Rocket 350 Vs Chevy 350

We have been asked a lot about which one is a more powerful and more dependable engine overall – the Rocket 350 vs Chevy 350. This is why we cut to the chase and look at the key differences between the two to help you decide.

Basically, the Rocket is known to have more power. But if we are talking about better performance builds, then we would recommend the Chevy 350. It comes with a 3.48 inch stroke and has a 4.000 inch bore. On the other hand, the Rocket 350 has a 3.385 inch stroke and a 4.057 inch bore. 

Furthermore, the Rocket 350 was produced from 1968 up to 1980. It is not at all similar to the Chevy 350. The Rocket has an output ranging from 160 up to 320 HP and there are cast-iron crankshafts combined with harmonic balancers. Moreover, there is an electronic port fuel injection system, which was found in the 1976 Cadillac Seville. 

The Rocket 350 has its Rocket name taken out in 1975 when it was dropped from the air cleaner decal. In terms of the blocks, these are definitely durable, reliable, and have ample power potential. 

Moreover, this motor replaced diesel in most trucks. It is also cheaper than when you replace the diesel. The Rocket also bolts up to your tranny as the diesel block is typically based on a conventional olds motor. The Chevy and Olds motors come with a different transmission, which means you would need to purchase adaptors that you can put to an old transmission on your Chevy. However, there is a price to pay for this.

You can also swap a total Rocket motor or transmission into your Chevy. There are different wiring requirements, plus the starter can be found on the opposite side. 

In case you prefer to drop a stock of the Rocket 350, you will not be out a huge amount of money by doing so. It is not very cheap but it is fairly reasonable. 

The Rocket 350 is also physically big. As for the intake manifolds, they weigh about 100 pounds while the Chevy is a bit smaller than 454.
