    Do I rebuild my SBC or swap for an LS3?

    Rebuild it. It has worked good all these years, so stick with it. Make sure that you don't try to build a half race car motor and expect it to run good and get decent mileage. Plan out your combination and improve it wherever you can without taking away from drivability. Maybe add a good dual...

    If you don't like it, don't paint it that color. Its too much work to do, if you aren't going to like it. Your grandfather would understand. Its yours now, make it your own.

    CB Radio Antenna Recommendations?

    Clear as mud!! haha. Not really. Thank you for sharing your knowlege. I am getting it. I am not going to go down the rabbit hole on the rf, I may never make it out. When I was a kid, "everybody" had there whip antenna mounted on the back of their tool box, now I know why. On my '85 there is an...

    CB Radio Antenna Recommendations?

    Well, my mind is blown already!! Thanks for the lesson. I didnt realize that it was all about wave length. So a whip mounted right behind the cab on the headache rack or the toolbox is about as good as it gets on a square body? What would be the difference between that and having a 4 or 5 foot...

    CB Radio Antenna Recommendations?

    I have a couple of old CBs that I would like to put back into service. I am not sure what type of antenna to use, and what is the advantage of one type over another. Dual short antennas, or a single "whip". Maybe somebody can explain a little bit about it for us that don't know how they work...

    Anybody wanna help me figure out what these plugs are for?

    A good wiring diagram will tell you what those wires are. I have found them on the Autozone site. You can probably find them in other places as well. Usually the plugs will only plug into one thing, so its a process of elimination. Also they usually only reach where they are supposed to plug...

    Extended front brake hoses for 6 inch lift.

    Add the amount of the lift to the length of the existing ones. (if its a 6" lift, add 6") If you want a little extra, add another inch or two. Just an idea...

    Newb here

    Welcome from NM. Tell us a little bit more about that K3500. Does it have the Dana 60 up front, 454?

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    This is what I came up with to do first start up on rebuilt engines. I can start them up and break in the cam and check for leaks and everything else, before I put the engine in a vehicle. That way, at least if it does wipe out the cam, I dont have all the time and labor of installing and...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    An Oldsmobile is no different than any other flat tappet motor, no matter who manufactured it. They all should get primed before initial startup. I remember making a priming tool out of a piece of 3/8" All thread to prime the one that I built over 30 years ago. I just ground some flats on it to...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    It sounds like you did everything that you were supposed to do when you put the cam in. I have done less than that before and didn't have that problem. I know you feel sad and disappointed that it didn't work out. At this point I would have to pull the intake, both valve covers and probably all...

    I would pull the lifters on those loose cylinders and make sure that they aren't flattening the cam. They get concave on the bottom.

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    I have a "stage 3" cam in my camper truck, 76 F250 with a 460. It sounds good, but I wish I would have put a little shorter duration one, for more low end, and maybe better mileage. Haha Maybe go from 7 mpg to 10. I do remember the Olds pushrods being pretty skinny. I dont think that they flex...

    The cam is a little long for a truck in my opinion, but not much. I am not sure about the springs, I didn't see where it spec'd that spring anywhere. It sounds like it should be a good engine. I am curious what you find out.

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    I used to run an Olds 455 in a '73 Firebird. I never had any trouble with it. I think it had a 268 adv. duration Erson cam in it, with matching springs, and stock rockers and pushrods. 402 lbs of spring pressure sounds kind of high for a stock engine. What cam are you running? Is it a high...

    Poll: What '70s/'80s pickup would you own if a GM square wasn't an option?

    I learned to drive in the old Fords. I still have Grandpas '76 F 250 with a 460 that he bought new.

    snap on help

    I would bet that they would gladly sell you a new box. Nobody repairs anything anymore. Dispose and replace is the new way. Not much profit versus the effort to get you the slides. You will probably have to do it yourself, and find something close online and adapt them to your drawers. For the...

    Anybody familiar with BluePrint Engines?

    Have you considered fixing the head on the existing engine? It may be a better engine than a cheap crate engine. What is the issue?

    454 stumbles at 2500 rpm

    Have you changed carburetor jets? The holleys are usually jetted pretty rich out of the box. What jets are in it? Did you blow the power valve with a back fire?

    454 stumbles at 2500 rpm

    Clogged fuel line or sock in the tank. Maybe at the valve to change tanks . Open up the fuel line and see if you can blow air through it. Check it in sections until you find the clog. Make sure the system has a vent as well.

    Engine temp isnt rising

    I know its frustrating not to know why, but it is a good problem that it is not getting too hot. Maybe the intake change made a difference. The stock big block 402 in my GMC only gets to the first mark on the temp gauge under normal driving with a 195 thermostat.
