I'm looking to buy a firebird off an aquantance, and he swears a LS1 motor was p[ut into his firebird. I want to know if there are any defining marks on the LS1's that will prove wheather it is or not.

have you seen the motor, or a pic of it?what year is it?
[Reply]

The LS1 has a pretty distinctive intake on it. The runners are set back like halfway in the engine bay and appear to run horizontally across the top like an arch. I dont have any pics, but someone like Luos or Formula will. The throttle bosy and valve covers look different too...basically, you cant mistake it for an LT1 or L98.

Wow, how long have you had the car, and been working on it?

Just over 4 years for both.

Sorry, the only way I can feel better about myself is to put others down. I need a new engine.
