Q: I own a 1966 Chevy Biscayne with a 468-cubic-inch big block Chevy engine. It has 12:1 compression, Crane 298-degree duration cam, oval port cylinder heads, 926 cfm Holley double pumper on a Holley Strip Dominator intake, and an HEI distributor with an MSD ignition. The transmission is a Turbo 400 with a 3,500 stall TCI
I’m having a problem with the small block 383 in my Impala. The engine was new about two years ago, but I keep having problems with the spark plugs loading up with oil. Some of my friends say it’s a valve guide seal problem but the heads were new when we put the engine together. Others
Q: I have a 355-cubic-inch small block Chevy. The carburetor is a Holley 1850, 600 cfm with manual choke and vacuum secondaries. My problem is, the secondaries won’t open at any speed or rpm. When I hit the accelerator, I actually get a bog and have to let up. I can accelerate the car fairly well
Q: I’m putting together a disc brake system for a custom build. What can you tell me about setting up brake pedal ratio for optimum performance? Also, what can you tell me about master cylinders? Specifically, what do I need to know about the bore size of the master cylinder? A: On average, brake pedal ratio should range from
I purchased a ’68 Camaro basket case along with a pile of parts including what appears to be a 10-bolt rear-end that was not under the car. How do I identify this as either an 8.2-inch or perhaps an 8.5-inch 10-bolt? I’ve heard those later 10-bolts are stronger, but I don’t know much about them.
Q: I’ve purchased a new harmonic balancer for the small block in my 1965 Mustang. There are three separate sets of degree marks on the balancer. Which should I use to set my ignition timing? A: Ford used three different Top Dead Center (TDC) locations on its small block engines. So, some harmonic balancers have three sets
Q: I’m changing the valve seals on my 1973 Camaro. The cylinder heads are on the engine, and the engine is in the car. I’m using compressed air to hold the valves closed. Also, the Camaro has an automatic transmission. How do I keep the engine from rotating? A: This can be done by using an engine-rotating tool and
I recently bought an EZ-EFI throttle body fuel injection system from FAST for my ’70 Buick Skylark. I installed it according to the instructions and it started and ran pretty good for the first few days. I’ve noticed now that the engine runs very rich and it’s starting to load up the spark plugs. I’ve
Q: I recently installed a shift light tachometer into my 1969 Chevy C10 2WD pickup with a 250-cubic-inch 6-cylinder engine. The engine has an HEI distributor. Even though I followed the installation instructions carefully, I can’t seem to figure out this nagging problem. When driving, the tach registers anywhere from 5,000-7,000 rpm while cruising, even
I just purchased a ’64 Chevelle that is very close to stock. It has a 350-cubic-inch small block and a Turbo 350 that I’m happy with, so I’m thinking of improving the handling but only if I can do that without making it ride like a dump truck. I’ve seen rear sway bars on many Chevelles
