    Looking at an RV 454 Friday...

    if it were me, and I dont have knowledge of bbc of any sorts other than sizes etc, but I'd take some tools with me, pull some spark plugs, check them out. I would even pull a valve cover or both actually and see what it looks like in there. If there was time or if i had any hesitation id take...

    Whats the best drop kit and/or combination for 20" rims?

    Hmmmm...may have to look into that, especially with the stepside bed...but I dont think it will have enough room...heard stepsides don't have as much clearance in back...but dont know for sure

    '81 GMC Classic Sierra won't crank

    Check your wires goin into your distributor. Also take a plug out hook up the wire, then place the plug up to a bolt or ground and have someone crank it over to see if there is spark. Check to see if your dizzy is still bolted tight, it could have been loose and turned out of time while letting...

    Dies on speed bumps/sudden spots

    Something else to check, my truck died on me I out of the blue and wouldn't turn over, it was just a simple issue with the wire that went into the distributor cap, I had messed with some wires just prior to driving it, it lost good connection and died, would crank but not start, I pushed in the...

    Mysterious black box

    Lol oops sorry, only reason I thought of this was because a guy who sold me a car a while back tried to convince me it had a performance chip in it for horsepower, I asked if he meant a programmer, he's like no it's just a two wire performance chip that was wired into the harness under the hood...

    Mysterious black box

    It's probably one of those ebay scam boxes that has a circuit board in it or a couple wires and a resistor like this pic. Supposed to give more hp and gas mileage, huge scam!

    350 Engine Build

    I'm currently trying to build a motor, but the shop that has it has been super booked up but I'm wanting to do a 383 but if my bore in my block is good I'll stick with a 355, but you can get a good set of aluminum heads for 500-700 and add 125-150 dollar cam and really bump it up some. All...

    What have you done to your square lately??

    updated grill, possible modding to come! Well I picked up a used gmc grill to change the look of my truck a wee bit. I'm most likely going to mod this grill with my own inserts like I did with an 03 ram I had a few years back! First pic before, second pic grey, third pic is my homemade inserts...

    Parts(misc, trim, wire, etc...)

    I found an alternator plug at Oreillys that I used for right now so it's not needed. Appreciate you looking and finding! If I change my mind I'll let you know.

    unused wires?????

    They were all cut and just in a spaghetti ball behind the master cylinder, I just wanted to clean things up a bit but kind of wondered why they weren't being used, it was bolted to the firewall just above the drivers side head but didn't go anywhere.

    unused wires?????

    Cool beans, I can clip it and dispose of it! Lol may go ahead and get rid of the other wires also since I'm using other gauges, eventually I'm going to just put in all new gauges, just wanting to get rid of the useless wires. Am really wanting to shorten some wiring up a bit. It seems I have...

    unused wires?????

    The ORN wire is almost certainly the power from the kickdown switch on the gas pedal to the detent solenoid on the transmission. Hmmm I stand corrected then, but it has me baffled now because it wasn't hooked to anything and my truck goes into passing gear when I tromp on it. I do know the...

    unused wires?????

    I think I figured out the single orange wire is for the oil sending unit! Which I don't have since my aftermarket gauge is connected there with a copper line.
