I’m thinking of installing an electric fuel pump in my ’69 Mustang. It has a small block and carburetor on it right now and eventually I’m going to run one of those self-learning fuel injection systems that bolt-on in place of the carburetor. It seems to me that it would be a lot simpler to

I have a ’55 Chevy that was my dad’s and now it has come to me. The car has a very tired 283 small-block in it with a TH-350 trans. I want to update it with a better engine and I just ran across a used 4.8L LS truck engine out of a 2002 pickup.

I have a ’72 Ford pickup that I’m slowly upgrading. It was originally a 6-cylinder truck and still has the original automatic I want to build this truck as a fun father- and-son project so I’m looking for suggestions. I’m thinking that a small block wouldn’t be a bad way to go. We don’t need

If I’m using timing control on my FiTech EFI, why do I need to buy the adjustable MSD rotor? Can’t I just lock out the distributor and then ensure the rotor aligns with the Number 1 spark plug terminal and make final adjustments to sync timing with the ECU using a timing light? Or, could

If you build engines, even just for fun, this has probably happened to you. The engine is fully assembled and you’ve bolted it in the car. As soon as the engine starts, you know you have a problem. Maybe it’s a horribly leaking rear main seal because it was accidentally installed backwards. Or maybe a

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

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
