My winter project

[7D2N]

Slow progress but still moving along. I have the old lift out and working on a new 4" with rear blocks, the old springs are shot but found a set of rear that will replace the ones if have.

[7D2N]

I worked with two sets of rear springs replacing broken leafs and making a good set, rear blocks and springs for the lift are set.

Nice work! Who did you get the front lift springs from? Manufacturer I mean.

Spf79, the lift is from Rough Country and came with front springs and rear blocks. You Jimmy project is looking very good I will be checking in on it.

35" tires and 3.07:1 gears will make for very sluggish acceleration and power. You may have to consider changing out differential gear sets in the future to something like 3.73 or 4.11. I had 32" on my 350/350 Blazer with the stock 3.07's and it was a dog.

I have the 350 cu.in. motor and th350 auto trans. Is the 3.07 ratio ok for hyw 60/70mph?
Thank you guys

I think you will be good on the hwy with the th350, 35's and 3.07's. Probably a bit of a dog around town... but if you are just cruising... who cares?

This has been my experience. I had a 79 k10 swb in college with a 383 built with torque in mind, maybe 350 hp on a good day. I ran this motor with a th350, np205 and a 10 bolt that had 3.07 gears. It had a 4" lift with 33's.

It was not a dog around town, but slower than I liked, between 30 to 50 mph it was quick... IMO. On the hwy, at 70/75 it felt like it had good power and I could get up to 80/85 without much trouble. It had nothing past 85.

That truck liked to cruise at 65, it felt like a small push to get up to 70/75 and maintain. I don't think those tires measured out much past 31/32" even though they were 33's. Thinking about it, if you are looking for nice hwy cruising you might be set up perfectly with the th350 and 35's.

I also had a 74 blazer in high school that had 33" tires that actually measured out to 33 inches... with 4.11 gears and an old dog of a 350. It liked 55, and did not like 65. Based upon that rig I am going with 35s and 4.11 gears because I will be driving around town most of the time, 45mph at the most. If I was going to drive on the hwy a lot I would go with 3.73 OR 3.55's.

I would not stress about the 3.07's, change them when it makes sense to do so. Or keep an eye out for a 3/4 ton set up for cheap. Those normally have 3.73 or 4.11.

I had some time to work on the front hubs and because someone thought big screwdrivers may remove the spindle nuts. I ended up getting a spindle nut kit and now good to go.

[7D2N]

I had some time when the super game was on so... the motor needed to come out and now I'm not sure of the next steps for trans and transfer case removal, they need some cleaning but I could use some guidance of the next move to get them out.

Thanks

Do you know who makes that row bar? Door panel looks good all black. And last who makes that body mount kit.

Thanks

I looked for suppliers or manufacturers that sold this type of roll bar and I did not have any luck, this is the second one I've had and both were bought used. The body mount kit is from energy suspension and pleased how it went in, oh and thanks on the door panels I think I will go with black and trim no wood grain.

Thanks for the great post, I am just starting my 71 blazer.

Jr. post some pictures I would like to see your blazer, starting is the best part and the things I have learned here has helped me a ton. Many people willing to share knowledge.

Thanks

I found out that truck bed liner will come off the the hatch with a little heat, prying and pulling but fairly easy to remove. I was also surprised the hatch was in pretty good shape.

Well after rolling around on my back scraping, grinding, and sanding the underside of the tub and frame it's time to paint. I used a roll-on satin black on the underside of the tub and can spray the frame. Trans and transfer case ready to go back in.

[7D2N]

Painted under side of the tub and frame, for a driver truck what do you think white or black firewall?

[7D2N]

Moving to engine stuff, looks pretty clean inside but a previous rebuild had the cam break in fail. Need to get to the machine shop.

[simicrintz]

Thank you, and glad it helped. No particular reason that I recall, but I think would look nice as well.

[7D2N]

The engine went to the machine shop and had a few things done will have it this week. New home is ready.

[Tom Vogel]

Wow... you’ve made a lot of progress since I saw you last!

[wthompson]

Looks good like the process.

[simicrintz]

So you decided on the white firewall; looks good!
