* Horsepower Varied: The 350 cubic inch (5.7 liter) engine was a very common option in 1988 Suburbans, but it was offered in several different configurations with varying horsepower output. This depended on:
* Carburetor vs. Fuel Injection: Carburetor versions typically had lower horsepower than fuel-injected models.
* Cam Profile: The camshaft affects how much air and fuel the engine intakes, influencing horsepower.
* Exhaust System: Performance exhaust systems can boost horsepower slightly.
* Factory Specs are Key: To find the exact horsepower, you'd need to know the specific engine code (often found on a sticker or tag under the hood) and consult factory specifications for that particular engine.
How to Find the Information:
1. Look for an Engine Code: Look for a code on a sticker or metal tag on the engine or firewall. It might be something like "L98" or "TBI" (for Throttle Body Injection).
2. Consult a 1988 Chevy Suburban Owner's Manual: If you have the original manual, it might list the horsepower for different engine configurations.
3. Use an Online Database: Websites like AutoZone or a reputable automotive resource may have online databases with factory specifications for older vehicles.
4. Contact a Chevy Dealer: A Chevy dealership might be able to provide information based on the vehicle's Vehicle Identification Number (VIN).
