Port fuel injection meets a small-block classic.

GM Performance Parts has just what you need to put a modern new twist on your favorite classic hot rod with our amazing Ram Jet 350 crate engine. GM offered the Ram Jet fuel injection system on a variety of models in the late-1950s through the mid-1960s, but the Ram Jet has never looked as good as this!

Evoking the nostalgic look of the early fuel injection systems, the Ram Jet 350 has a styled intake plenum that actually leads to a modern day fuel injection system. Instead of a mechanical injection system, the Ram Jet 350 is fed by a state-of-the-art, electronically controlled port fuel injection system. Developed by GM to the same standards as production vehicle systems, the Ram Jet 350 delivers exceptional throttle response and performance. This is made possible by the sophisticated, latest-generation MEFI 4 controller, which has improved electronics and closed loop capability (compared with the previous MEFI 3 system) for great all-around drivability.

A venerable 350 cubic-inch small-block combination anchors the Ram Jet 350. It is designed for long-lasting durability and pump gas compatibility, with Vortec cylinder heads, a hydraulic roller camshaft, and 9.4:1 compression.

GM Performance Parts delivers the engine with the necessary wiring harness and detailed instructions. It can be installed on any 1977-or-earlier vehicle originally equipped with a carburetor. Now there's no reason you can't dump those old carbs and get fuel injected!

New for 2010, our best-selling crate engine is offered in a new Deluxe package that includes an intake manifold and chrome dress-up kit. The manifold is a high-flow aluminum intake*, along with the gaskets and installation hardware. The chrome dress-up parts add a bright, finishing touch to the 350/290 HP.

It's easy to understand why this economical crate engine is so popular. It features four-bolt mains for strength and it's filled with premium parts, including a smooth hydraulic camshaft and durable aluminum pistons that deliver an 8.5:1 compression ratio, making it a great, time-saving alternative to rebuilding a tired, two-bolt-main core engine.

GMPP also has all the parts you need to get your 350/290 HP engine running in your project vehicle, from the starter and distributor to the plug wires and more. And if you want even more power, our high-performance cylinder heads will take this stout small-block to the next level.


*GMPP recommends Holley 670-cfm carburetor P/N 19170092 for use with the 350/290

The best value crate engine in the GM Performance Parts lineup!

The 350/290 HP is the most popular GM Performance Parts crate engine because no one can deliver such performance for this kind of value. GM Performance Parts believes that everyone should be able to afford a high quality, high performance GM V-8 without going broke. The 350/290 is an answer to those car crafters who demand maximum return on their money. However, just because it's affordable, don't think that it's a stone. The 350/290 delivers 290 hp @ 5100 rpm and a solid 326 lb.-ft. of torque at 3750 rpm. With those kinds of numbers, it's the perfect replacement engine for the millions of GM vehicles that shipped with a small-block. Got a tired, old project car that needs a lift? This is the crate engine for you.

We've also loaded the 350/290 with a four-bolt main bearing block, aluminum pistons, and a hydraulic camshaft. The cast iron cylinder heads are designed to be extremely durable while still providing good airflow through the engine.

The 350/290 will ship to you as a Base-level long block. Add an intake manifold, carburetor, ignition system, starter, balancer, and water pump, and you'll be ready to hit the road with a fresh new motor. All of these parts are available from GM Performance Parts, and with its low price, you'll have no problem finishing off the 350/290 in style.
