    454 Big Block MPG

    yeah, i figured it would raise some eye brows. i tried to be very careful how i asked my question. granted, i am new to the square body world, but i’m pretty sure no one buys a square body with the idea that are going to make that little dutch girl smile. they buy them for the coolness factor...

    454 Big Block MPG

    i use my GPS everyday because it will route me around traffic issues. my speedo and odometer are pretty damn close even though the truck is sitting on 35s. i do not have 100% faith in my gas gauge. it gets down to ⅛ of a tank and starts bouncing. but what i do know, it is 33 miles from my...

    454 Big Block MPG

    i totally agree. i don’t think i am being unrealistic. it is a big block 454 after all and not a prius. if 5.3mpg is what i can expect, then i’ll quit worrying about it. i’m am totally a noob when it comes to square bodies and big, carbureted engines. however, i am not a noob when it comes to...

    454 Big Block MPG

    According to my fuel app, I am only getting 5.3mpg in my truck. Yes, I am fully aware of the “if you are worried about MPGs, you shouldn’t have got a 454” argument. I am also fully aware that poor gas mileage is a symptom that something is wrong. I have replaced the spark plugs, ran 2 tanks of...

    Driver Side Alternator?

    lol. one step at a time. right now i am just happy that she starts and runs. i’m thinking if i drain the coolant and clean the hole really good with alcohol or degreaser, i should be able to get it clean enough for jb weld to “stick.” when i cranked her up, coolant didn’t spray out of that hole...

    Driver Side Alternator?

    i ended up visiting summit racing and bought a billet alternator kit for a 454 big block. it works perfectly!!!! now all i need to do is plug up the hole and cinch down the rear of the alternator, and i am back in business!!!!

    Driver Side Alternator?

    i’m thinking i am just going to plug the hole, use the bottom bracket, and fab something to help support the alternator so it doesn’t vibrate and sheer the bolt. eventually i will pull the heads, but i am thinking i can “rig” it enough to drive it here and there. i want to rat it out anyway, so...

    Help With Block Casting Numbers

    I also found this. This number is on the bottom, just above the oil filter and close to the transmission bell housing.

    Help With Block Casting Numbers

    Allegedly, the engine in my 1986 GMC Sierra is a big block 454 that came from a 1986-ish motorhome. I am trying to verify, but I am having trouble with the casting numbers. The engine is still inside my truck, so I am doing some amazing contortion maneuvers to locate them. So far, the only thing...

    Driver Side Alternator?

    More of the story, the bolt was seized. When he used his EZ Out, it broke off inside the bolt. At that point, he decided to drill it out for a helicoil. That’s how I got to this point. To answer your question, yes the bolt is out. For whatever reason the tap isn’t biting. It’s like the hole...

    Driver Side Alternator?

    The alternator bolt in my truck sheared off recently. It did not have the bottom bracket and I guess the vibrations finally sheared it off. The bolt broke off below the surface of the block. A buddy of mine has an EZ Out kit and came over to help drill it out. Long story short, the drilling...

    Evaporator Coil Removal

    i recently purchased a 1986 k10. the previous owner dropped a 454 in her. the problem is, there are lots of go nowhere/do nothing wires and hoses in the engine bay. it looks sloppy to me. i would really like to get all of that crap out of there. one thing in particular that i am looking at is...
