This is a little different question but maybe you can help me with it. I have a small oil-free, 115-volt air compressor with a 20 gallon tank. It will make 150 psi but because the tank is small, it can’t keep up with some of my air tools. I was thinking of relocating it outside
This is directed to Jeff Smith – great article on ignition timing. I have a few questions. My problem is I can’t seem to get the timing right with either the initial or top end total and my engine is slow to start. I have a ‘67 Camaro with a 327 with double hump heads running stainless steel
I have a 302-cubic-inch small block Ford engine that I’ve inherited from a friend. It’s an older carbureted engine that I think is stock – it still has a 2-barrel carburetor. What kinds of parts should I buy like a four-barrel carburetor and maybe a big cam or something to make more power? I’m relatively new
I’ve read something about camshafts that some cam companies grind advance into the camshaft. I thought that you could only advance the cam once it was installed in the engine? How does the cam company grind advance into the cam? L.T. Jeff Smith: This is a great question. Everyone tends to look at the intake
A friend of mine suggested using a big-block oil pump on my small-block Chevy in order to get smoother flow and more volume with a stock volume pump? Will that work? D.B. Jeff Smith: It seems there’s quite a bit of confusion regarding oil pumps and oil pressure so let’s focus on what’s happening. We’ve
I just installed a new cam in my small block Chevy. The engine runs great, but I’ve noticed that at idle and at some cruising speeds the engine makes a noise that sounds more like a mechanical lifter camshaft. I bought a hydraulic flat tappet camshaft but this one sounds more like a solid lifter
I’m hearing all kinds of things about ethanol in fuel that will destroy a normal rubber fuel line. Should I change the fuel line in my car? I’ve heard that ethanol will even eat the steel fuel line. Is that true? What kind of fuel line should I use? B.E. Jeff Smith: Let’s start with
Now that the temperature is heating up and my engine seems to be running hotter, I’m reading all kinds of stuff on the internet about different coolants. I’ve also seen claims about additives you can just pour in and the engine will run cooler. Do any of these work? D.P. Jeff Smith: Over the years,
I’ve got a Chevy small block 350 with a mild cam (I don’t know what the specs are – I bought the engine used), an Edelbrock Performer intake, Holley 750 vacuum secondary carburetor, and headers. All of this is in my ’72 Chevy pickup. The truck runs great except for a stumble when you first
What’s the difference between a torque-to-yield bolt and a torque-angle bolt? I see these bolts used with newer engines. Are they the same thing? I’ve also heard that you’re not supposed to reuse these bolts. Is that true? Thanks D.T. Jeff Smith: First and most importantly, let’s distinguish between what we’re talking about. Your first
