Engine upgrades are definitely not new territory for Lowriders. Since the beginning, we’ve searched for ways to dress up every aspect of our classic rides, and under the hood is no exception. When it comes to chrome engine parts, we are the kings of bling, as we bolt up as much as we can to keep our engines looking good, cool and our performance top notch. The first engine upgrade on most of our respective lists is to modify the carburetor and intake. This key upgrade can not only improve the look of your engine compartment in a very short time, it can also improve the performance and engine efficiency of your Lowrider. We decided to go back to basics in this month’s column and install a new intake on a 350 GM Performance crate motor. This install took only a few of hours, as we used the Edelbrock Performer Air-gap Endura-shine manifold. This award-winning design incorporates the same race-winning technology with a show quality finish that’s been widely used on a variety of Edelbrock intakes. The air-gap design features an open air space that separates the runners from the hot engine oil, resulting in a cooler, denser charge for more power. RPM Air-Gap manifolds are modeled after Performer RPM intakes for high performance street power from 1500-to-6500 rpm, and the new Performer Air-Gap manifolds are ideal for street performance from idle-to-5500 rpm. Now follow along, as we install this Edelbrock intake and carb combination on this crate small block 350.
1. Edelbrock’s air gap intake and 700 cfm carburetor combination were perfect for this 400hp small-block engine.
2. This 350 engine was ready to be prepared for some horsepower.
3. With the intake off the engine, we took advantage and added as much as we could outside of the car, which included a thermostat installation to keep the engine running cool.
4. Thermostat housing was bolted on and will serve as a handle when it’s time to put in the intake.
5. We installed the ARP carburetor studs outside, making the install easier as we proceeded with the build.
6. The edges of the block were cleaned up to allow a good bond between the silicone and intake manifold.
7. The gaskets were test-fitted to make sure that they were the correct models.
8. The engine was ready for the intake to be bolted on.
9. Sal carefully installed the Edelbrock RPM intake.
10. The intake lined up perfectly and was ready to be bolted on.
11. Sal started off by bolting down the intake from the rear, using a cross pattern to bolt down the air gap intake.
12. Since we knew that this car would be a cruiser, we used an off road carb combination.
13. We pulled off the stock plugs in order to drill and tap them.
14. These fittings will ensure that we have no air leaks.
15. The carb was attached to the intake so that we could plumb the stainless steel Classic Tube lines.
16. After a few attempts, the hard lines were completed and the final touches were given to finish up the engine.
17. This Edelbrock intake and carb complemented the engine perfectly.
