I got the id number off my trans am's engine, supposedly a swap. the last three letters which are supposed to what tells you what kind of engine it is. well mine reads DDU but every website I've visited doesn't have an engine with this designation. Could anyone help me with this?

 

look on the back of the engine block behind the drivers side head and get the casting #'s

 

Thanks general. I appreciate the help, but i was hoping there would be an easier way to do it.

 

that is about the easiest way i know..LOL...just get a long screwdriver and clean that area off and take a drop light or flashlight and look down the back of the head on the drivers side and get those numbers they arent that hard to get just takes a little time and some patience ...and the ability to lay accross the engine for a prolonged amount of time.....LMAO

 

are you sure those letters are correct DDU?????

i found these codes at http://www.nastyz28.com/sbchevy/spcode4.html

heres another site with the engine suffix codes and it doesnt list anything at all like that ????

http://www.chevy-camaro.com/SBCblock.asp

 

Hence my predicament

 

yeah i can see..LOL

id say you need to get the casting #'s off the back of the block

 

i've learned what the engine is. I thought my engine id read DDU, when i just looked at the list of engine ids i noticed an engines specs that cuaght my attention. it was DDD. ITS THE STOCK ENGINE FOR AN 82 TRANS AM!!!

 

doesnt sound like its a swap then ????

did someone tell you it was when you bought it ???

if so thats just not right...

 

IT'S GROUNDS FOR A LAWSUIT ACTUALLY.

 

THEGENERAL's list says it's an '83. Or, is that list not complete, perhaps?

If it's an '83 engine, then technically it was "swapped" (although "changed" would be what we'd call it here).

Rather than grounds for a lawsuit, it's more like another lesson in life's school of hard knocks called "buyer beware".

 

 

yup it was definatly swapped in to the car from the looks of it

i didnt realize that his was an 82 and that the engine suffix code was a 83

man my eyesite must be going now....LOL

 

It's midnight. Hit the hay already...

 

im on my way as soon as i finish my last cup o java.... you???
LOL
