engine ID
I'm trying to figure out what engine my iroc has in it. Its a 5 speed car so it should be a 305. Now the guy I got if from says its a 350.I looked behind the AC compressor and found no numbers,then looked behind alternator..again nothing. I want to put new injectors but need to know 19's or 21's. Can I get the number off the computer..will that tell me?If it has nothing on it could I put 19's in even if he was right and it is a 350?I would rather error on the smaller side then flood the engine.Thanks!

Re: engine ID
Check the pass side stamp pad for a suffix or get a flashlight and peek on the bellhousing, drivers side, above oil filter. If it says 5.7 it's a 350
see where it says GM 5.7 here??
