already. And know they will fit with just tubs. Saw a few this weekend at goodguys

Re: 1970 c10 lq9 build
 

Cab back on the frame. A whole lot shorter.

Re: 1970 c10 lq9 build
 

Looks good. I have an LQ9 in my 2003 Silverado SS. I really like the motor even in its stock form. (I believe it was rated 345/385 at the time.) Your motor definitely doesn't look stock! Doug

I'm the foreman at a fab shop and we just finished a lq9 swap into a 54 chevy pickup. I was so impressed with the power in stock form that I went with one for my truck. I'm hoping to hit 500 plus engine hp with mine. Can't wait to drive this beast. I would love to take it to sema this year but not sure if I can get it all done only working nights and weekends when I can and of course budget.

Re: 1970 c10 lq9 build
 

My built tranny rated for 650 hp.

Better pic of the lq9

Re: 1970 c10 lq9 build
 

Thinking on these wheels in a 20x12 rear

Re: 1970 c10 lq9 build
 

Awesome! Nice work on the frame.

Re: 1970 c10 lq9 build
 

Agreed. Awesome frame work any more close up pics of the shortening process? I am getting ready to do this to mine :D

Re: 1970 c10 lq9 build
 

very nice. my 350 for sale post in the classifieds is so I can go LQ4 or 9 in my own '70.

Re: 1970 c10 lq9 build
 

Sure do. Here are a few more. I've done it a few times at my work for customers. My advice. Measure a few different places. Level frame before and after. I clamp a piece of 1/4" wall tubing inside the cut to help line up before tacking and making sure frame is square. I am still going to add a plate to the inside for a little extra piece of mind but want to see where my Trans crossmember is going to land first. And then of course don't just weld the whole seam at once. 2" staggered stitches till you get it all welded. To much heat will warp the metal.

Re: 1970 c10 lq9 build
 

And 8" off the back

Re: 1970 c10 lq9 build
 

And thank you guys for the complements!! It helps that we do some crazy fabrication at my work. We do custom vehicles all the way to building semi trailers frome flat t1 steel plate. Here is a pic of a truck we are almost finished with. Our own custom designed air ride lift kit. What you guys think about this?

Re: 1970 c10 lq9 build
 

Looks like a wild ride.

Re: 1970 c10 lq9 build
 

In for the build as I'm too putting an LQ motor in my truck and realling wanting a 20x12 rear.

What's you mods on your motor?

Re: 1970 c10 lq9 build
 

Didn't have a bunch of time after work today. So just attacked the fuel neck hole

Re: 1970 c10 lq9 build
 

Well it's been a little while since I have had time to work on my c10. But here is what I did today after work. Fabbed up some motor mounts. And set the motor and Trans in for mockup.

Re: 1970 c10 lq9 build
 

Got my front tires in. Of course the rear are on backorder. I went with 29x18r20 mickey Thompsons. Going to be fun to squeeze them in there.

Re: 1970 c10 lq9 build
 

Well my rear tires finally came in yesterday. And they are wiiiiide. I love them. Going to have to go to coilovers which I pretty much figured. And now I have a brand new set of 4" drop coils that are no good to me. But it's way worth it when you look at these pictures.

Re: 1970 c10 lq9 build
 

Also. Looking for some advice on narrowing my 12 bolt. Going to do a disc conversion. So would I still need to do a c-clip eliminator or wouldn't the rotor and caliper hold the axle in if it broke. Any suggestions??
