when i bought my car i was told it had a "Rebuilt" motor in it... Implying it was the stock 305 just rebuilt... I believe its not... Or if it is the stock TBI and heads aren't on my car. I'm assuming at least...Reason why i think that is because on the vaccum diagrams they show 4 things coming out of the front of the TBI.. Mine has 3... Then the heads aren't center bolt valve covers like they should be... They go along the edge.. Although i have edelebrock valve covers not stock.

so i need help identifying my stuff...

Th numbers i could find( I know on the back of the head apparently there is a number... couldn't find it though)

L195( or at least thats how it looked to me) Was on the backside of the engine about the tranny. Near the distributor area.

Then on the intake it says W4 Gm 14102182

Throttle body says 17087101 then under that it says 3107 JRA

Can anyone help me out in identifying my things if that will get you there.... If not can someone point me in the direction to other places to look on the motor.... Motors in the car so i can't like disassemble anything to find it.



Motors supposed to be a 305 TBI.

 

Check on the block itself on the back side of the block (driver's side). There are numbers there. For that year it should be stamped 5.0L or 5.7L. The heads are pre'86 if they have do not have the valve cover bolts in the center.

 

yeah it says 5.0...I know the heads are pre 86 but im trying to find if the rest of the motor is to or not.

 

Look for the seven or eight digit numbers on the block (i.e. 10153558 or 3970020).

 

Look for the stamped numbers on the pad in front of the passenger side head. Those will tell you more about the engine.

You can also pull a rocker cover off and get the casting number for the head.

 

Hi I have the same problem when I bought my 89 Camaro RS, the person I bought it from was uynsure when, but claimed the person he had bought it from had the engine rebuilt, it runs great but after realizing thr carfax had said it had over 200Kmi I knew I was in trouble. How did you find out where to look on the 305 tbi motor? My motor is almost impossible to get behind far enough to read anything, where can I find the serial number or casting date to put this question to rest? All I found was the w4 14102182 which I searched and led me to this page. Thanks!
