Could someone recommend a Moog front coil spring number that will raise a 69 BB Camaro back to the original factory height. The car has stock spindles and the springs that were in it have a free length of 161/4 inches but it sits too low. I just installed a Moog number 638 but nothing changed. I would like to raise it at lease 1 inch.Thanks

My 69 Big Block is a tad high with Ron Norman/McHenry springs..........may I SEE pics of your 638 Moog 69 Camaro........

Maybe we should trade.

I have COPO clone and want stock height , but not HIGHER

Please considering cutting a #5536 to the height you want in trial fits!!!

It starts out as 488 pounds and I figure mine 1st, the open end clock-cut to stock and then one coil off it is about 525 pounds, BUT it is low!! Good clearance, BUT LOW!

Just keep cutting an 1/8 coil off the bottom of them until you like the "stock" ride height.

Ive read about MOOG 638's and just trying to get more affirmation before going through this drill again.................

Did anyone ever figure out what the correct coil springs are?

After much research, I still am somewhat in the air on what to use. I have found this much:

--On Jerry MacNeish's book on p. 167, there's a photo of a COPO 427 front coil spring with a "HQ" ID tag on the spring. Additionally, he claims on the same page that big blocks all received heavy duty suspension and used either "HQ" (part # 3955724) or "HW" (part # 3955728) front coil springs. I have no idea what the parameters are for the useage of each spring.

--Based on the fact I have been told that the weight of a COPO 427 engine is almost the same as the L78, I went to the 1969 Camaro Spring Determination Table. For the most part, it looks like a COPO would then use either an HJ (part # 3955727) or EA (part # 3955707) code spring. An automatic with power steering would most likely put the car into the EA code, depending on some other options the car has.

--I then went to Heatbeat City. I could not find the so-called Spring Code ID page they say is on their website, so I started at looking at what I know. I found what might be causing some problems with springs ordered from there.

I initially typed in the part number for HQ code springs. When I typed in 3955724, it pulled up a HA spring. While I am aware several codes had the same part number, the part number for an HA spring according to the GM guide is 3955725. Additionally, HA is a non-heavy duty spring.

I then tried 3955728, the code for HW. This pulled up a HJ spring. Again, the code for HJ according to GM is 3955727. So, I think this is the right spring to use?????

I was going to give them a call to try and get this resolved, but I'm guessing I'm just going to end up in an argument with them. Well, I won't argue, but nothing will get resolved.

I don't understand why someone who has restored a real COPO or even a clone, and got the correct ride height, can't simply chime in here. Is this secret info? I'm just getting frustrated by this whole thing.

From David Pozzi's great site and suspension info:

Moog 6312 - Stock SB spring 327 lb spring

Moog 6308 - Z/28 (SB) spring 380 lb spring

Moog 638 - BB spring

I guess I just don't understand how there can be ONE BB spring for all applications, when GM used several. It just makes it seem like getting the correct ride height is a crapshoot. I'll have some made if it means getting it right. I just need to know what damn spring code/part number to use.

Tom,

Read David's page. (Links in above post). You will get the idea. I have Hotchkis springs, which are MUCH firmer.

Tom

OK, will do. I'll have to print it out and read it tonight after work.

'69 Camaro.

350 Sport Coupe H-D, no A/C = 6312. W/ A/C regular = 638 and H-D W/ A/C = 638.

396 Sport Coupe regular = 638.

I still have my H-D 396 A/C springs up on the shelf that I removed from my car when I installed the clock cut and then cut one bottom coil 5536's
