Header Installation Procedures
One of the most common problems with the small six is blown header gaskets and/or exhaust leaks. However they can be minimized by following proper installation procedures. The use of locking bolts may help, but even then, leaks can and will occur if you don't torque the header flange bolts (or... -
Selecting the Proper Valve Springs
Selecting the Proper Valve Springs Valve springs are one of the most critical components of your engine. It is very important to match the camshaft and it's potential RPM range with the correct spring rate. We will attempt to explain it in this article, but first lets go over some valve spring... -
Ultrastang - The Ford 9-inch rear end
FORD 9-INCH REAR ENDS A number of years ago, I set out to search the salvage yards in an effort to find a 9-inch rear end to go in my '68 Mustang. I knew that my up coming plans for my car were going to be way beyond anything the weak 8-inch rear end could continuously hold up to. After that...
Why This Matters
This article covers one of the most consequential — and most overlooked — decisions when building or modifying a Ford inline six: the hardness compatibility between your distributor drive gear and your camshaft gear.
Get it right and you'll never think about it again. Get it...
Overview
The Performance Distributors DUI (Davis Unified Ignition) is a complete drop-in electronic distributor that replaces the stock Ford breaker-point unit with HEI-style electronics, a high-output integrated coil, and a factory-optimized advance curve. It eliminates points, condensers, and...
Why Upgrade Your Ignition?
The stock Ford inline six used a breaker-point ignition system that was adequate for its era but has real limitations for modern performance use. Points wear, require periodic adjustment, and struggle to maintain a consistent spark at higher RPM. Upgrading to an...
Overview: Why Weber?
The Weber carburetor has been a staple of Ford inline six performance for decades, and for good reason. Designed in Italy and originally built for European performance cars, Weber down-draft carburetors brought sophisticated progressive throttle design and excellent...
Introduction
The Autolite 1100 and 2100 carburetors served Ford's inline six engines faithfully for decades — but if you're chasing better cold-start behavior, consistent fuel delivery at varying altitudes, improved fuel economy, and the elimination of endless carburetor tuning, Holley's Sniper...

Classic Inlines is a firm believer in using Jet-Hot ceramic coatings on our headers. While we offer painted headers, we highly recommend buying Jet-Hot Ceramic Coated headers, and our reasoning is very easy to understand.

When selecting your exhaust kit, or components, it's critical to size them appropriately. Selecting a system that is to small, will restrict air flow at high rpm's and limit your top end power. Selecting a system that is to large, reduces back-pressure, which decreases low end torque. We...

The 200ci engine is bored 40 over, with a dual pattern 264/274 Classic Inlines cam, modified D8 cylinder head, re-curved Duraspark/MSD ignition, high ratio rocker assembly, dual out Hooker headers, Flowmaster mufflers, and a custom built 4412 Holley 500cfm-2V carb with annular discharge.
Classic Inlines spent a couple days testing various carbs on our new aluminum head. The following data is the result of fourteen dyno runs made while we were there.
