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

I am about to rebuild my first small block Chevy and I’ve been looking at parts and prices and noticed something. The bearing companies list several part numbers for things like main bearings for my 350 Chevy. The prices seem to vary quite a bit – much more than I expected. I’m going to assume

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

I have an Edelbrock 2×4 setup using the 500 cfm Endurashine carburetors for my 383ci small-block Chevy that I’m putting in a ’53 Chevy hot rod pickup. In a month or so I’m going to fire the new engine and I’m wondering if there are any changes I should make to the carburetors before I

I was working on my engine the other day when I pulled the distributor cap and noticed what looked like grease around the inside of the cap. But what really caught my eye was the strange buildup of crud on one end of each spark plug wire terminal on the cap. What causes this and

I have an ’85 C-10 pickup that we’ve installed a factory fuel-injected 5.3L truck engine. We bolted a TH400 transmission to the LS engine but I now realize that I don’t have any way to trigger the kickdown linkage on the TH400 trans. How do I do this so I don’t hurt the trans? R.G.

I don’t know if this is the right spot for a question but will a 16-inch electric fan cool a 1993 C1500 in the summer? J.P. Jeff Smith: The easy answer to this question is a qualified yes, but we’d be selling you short if we simply left it at that. The real answer to
