The head numbers only work if they are the original heads for that engine. I should have pointed that out. : P

 

I couldnt find the number...

how easy would it be to see if it is still inside the car?

 

Not very. If you know if the heads are original you could check the head numbers. That would be the easiest. There's a good chance that the block number's all covered in grease and dirt and isn't visible...

 

Okay, I'm getting aggravated, If the sport coupe code is Q, and the sport coupe is not a Z28, as you say, then what is the code for the Z28? Don't tell me that it's the S code because that was the code for the Type LT and later on the Berlinetta. and GM lists no other codes. 1Q87 was the only prefix I have ever seen on all the second gen Z28's I've ever looked at, including the 79 Z28 I own. Just so you know I also own a 79 Berlinetta and the prefix on that car is 1S87. The RS and Z28 are cosidered sport coupes and carry the Q code. If you motor is a stock and untouched 350 then you should find either 186, 624, or maybe 882 heads bolted on it. In 79 the fifth charactor was the engine code L was the 350 and G was the 305 which usually came with the 2bbl carb. alot of guys did 4 bbl converstions to these motors.

 

Well Mine has got a 4bbl on it... I know that doesn't mean much so Ill go check out the VIN code a little later I'll check the VIN later today. Lets hope I get an L!!

 

Checked it out... seems like it is only a 305 how disappointing...

 

so what does it need to say to be a Z-28 im kind of confused lol.

 

I think it is somewhere on the data plate, but, I can't find much info on it. My Z and my RS both have the 1Q87 prefix but only the Z has the black trim and headlight bezels, it also has a thicker front sway bar and came with the five spoke steel rims wraped in 225/70R15's.
