Installation of ZZ4 Crate Engine in C3 Corvette After 30 years and 75, miles, my original L engine was still very dependable and running solid. I also wanted to keep my numbers matching engine so that the car can be restored back to original at some point. After many hours of research, I decided to purchase a new ZZ4 crate engine from GM with specs as follows: GM part number – ZZ4 Crate Engine, Generation I long block, includes 4 bolt main caps, nodular cast iron crank with one piece rear seal, Passenger side dipstick and center bolt valve covers. Preparing the ZZ4 engine for installation in a C3 is not a major deal but there are some things of which you need to be aware and I will discuss these in this documentary. One of the things that you will want to know is ‘what parts from my old engine will fit on the new one? The ZZ4 comes with a long water pump which of course is not correct for a C3. The timing cover on the ZZ4 is a composite material and one of the bolts retaining it must have the head ground down to clear the back of your original pump.

Low RPM turn on and charge Fits factory applications Low and high current applications Multiple finishes available But now that people are driving their classic cars more often, and upgrading them to be more drivable, they are also adding more electrical components so that driving them is more enjoyable. Some cars also have an air suspension system, meaning the compressor needs to keep that air tank full — and that draws on the electrical system more than ever was intended.

Upgrades to digital ignition boxes and alarm systems also add to the amount of wiring that is added to a vehicle; people are also adding electric cooling fans to replace the mechanical fan. So how do you upgrade an electrical system that was never designed for all of these accessories?

For the warning light, a lamp is wired in series with a switched voltage source. During normal operation the lamp stays off. If the regulator is damaged, the 1 terminal provides ground, and the warning lamp will light. This terminal is also active on 1 wire regulator equipped 10SI alternators. Marked with a “2” on the case This terminal is used to excite the 10SI into operation. For simplicity you can connect the 2 connector pigtail directly to the “batt” terminal on the alternator.

Tech How do you hook up a 1-wire alternator? What do you do when the stock alternator was originally externally regulated? The only thing you need to hook up on a one-wire alternator is a charge wire from the terminal on the alternator to the positive terminal on the battery or any positive battery source. The external regulator can either be totally dismantled from the firewall or left in place.

If left in place, be sure to disconnect the wiring harness from the regulator.

Replacing and Relocating the Alternator with a CS A recent replacement of the front crankshaft seal motivated me to start a project that I have planned but have been postponing for some time. Replacing the anemic original Jaguar alternator with a modern Unit. While there are a number of alternators that will physically fit in the air pump location, I decided to relocate the alternator to the air pump location and replace it with a Delco CS alternator for the following reasons: GM made hundreds of thousands on these alternators from to Some independent alternator rebuilders have expressed some concern that this unit suffered from overheating and had a somewhat high failure rate of the rear bearings.

For me this was not an issue. When one considers the vast number of these alternators, the failure rate was well within the norm. Alternator configurations generally can be classified in three main categories: This unit uses a special voltage regulator that doesn’t need an ignition wire to activate it. The voltage regulator contains circuitry that uses the residual magnetism in the alternators fields to decide when to turn the alternator on. The regulator does this by sensing the RPM the alternator is turning.

Essentially, when the alternator gets to a pre-determined RPM, the voltage regulator turns it on.

These alternators have proven to be one of the most reliable products we sell. There are many different companies that sell a similar unit, and rest assured, most are not to be compared to ours. We have been selling this same unit for over 5 years, and take notice of our sell rate. The return rate on these alternators is near zero. The performance is excellent. The fit is spot on. We have had the opportunity to sell different brands that cost less, but have found them not to be comparable to this unit.

Think twice when you see a lower priced unit on the market. Quality and performance make our unit a far better value, in our opinion. This alternator may be used on OE GM applications that use a three wire hook up or as a one wire hook up for applications that do not use the conventional hook up. The 10SI internal regulator alt came into use around It was the first year for the internal voltage regulator.

Instructions Light Weight – High Amps With the accessories many of today’s race cars have such as electric fuel pumps, fans, nitrous solenoids, water pumps and hi-amp electronic ignition boxes, generating adequate current is essential for maintaining the voltage you need and to avoid charging your battery every round. This GM style alternator has a amp punch to keep up with your electrical accessories and it looks great in your engine compartment.

Single wire hookup means less electrical headaches, it’s simple to hookup and get running fast. This design uses a self exciting field which means when it spins at a sufficient RPM, the alternator will start charging. When the engine stops rotating, it turns itself off. Keep in mind that the engine has to be turning around RPM in order to spin the alternator at RPM in order to get it to start charging.

Just start the engine and “blip” the throttle in order to get the alternator to turn on. You don’t have to keep the RPM up, once the alternator is energized with a quick blip you can let the engine idle back down. If the max rpm is exceeded it can cause damage to the internal armature and cause a failure. Please keep this in mind when choosing your crank pulley size.

Note that most street pulleys are ratio, which for a typical racing engine can spin a alternator too fast. Do not over tighten the belt! Install the belt and adjust so that there is approximately 1″ free play in the belt when measured half way between the pulleys. Don’t forget to tighten all bolts.
