I have a 496 Chevy and I want to go with a tunnel ram. What is the largest cam I can go with? It is going in a rat rod gasser. R.F. Jeff Smith: This is like asking “How high is up?” Generally, we like to answer questions that are a bit more focused, but
I have a 302 Ford in my street rod and have been using the Mallory Unilite distributor for years. Lately it’s been acting up and I can’t buy parts for this system anymore. What would be a good replacement for my small block? K.S. Jeff Smith: The answer is a little bit like the question
I have a ’72 Chevelle and I am planning for either a 700R4 or maybe a 4L60E. The car right now has a mild big-block 454 and I’m looking to put together a nice running street and highway car. I don’t drag race this car but I do want to be able to cruise down
I recently bought a FiTech Go EFI fuel injection system for my big-block Chevelle. The engine is a 468ci big-block with a mild hydraulic roller cam, a TH400, a warmed-over converter, and 3.55:1 gears in the 12-bolt. I used to run an 850 Holley. It ran great but always was rich.

Is there a cheap way to increase compression on my small block Chevy? I have a 350 small block with iron heads. I don’t know much about the engine because it came in the car. The previous owner said it was rebuilt and has a cam but he couldn’t remember the specs. The other parts
My neighbor kid just bought a ’69 C10 pickup with a 350 small block with a Holley carburetor an aluminum intake, cast iron exhaust manifolds, and a TH350 automatic. He’s been driving it around when the weather’s nice and since I’m the old guy in the neighborhood with a couple of hot rods, he comes
