Anyone know if replacing stock C3 rear spring with a fiberglass spring will make the ride less harsh?

Just installed an Edelbrock #2101 intake on my 76 C3. With the stock Q jet and air cleaner I had sufficient hood clearance. About a 1/2 in on the front edge. :thumb

Just had to vent. Who ever thought it would be a good idea to put a side post battery in a battery box behind a seat? Ever try to jump start or just disconnect a battery terminal? WTH.:mad

I know there have been several discussions on the issue of hot foot wells of a C3. Does installing shut off valves to the heater hoses under the hood really help this issue. I have installed insulation everywhere and even wrapped the exhaust in that area, still have toasted feet.

Anyone ever put a Jet Performance Quadrajet carb on a small block C-3? I would like to stick with a Quadrajet so that I can use the stock spread bore manifold. My stock carb is just worn out and I thought the Q- jet would be more cost effective than going with a Holley and changing the manifold...

In my 76 the oil pressure gauge reads high almost pegged at 80. I checked with a direct press.gauge and it is 40-50. I replaced sending unit and gauge and still have problem. I checked continuity in the wire from the sending unit to gauge. Any help would be appreciated. Thanks

Anyone ever have a headlight come open on there C3 while driving with the lights off? During a small burst of acceleration I noticed the left head light come up

I solved the problem of one headlight way slower than the other to rise by replacing a relay valve. Is it normal for one to go down before the other to go down when they are turned off?

I have a vibration coming from the back of my 76C3, it only happens when sitting at idle backing out of the garage or just sitting at a light. I checked to see if the exhaust was maybe touching somewhere and it is fine. I thought maybe the brakes but I don't feel anything in the pedal. I...

Does anyone know if you can use the rubber weather strip from a 72 C3 for the rear window of a 76? I understand that 73-77 they used some type of sealant instead of a weather strip type gasket. I just thought it might be easier to install with a seal.

Anyone know where I can get a reproduction data plate that goes in the upper forward corner of the drivers side door jamb? Mine got misplaced during repaint several years ago.

Just a quick warning on some C3 vettes, The radiator drain plug can really get seized. After using suitable penetrant and much colorful language I was able to get the plug out. Unfortunately the threaded ring that is brazed into the radiator that holds the plug must have gotten a bit tweaked...

Will the optional tire size 255-60-15 for the 82 C-3 fit my 76 without any issues?
