Dave Strickler's 1963 Z11

Here's what the Z11 looked like back in the Day.
This is a totally accurate recreation of Dave Strickler's Z11.

In 1962, Chevrolet was receiving increased pressure from the 421 cubic inch Super Duty Pontiacs in Super Stock and the lighter 413 MOPARs were rumored to be going out to 426 cubes for 1963. It was known that Ford would be issuing a 427 cubic inch version of their 406 as well. And everyone knew that both Pontiac and Ford would be offering "lightweight" versions of their cars for 1963. MOPAR was mum on the subject, but it didn't take a rocket scientist to recognize that they would add aluminum or fiberglass parts when the season started.

As such, Chevrolet decided to respond with a complete Regular Production Option "RPO" package for the new year. Thus, a special 427 cubic inch version of the W-Series 409 engine was developed. It would use a stroked version of the venerable 409 and be used in the 1963 Chevrolet Impala Sport Coupe. This would be available and ordered under Chevrolet RPO number "Z11".

More than just the new engine, it was part of a complete package created for drag racing only (Chevrolet had another engine in place for NASCAR - see below). The Z11 package would include aluminum engine pieces (not the block and heads) and lightweight body parts as well as a cowl-induction air intake system, along with the new 427 cubic inch engine.

The aluminum body parts were fabricated in Flint, MI at the facility now known as GM Flint Metal Center. Fifty of the RPO Z11 cars were produced at this Flint plant. No other run was planned.

Unlike the later second generation 427 (the Mark IV "canted valve" or "Rat") which is well known, the Z11 was based on the then current W-series 348-409 engine, with the 409's 4.3125" bore, but with a longer 3.95" stroke. Except for the stroke, the Z11 was not much different from the high performance 409 used in the successful 1962 S/S cars.

What was new was a high-rise two-piece aluminum intake manifold and dual Carter AFB carbs which fed a 13.5:1 compression ratio engine. This combo was able to produce an under-rated 430 hp and 575 lb·ft of torque (500 was more like it). GM documents show that 50 Z11 engines were built at the GM Tonawanda engine plant . . .

1967 Firebird 400 Test

1967 Pontiac Firebird 400 Road Test!

Car and Driver tested the new Pontiac Firebird in their March 1967 issue. The car was a Ram Air 400 Convertible. Though they just called it a "400". Being kind of ho hum when the authors first heard of any pony car intro, the testers came around quite quickly. They were impressed with the handling and performance and came away with a very favorable impression. "Firebird has an excellent chance of turning into a wholly distinctive member of the Detroit sporty-car set."

1969 Dodge 440 6-Pack Test 1969 Dodge Super Bee 440 Six Pack Test!

Car Life Magazine tested the Six Pack Super Bee in their July 1969 issue. The title of the test was "Pour it on Six-Pack" and pour it on it did - to a 13.8 @ 104. Sure, it was a quarter mile demon - but the testers were astounded by the car's excellent handling. They said two significant things: "With these times (1/4 mile) there isn't much justification for paying an extra $700 for the Hemi" and "six Pack Dodge - drag strip terror, Hemi equalizer, and 3800 lb 117" wheelbase slalom car".

1988 Saleen Mustang Test Modern Muscle - 1988 Saleen Mustang Test.

Many of you were part of the Muscle Car Era, and as such, you may have missed owning/driving an 80s-90s performance car. That would be a shame, because the revolution in performance that occurred then was actually larger and longer than that of the 60s - in fact it's still going on! But we digress -because what is important is the impact that Mustang made on the masses back then is no more apparent than this test. 14.60 @ 97 says it all . . .

Bill Elliot's 1965 Mustang Bill Elliot's 1965 Ford Mustang - Sweet and Swift!

This is the beautiful 1965 Mustang owned by Bill Elliott - yes, that Bill Elliott. We want to personally thank Bill and Cindy Elliott and Jordan Moss for the time and effort in helping us with this article. They are tops! Bill acquired this car a few years ago - it's a very early build Mustang, having been put together on June 29, 1964. Of course, this baby has been modified, not in the body, which looks very stock, but in the chassis and running gear . . .
