If you keep that crossmember where it is - gusset it. It appears there is some flat steel from the frame that the square tube crossmember is welded to. It may seem fairly sturdy right now - but trust me with the load and strain on it it is not as strong as you might think. Gussets gussets gussets.

And Mark is right on your spring flex/shackles.

REDO on- Front Spring shackle :
The hangars took FOREVER to make. Just lots of drilling and cutting. I went through 9 cutting disks today. I need to get a torch setup next time !!
Here the new hangars are bolted in, all I did was lower the frame on to the top of the hangars and welded it up.
I made the spring hangars long and drilled another set of holes in the back so that I can always convert to 52 inch springs. I am currently running 58 inch springs.
** the springs have about a 9 - 10 inch drop. Big Grin **

gussets: where would you guys put them? I was scratching my head because I kept looking at it and thought it was pretty sturdy like kevin said. Im all in for reinforcements.

where at is my question.

The high steer cross over has a new angle now. I think it will work without any adjusting. But I never know. I am assuming a little bit of bump steer. The ram assist cylinder is next on the list of things to install.

Wayne, sorry but I forgot what you said about how tweaking the tie rod before welding up the ram brackets. Can I get you to write up the instructions on here for reference or make a 4x4 tech post of some sort?[COLOR="Silver"]

I have been rethinking the body fender narrowing/ modifications on the blazer
My thoughts:
1. ill loose storage space in the rear. (tires, recovery gear etc)
2. the initial purpose was to gain wheel approach angle. but i can get that by hacking into the rear fender... like hacking it off from as high on the he top of the wheel well all the way back. when I do my 63 inch springs in the rear, the axle will be moved back, giving me a better angle anyway.
3. Im still positive on the front modification to narrow it still for approach angle.

thoughts ? confirmation of my ideas/thoughts?

Ok.... so after a LONG night. The 454 is in. It took forever because Kevin's engine hoist decided to commit suicide. Luckily the hoist held the engine, I just wouldnt be able to raise it back up again. Another factor is that I installed the flex plate backwards. I noticed this when I had just finished bolting up the transmission. After I flipped over the flex plate and bolted it back on, lining up the transmission and motor was a PAIN because the engine hoist was done for. It died at 1 am this morning laying in its own pool of hydraulic fluid. Im sure it is fixable, just needs some new seals. My transmission decided it would joint the bleeding hydraulic fluid party and spilled about a quart...so anyway, I had to use the floor jack, some wood and about 8-9 hours to move the transmission back up to the motor. As I write this I have not slept yet!

My only concern is that the flex plate has some space between it and the torque converter. (about 1/4 to 3/8 of an inch)[COLOR="Silver"]

[/COLOR]also, what are the torque specs on torque converter bolts?

That is to much of a gap, you need to recheck everthing. You should have 1/16 to 1/8 gap.
Reply

do you think the torque converter was pushed in too far? what about putting in spacers (washers) and making sure thread lock is on them? (this sounds like a bad idea).
If the torque converter was pushed too far back.. im worried about the tranny pump.
If I put the bolts in now, and sucked in the torque converter to the flex plate, would it be set at the correct position?

all to be checked.. bellhousing is flush with the motor, fly wheel is snugged up with each bolt at 60 ft lbs.[COLOR="Silver"]

[/COLOR]the parts I used:
new flex plate from schucks, old torque converter that I re-used with the th400 and 350 tbi set up.[COLOR="Silver"]

[/COLOR]I have been doing some reading on the net and people are saying ad some washers to shim it up. and keep about a 1/8" gap before tightening it up

your torque converter will move out when you bolt it together. it seems a little much to me, but its been along time since I worked on full size chevy's. I wouldn't use washers myself. Call Porks Torques (907)373-4401 ask for porky, he helped me out allot with my problem and is more then happy to help someone over the phone.

So I have been thinking, to correct my steering...
I was thinking of swapping the tie rod and draglink positions on the knuckle because the drag link crosses paths with the tie rod due to me moving the axle up forward. I am expecting to not have as much leverage, but hopefully the ram assist will provide the extra needed force to turn. I will have to play with the positions this weekend and see what works best. Ill post up before and after pictures of what worked and what did not work.

Until then, any bright ideas ?

Also. the new valve covers on my 454 engine got in the way of my brake master cylinder ? (the big round thing) I think I am going to go with a hydro boost braking system off of my 86 parts truck since it takes up less room and will allow it to fit.

someone mentioned running my ram assist with the hydro boost. I'm not sure this would be ok. but.. any thoughts on that?

It will be fine. As long as your pump can handle it. Not sure that a stock ps pump will handle it.

ok so two things in this addition: steering and the flex plate wheel
Here I took a picture of the flex plate showing the spacing. It seems to be a bit less than when I looked before. Maybe I was just tired at the time.

And here is the new steering configuration:

Flex plate is normal, just tighten the bolts up. I can't really help yet with the steering, I will be attempting it in the next few months myself.

gimme a call or pm when you are ready to mess with your steering, I am interested in the set up you will be running. i might be able to steel some ideas as well Smile

I believe that the ram assist is next on the blazer's to do list.

Due to the newly arranged steering set up (caused by the longer springs in the front) The new position of the RAM will not be on top of the differential housing.
I would like to note that my axle housing is BENT. so I will be correcting this and putting a truss on the top of the axle. I think this is where the RAM cylinder will be mounted.

on another note I am going to be looking for an intake for a 454 and offroad holley avenger carb. goodbye EFI!!!!
