Re: 1949 Chevy 3600 into a daily driver
cool congrats. Yeah bugs takes months at time to get to. Life gets in the way. I'm in your boat, insanely high strung cause I have such a full plate all the time. (is a good thing cause it keep the fire lit to get a truck done, as we all know they can linger for years). Air pressure is the key, def doesn't effect the height all that much. Was something I was sooo unsure of when setting up my truck. I ran my rear sleeve bags at about 2x's the amount of pressure some guys ran. When my truck hit the sweat spot it was very enjoyable. You'll get there, enjoy it relax and kick back and say yup, I built that.
As for fuel pressure. If you have a gauge with fluid in it, there should be a bleeder on the back of it, try that and see if your gauge pops back up.

Re: 1949 Chevy 3600 into a daily driver
I have had a lot of air systems on trucks. a LOT. usually when I have a stiff ride its because there is too much air in the bags. this can happen two ways, the first is me filling them too much for ground clearance. I will usually ride as low as I can to have the lowest spring rate, and make a mental note of big bumps and cracks in the roads that make me bottom out, which isnt as bad as it sounds, after 6 months you will see a dip or bump coming and wont even wince. it wont kill you to let some air out and see if maybe you were rolling around "locked up" which is the hydraulics guys term for full stroke that leaves you without any spring.
the second way is related to setup. I always set up the bag so that it squishes completely, I mean the last breath of pressure comes out just as the bag hits the internal bump stop. If you install bags where the mounts arent high enough, thats easy to figure out because the truck wont hit the ground. but if you set them too HIGH, there is all this volume in the bag that isnt related to lifting the truck and requires pressure to fill before any lifting even occurs. this is also pretty easy to identify, measure the squished height of the bag from plate to plate and make sure it is right at the min height of the bag. if you cant measure with the bag in, take it out, or my favorite shortcut is to put the tires on a 2x4 or 2x6 and let the air out. if the truck keeps going down past the tires, you have too much wasted drop, which will limit your lift too! this shortcut only works if you have extra stroke in your suspension, so dont try it if your tie rods just kiss the frame at full drop. other than that, shocks are a big deal. I use as long a shock as I can. also alignment can make the truck ride rough. good luck!

Re: 1949 Chevy 3600 into a daily driver
Well the truck does for sure need a 4 wheel alignment. That could be a huge part of it.
The bags are set up to fully deflate at full squish. The truck will ALMOST roll when fully deflated. I will have to do some playing around once it is road worthy. CPP could not guarantee me a prop valve this week so I just ordered one. It will be here on Thursday!! One other thing I noticed about the air ride is how much different in ride height a certain psi can be.......and how much all 4 bags affect each other. Still trying to consistently get to my desired ride height without getting out and checking. :-) |

in my first bagged truck though, it was a RELIGIOUS experience to watch the pressures. how is your desired ride height anyway? a good rule of thumb is to measure full travel and ride height should be in between 1/3rd and 1/2 travel, otherwise the spring rate gets too high. you can always lift for driveways haha

edit: also, I saw your post about the wheels being too far forward in the wheelarches. it looks like you dont have any caster or camber shims installed yet. your wheels may be castered forward and this will give a pretty stiff ride. on all the s10s I have owned there have always been more shims in the back of the arm than the front, which will pull the wheel back slightly. if you are set at zero camber at your ride height, dial in a little, it will help with turn clearance and may be better for the tires than a zero setting. camber doesnt ruin tires, toe and camber together do.

Re: 1949 Chevy 3600 into a daily driver
I put flow controls on my lines so the front and rear go up and down at the same speed. From sitting on the ground I hit my switches for about 1.5 sec then I look at the running board to the ground from my seat to judge height and go. Ride height is 3" 1000mi have not bottomed out on the road. I just slow down for train tracks and stuff.

Re: 1949 Chevy 3600 into a daily driver
This is a picture of the bag at a little over ride height. Pretty sure at ride height the LCA is parallel with the ground.

Re: 1949 Chevy 3600 into a daily driver
I rode about 4" off ground on my 49', rarely a problem and where I live, dirt roads and crappy east coast paved roads, its was fine. My buddy has a 54' belair that previous owner put a camaro clip on ): he can't hardly even bag it, but for now he is running a narrow set of front rims. So what you could do is choose different rims and even a 14" rim like I run, with my WWW they are 26" tall. I know that is prolly not in your to do list, but that is an option if turning becomes a headache.
Be careful to whom you take it to for alignment. Most shops don't know jack, esp with your IRS they will in awww. There was only one shop (an hour from me) that had a machine capable of aligning a lowered truck with those fenders.

Re: 1949 Chevy 3600 into a daily driver
question, do you have a pic of the total air up? just curious. my truck only had 6" up front and 5" in back max air. I didn't have time to really dial in the back bf it left. I personally feel like your ride height can be a tad lower and I'd be curious to know your pressures.
lastly, LCA at ride height is def the general rule of thumb, but look at a daily s10 for example, the LCA are not level. My 49' was the same way. So I wouldn't stress on that, ride it where it feels most comfortable.

Re: 1949 Chevy 3600 into a daily driver
I was able to ride my front at 50-60psi (airlift 2600's) but my back was at around 80ish. I had sleeved bags and really needed to just dial in the back. I did put 2" risers under the bags which made it worse cause the shock was maxed out and not doin anything. I drove it that way once (on way to meet new owner) I hated the ride but bf I added the blocks it rode great. The idea to add blocks is to get the bag pressure down, which I'm sure would be good if he gets longer shocks. Also by doing that you are theoretically able to get more lift with lower pressure. Even with more pressure in rear which is opposite of all bagged trucks I'v heard of, it still rode great.

Re: 1949 Chevy 3600 into a daily driver
First step is get the alignment squared away. At the recommendation of a local circle track guy I bought a cheaper Caster/ Camber tool from Speedway. Gets good reviews and is cheap enough to try....

Re: 1949 Chevy 3600 into a daily driver
Still messing around with little things.
I had a slight miss in the engine that was getting worse. Turned out to be a dead cylinder. One thing led to another and now here I am. ![]() Found evidence of a vacuum leak on the dead cylinder. Hope to have it back together this week. |

Re: 1949 Chevy 3600 into a daily driver
you thinking rings on piston or head gasket, heads, valves? that sux. I always do a compression test before I fire them up, then afterwards too. Sometimes with cast rings they need a bit to seat but doubt its your problem.

Re: 1949 Chevy 3600 into a daily driver
I wonder if its a head or gasket problem since you felt like you had some moisture in oil. I'v had a couple engines fail compression test. Last one had a broken piston land.

Re: 1949 Chevy 3600 into a daily driver
I have spoke with a bunch of people about the motor issue, gathering info and just trying to learn.
Troubleshooting is tough when a guy never finds a smoking gun. The original water in oil issue was caused by me missing a couple bolts on the intake during the torqueing sequence. That was on the rear passenger side. This issue is #7 cyl, rear drivers side. I am hoping fresh gaskets and a thorough torque sequence will solve the problem. [IMG] ![]() |

Re: 1949 Chevy 3600 into a daily driver
a vacuum leak would not cause a dead cylinder. just really bad A/F mix.... water in the cylinder would! -
Check compression after you get it together, then check spark at each cylinder doing the old plug grounded to block test. You may just have a bad disty cap or wire.

Re: 1949 Chevy 3600 into a daily driver
Id def make sure the head isn't cracked bf I put it back on. Just make sure everything is clean and torqued right. Put sealant on your head bolts and wait a day bf you fire it back up. Its ok to retorque after a day too. I'd then do a compression test. just put the gauge in that cylinder and disconnect your distributor wire, crank it over and see what it has. If you have zero or very little compression, Id say your piston or rings would be the next problem. where they replaced?

Re: 1949 Chevy 3600 into a daily driver
Bolted the motor back together over the past couple days.
Reinstalled the intake with new gaskets and using RTV on the ends. All seems good at this point but I have yet to put miles on it. |
