    Mean sounding cams worth it?

    I am 14 years old I have a 1974 chevy k20 with a target master good wrench 350. Not the richest of the bunch, paid $300. I was wondering if installing bigger cams is worth it like. How much? What will I need to do? And will it be hard?

    Engine lunched itself...need advise

    '85 C10 From Houston

    Pretty nice forum here! Just got my 1985 C10 a few months ago, trying to fix some things the previous owner didn't get a chance to fix/improve. She has a 350 5.7 Vortec from Gordon's Engines (anyone hear good things about them?). I'm no mechanic but looks like PO let was slacking on engine...

    Hypothetical SBC question

    So I have a fun idea to wrap your heads around. Something that popped into my head a while back, and has been rolling around in there for a while gathering dust, haha. It's not squarebodys specifically, but about any chevy small block in general. Here it is: Hypothetically speaking, let's say...

    Clunking noise on start up

    Installed a new 355 I built into my k10 this weekend. Got everything wired up and went to start it and it begins to crank but then will make a loud clunking noise. It will then start to turn over again and do it again. Pulled the starter and checked to make sure it was mating with the flywheel...

    Opinions on an Engine Swap for 81 C10

    Right now, I have an extremely tired 305 and I'm ready to swap it out. Now I've bounced around different ideas, but not sure on which route to take. I think I've narrowed it down to wanting a 350. I don't want to do LS swap or big block. I've done some research and I've come down to: 1. Buy a...

    85 Engine Upgrade

    Hello everyone, I am looking at purchasing a new engine for my '85 K10 as the 305 that was in it is gone. The plan for the truck will be my regular truck to use daily and maybe even take some out of town trips. I want it to be reliable and start every time I turn the key. Originally, I...

    Best Carbs for Cammed 350

    Recently engine swapped my 85 C10, took out the stock 305 and put in a rebuilt 350 block with a massive cam and high compression pistons. Of course, my stock quadrajet off the 305 is too small now that she's pushing 300+hp (may seem small to some people on here but I'm excited!). Looking to...

    350 SBC Headers

    To my understanding, if you get headers for a small block you normally have to do something with the starter (get a smaller one) in order to actually fit headers onto your 350. If this myth is true, are there any good headers out there that i can get for the small block without having to...

    What Goes Here on my 1987 5.7L TBI Silverado Intake Manifold?

    I'm neck deep in replacing the gaskets on my 1987 Silverado Intake Manifold. I'm trying to buy a replacement for the fitting that is shown in this photo. Anybody know what connects here? I'm having a hell of a time explaining it at the parts store. It sits just to the passenger side of the...

    Chevy 350 light knock

    Got an 85 GMC K1500, 305 from the factory, swapped rebuilt 350 in it currently, it's developed a light knock! On start-up it's not there, after about 10 minutes of driving it's really noticeable (audible and feel it under your feet in the driver's seat) when braking. Now it could be that it's...

    Engine swap in '93 G20

    Hey guys, I'm pretty deep into a restoration on my '93 G20 van. It has a Pathfinder 4x4 conversion with 35s and has a ton of potential, but it needed substantial rust remediation and some body work. Once that is addressed, I'm going to put a new motor in it and have the transfer case rebuilt...

    ONE WIRE ALTERNATOR AND JUNCTION BLOCK??

    For my 1983 Silverado, I purchased a 140amp 1 wire alt., and the instructions say to just run a wire straight to the battery. Only thing I'm confused about is how the fuse panel will receive constant voltage. My factory wiring has a output wire from the alt running to the junction block which is...
