On a 71 c10 step side

I will add that a big block up front and a 5" drop will require a pretty stiff spring to keep the crossmember/lower a-arms from kissing the concrete, as it will likely only be a few inches off the ground.

It will be a small block the big block was in my 90 as truck I had

I will be running a 6spd and some type of small block around 400 to 450hp. Lowered 4-6 to 5-7 not bagged. 20 in wheels was thinking 20x8 and 20x 10 or 12 rear. It's a coil spring truck. Not dead set on any of it other than a small block and stick shift truck lowered. I am open to any ideas.

I'm not on 20's, but my truck is lowered roughly 4.5" (spindles/springs) up front and 7.5" in back (6" spring, 1.5" block), but the big block adds a little more weight up front, so it's really closer to 5" (actual measurements, not guessing). I started out with a 2.5" spindle and 3" CPP drop spring, but I dragged the arms a couple times, so I went with stiffer Hotchkis 2" spring that's 1400#/inch and they keep everything high and tight .

What tire sizes are you wanting to run? My tires are 26.5" up front and 27" in the rear as they sit on the truck. Just something else to consider. Then you have to decide if you're going to run inner fenders, and then backspace of the wheels to make sure it all clears, and the list goes on...

I want the truck lowered and then I will build around that don't want to build around a set of wheels. Like I said before this is my first truck so I am new to all of this. I am open to ideas. I may. E going about this all wrong so if I am please steer me correct.

What size are your wheels . I love your set up.

[BossHogg69]

19x9 in front, 6" backspace; 19x12 rear, 6" backspace. The rear end is narrowed 2" (it was already the narrower 67-70 six lug 12 bolt housing, and I cut 1" more off each side and swapped over to Ford 9" style housing ends)

Tires are 275/35 front, 345/30 rear. I'm running stock inner fenders. Nothing rubs, drags or scrapes.
