i have an 85 camaro. i was told it is an iroc. it has a tpi engine in it now, i am trying to figure out if it is an iroc. it looks to be an engine swap car. how do i find out what engine i have? 305 or 350/ what the engine is from? it is a canadian car. if you can help me that would be great.

 

Go to Compnine.com, click on the VIN Decoder/RPO Finder link and enter your VIN. As they have Canadian records, if your Camaro is Canadian, it will show a list of RPO codes tied to your specific VIN. Look for B4Z RPO code if it's an Iroc.

 

Also, you can check the tire placard in the drivers door jam, assuming it's still there look for 245/50VR16 tires. All Iroc's in 1985 had 16" wheels.

 

it told me it could not find my vin. i will keep looking. thanks

 

Make sure you didn't enter the ones as Ls or vise versa send me a pm and let me look at a picture of your vin#. I'll give it a shot.

 

Hold out for a bit. It appears they're having an issue as I checked a known VIN that recently worked and it's not currently working either. I'd wait for a while (day or two) and try again.

 

You don't need to run your VIN to see what motor you have. If it's a swapped motor, your VIN will tell you nothing.

You need to pull the casting code off of the block and run it at mortec.com or similar site.

Depending on the year of your block, the numbers you need will be stamped right in front of the passenger head above the water pump, or behind the head on the driver rear of the block. There are also identification numbers cast right into the block that can help you identify it.

There's also the option of pulling the valve cover and checking the cylinder head casting number. There's no guarantee that the block is still wearing it's original heads, but it's at least more pieces of the puzzle.

As for finding out what motor your car came with originally, that's as simple as looking at the 8th digit of your VIN. An "F" indicates that your car came with the LB9 305 TPI. A "G" or "H" identifies the L69 305 and LG4 305 respectively. An "S" indicates the 2.8 v6. I can't remember what the VIN code for an iron duke is.

 

i don't have my vin with me right now. i will check the cast no. on the block and heads.

 

By the way, the issue on Compnine.com was resolved and you should be able to run your VIN and find out what the car originally was, which was part of your question.
