What does a camshaft and valvetrain determine?

When it comes to camshafts, there are probably more misconceptions than there are facts. We’re here to dissolve most of the myths and get you headed in the right direction on your ford ...

Why do we need a mechanical cam?

A mechanical cam gave us the precision needed for high-RPM operation, because mechanical lifters don’t pump up at high revs. We adjust the valve lash and watch what the engine does at high RPM. Mechanical lifters are nothing more than the middle man between the cam lobe and valve.

How much valve overlap does a street engine need?

Why is low end torque harder to achieve with a small block?

Low-end torque is harder to achieve with a small-block because these engines generally sport short strokes and large bores. Your objective needs to be more torque with less RPM if you want your engine to live longer. High revs are what drain the life out of an engine quickly.

Overview

The first generation of Chevrolet small-blocks began with the 1955 Chevrolet 265 cu in V8 offered in the Corvette and Bel Air. It was based around the size and style of the Ford Y block engine that was introduced in 1953, with some revisions incorporated into the design.

3.876 in. bore family (1957–1973)

The 283 had a 3.876 inches (98.45 mm) bore. The stroke of the 283 was 3 in (76.2 mm), like the 265.

4.000 in bore family (1962–2002)

Originally intended as the performance block, this engine family through the 350 cu in (5.7 L) became an all purpose engine that saw use in many applications from Corvettes to vans.

4.125 in bore family (1970–1980)

The 399.9 cu in (6.6 L; 6,554 cc) is the only engine in this family and was introduced in 1970 and produced for 10 years. It has a 4.125-inch (104.8 mm) bore and a 3.750-inch (95.25 mm) stroke.

3.736 in bore family (1976–1998)

Designed and built during the era of the gas embargo, CAFE mandates, and tighter emissions, this engine family was designed to become Chevrolet's cost-effective, all-purpose "economy V8" engine line. Introduced in 1976 models, it had a displacement of 305 cu in (5.0 L). It was intended to fill the gap where the venerable 283 and 307 had been.

3.50 in bore family (1979–1982)

The 267 was introduced in 1979 for GM F-body (Camaro), G-bodies (Chevrolet Monte Carlo, El Camino, and Malibu Classic) and also used on GM B-body cars (Impala and Caprice models).

Major changes

The original design of the small block remained remarkably unchanged for its production run, which began in 1954 and ended, in passenger vehicles, in 2003. The engine is still being built today for many aftermarket applications, both to replace worn-out older engines and also by many builders as high-performance applications.

How long did the Street 302 last?

Is a 302 crankshaft bigger than a 302?
