    Help on Vibration/Pulsation Problem

    Sounds to me like maybe a fuel supply issue. I would check into the operation of the pump, fuel pressure, and condition of the fuel lines and filters. Look into the fuel tank with a flashlight and see if there's any obvious contamination. I had the same problem with mine, it would start and...

    Engine Problem 327/365HP; Timing Chain ?

    I agree with checking for bent pushrods, I would also check for splitting of the rocker arm ball seats. Did you check the timing? I've had distributors turn after high-rpm runs.

    Front Coil Spring Alignment

    Have you aligned it yet? This might effect it a little, try getting the alignment roughly where you want it then check it. Unfortunately cutting coil springs is a trial and error process to get the ride height right. I was fortunate to get it pretty close on my first attempt. If you're out...

    Valve Adjustment

    If your LT-1 is original, it has solid lifters and the lash must be set using a feeler gauge. I think you will find it very difficult to do this with the engine running. Hydraulic lifters can be adjusted with the motor running, but not solids. The engine should be hot, otherwise the clearance...

    Front Coil Spring Removal

    Depending on the springs he uses, of course, will determine whether the car is higher or lower. Either way get an alignment.

    Front Coil Spring Removal

    I recently pulled my springs. I tried to use an internal compressor but it wouldn't work. My best method has been to have the car in the air, put a jack under the control arm, and remove the bolts holding the control arm to the crossmember. That way there's no danger of damaging the ball...

    68 Hot Corvette

    If my car ever only reached 200, I think I'd be ecstatic. Why do you think there's a problem with 200 degrees? It's not going to run 160 with a 160 thermostat no matter what you do.

    Anyone Seen These Side Pipes!?

    The JCW style side pipes were on my car when I got it, shortly thereafter they were in the trash. Good sidepipes (performance and looks) aren't cheap, unfortunately. You should also check into Stahl headers and sidpipes. A buddy of mine had Stahl's on his car for years, and IMO they sound way...

    Options for fixed headlights

    I'm partial to the FIA style that GM used to provide to the race teams back in the day, with the bubble plexiglass covers. They're pricey, if you can find them.

    Has anyone used ARP permalock rocker nuts?

    It's mechanical. In your experience, you weren't happy with them because they were a pain to deal with? Did they hold their position though? Thanks

    Has anyone used ARP permalock rocker nuts?

    I have the rockers, and I bought new lock nuts from the General last year, however I believe the threads on my rocker studs are worn from years of having lock nuts threaded on them. I was planning to replace the studs, and was curious if anyone had any experience with the poly locks before I...
