Suckin' Air

Welcome to the Suckin' Air Section or better known as the Engine's Top End! Suckin' Air deals with the parts of the engine that suck the air into the engine. This section is divided into the following:

Ram Air - Here's how I created a custom Ram Air system for my 54 Pontiac. A Ram Air system is often mislabeled by manufacturers to mean a freer flowing air filter system. It's also called a fresh air system or cool air system. A Ram Air system has a scoop that provides cool air outside of the engine compartment. The air is forced into the engine by the pressure of the vehicle moving forward - it is a free mini supercharger.

Monster Air Filter - One problem with most standard air filter housings is that there is little room between the carburator/MAF housing and the top of the air filter housing. You might have a huge air filter but find out that there is very little clearance for the engine to breath. One option is to add a monster air filter that allows the engine to breath.

Heads - There are two parts of an engine that directly affect the performance: the heads and the camshaft. These two work together to get the air/fuel mixture into the cylinders and the exhaust out. Here's some info on the heads that I used and how I cc'd them to check the final compression ratio. I used Chevy 305 heads with a 400 block. You have to drill the extra holes to match the cooling for the 400 block.

Adjusting Lifters - Once your engine is back together and ready to run, you have to "adjust the lifters". What you are really doing is adjusting the gap between the lifters, rocker arms and valves. Here's a discussion on how to adjust the lifters using a number of ways and one that I found works the best.

Pushrods - There's several different types of pushrods used in a V8 engine and here's a discussion on how to identify the ones used on a Chevrolet SBC.

Honda Timing Belt Adventure - this is the adventure that I had when the timing belt broke on my 1990 Honda Civic. 2 days to replace the timing belt and check the valve clearance and 10 days to find out that the new replacement coil was bad...
