Description:

The latest addition to our range of cylinder heads comes from a true US engine building mastermind. No one has spent more time dyno testing our cylinder heads and manifolds than Jon Kaase. Jon's experience testing our products over the years as part of the Engine Masters Competitions, have provided him with an in depth knowledge of what it takes to get the best results from our cylinder heads and manifolds. The knowledge gained from this testing has been combined with his wealth of experience as the number one engine builder in IHRA Pro Stock and has been applied to the new Kaase C-400. This brings to you the customer the very latest in Pro Stock technology to our C-400 cylinder head, making it the most advanced Cleveland Cylinder Head on the market today.

The C-400 comes in 2 fully CNC ported versions. At this level of performance CNC porting gives you the repeatable results needed to make the high horsepower level these heads are capable of achieving. The Kaase 2.85 C-400 has a 2.850" minimum cross sectional area on the intake port and the Kaase 3.1 C-400 has a 3.100" minimum cross sectional area. The 2.850" is designed to work with our 3V 3.5" 4500 manifold and is suited to 408+CI engines aiming for horsepower levels between the mid 700s to the low 800s. For horsepower levels beyond this, the 3.100" C-400 is designed to work with our soon to be released 3V 4.2" 4500 manifold.

The 2.850" C-400 flows 400cfm by just .750" valve lift with almost 340cfm at .500" lift, whilst the 3.100" C-400 flows nearly 350cfm at .500" lift.

To achieve these exceptional results, the Kaase C-400 comes with an all new combustion chamber as well as intake and exhaust port layouts. Both the inlet and exhaust ports have been raised. The exhaust port is just a further .100" higher than our 3V exhaust whilst the intake is .200" higher. The chamber is a very shallow and extremely efficient design with a total volume of just 45ccs. Valve angles remain standard Cleveland but the valve positions have been moved to optimize their location. These changes require a custom piston with at least a 1.200" compression height. CP Pistons have digitized the new chamber profile and we have custom pistons readily available. The relocated valve positions also require longer intake and exhaust valves. Using our custom valves will net valve spring installed heights in the 2.100" range, dependant on the choice of collets and retainers.

Although this cylinder head is designed with shaft mounted rockers is mind, Standard Cleveland roller rockers will work with this cylinder head and stud girdles will need slight modification on the intake side for them to fit.

Valve sizes are 2.190" on the intake and 1.650" on the exhaust. Our standard valve guide size for the C-400 is .3125" (5/16), but the heads can be ordered with 7MM and or 11/32 valve guides if necessary.

So when you're looking for the ultimate SBF or Cleveland cylinder head look no further than Jon Kaase designed C-400 for proven results and outstanding performance.

In keeping with giving you results and not just air flow numbers we have already run the 2.850" C-400 on a customer’s engine with outstanding results.

The engine was a 3.750" stroke, 4.155" bore, 6.200" rod combination with 12.5-1 compression. The roller camshaft was designed primarily for nitrous, as this was the ultimate goal of the customer and yet this motor made over 800hp and 590ft/lb of torque normally aspirated.

So far this combination has run 8.60 @ 155mph in a 3300lb car on nitrous.
