I bought a 305 from a firebird and me being the idiot i didnt check the vin or see if the car was a mass air flow or speed density. The casting number is 14093627. Alot of people tell me its a 87' to 89' and i know that mainly cause the motor has roller lifters and roller cam. The back of the computer says its an 87 to 89. So i know it must be a mass air flow but I really want to know What EXACT year the motor is. Why u ask cause im tired of people asking me what motor do u have in the car? my response oh dont know and they look at me like im an idiot so please help. Hopefully u guys have your casting boooks.

On the back of the block where the bell housing bolts, up there will be a date code telling you when the engine was cast. It will have one of these letters (A-L) which will reference a month. Next it will have one of these numbers (1-31) which stands for a day during a month, and then it will have one of these numbers (0-9) which stands for the year. You have to know what decade the engine was built in.

Example D 12 7 = April 12 1987 was the casting date of my example.

Hope this helps

there is also another way of going about this.are the fuel rails on the motor?if they are there will be a number on the fuel rail it's self.it's either 6,7,or 8 numbers long.if you can e-mail me those numbers i can hind out for sure(i have that info here some where in my apartment)
