Why does a chevy 3.4 engine have more horsespower than an olds?

Question

For the same year - the same motor 3.4 a chevy (monte carlo) has more HP than the Olds counterpart - What is different on the 2 engines?

No, I mean - does it have a different cam or computer chip or higher compression, different fuel injection system - what can I do to raise the horsepower on my Olds 3.4 L to match the Chevy motor??

Answer 1

You don't say what year these cars are from. GM used to use a 3.4 DOHC in it's Lumina 2-doors, and possibly for a few years in the next style of monte. GM also has a regular OHV 3.4 built on the same orders as a 2.8 and 3.1 V6. The DOHC one is rated at 200 or 210 depending on what transmission is behind it, and the OHV engine is rated anywhere from 165 to 185 horsepower.

Answer 2

Here's the correct answer. Two engines of the same size (displacement) do not necessarily perform the same; this can be for a number of reasons. For starters, they might have different sized pistons, fuel injection systems, and/or transmissions. For example, a 5.0 engine in a Mustang and a 5.0 engine in a Ford pickup are technically the same size...but the Mustang is faster because it has been bored out for more horsepower, and has a higher-performance transmission and fuel delivery system. The truck isn't designed for speed, but rather for power for hauling, etc., so it's transmission is a different type geared for performing under a heavy load.

Also, the weight of the vehicle factors into it as well....a lighter vehicle will be faster than a heavier one.

Hope this info helped.

Answer 3

Different tuning from the factory. The Monte Carlo is usually a sportier car than an Oldsmobile.
