An Affordable Way to Add Up to 250 Horsepower

Nitrous oxide is an affordable way to add horsepower. Nitrous Express MainLine Carbureted Nitrous Oxide Systems make it even more affordable to add up to 250 horsepower to your carbureted engine. The plate-style systems have jetting for 100, 150, 200, and 250 horsepower and come in versions to fit squarebore, spreadbore, and 4500-style carburetors.

Big Airflow That’s Emissions-Legal

It’s not every day that you can get emissions-legal cylinder heads that flow over 380 CFM at .700-inches of valve lift, but AFR’s LS3 260cc Mongoose Cylinder heads certainly fill the bill. Designed for LS engines with a 4-inch or larger bore, the fully assembled Mongoose heads have CNC-machined runners and combustion chambers, and are ideal for street and mild race engines that make power up to 7,000 CFM.

Build a Strong Foundation for Big Horsepower

Whether you like the strength of traditional cast iron or the weight savings of aluminum, Speedmaster has a bare engine block that will give you a strong foundation for engines making 1,000, 1,500, or even 2,000-plus horsepower. Available for Chevy, Ford, and Gen III Hemi engines, the blocks have features like four-bolt main caps, a priority-main wet sump oiling system, and extra-thick decks for a reliable head gasket seal.

This is one area of the interference for the Jesel belt drive on our Gen VI Bow Tie block. The fix was simple…

Let’s assume you bought a brand spanking new block and it’s back from the machine shop. It’s machined and it’s ready to go. Or is it?

Probably not.

You need to prep it for assembly. That involves cleaning the block and installing the various hardware pieces (galley plugs, oil filter adapter(s), cooler lines and so on).  Another issue is the fit of various components used in or on the engine–they’ll likely require a test fit.
