What year and cubic inch is this engine. Has #5A heads .

 

This carb was on the engine as well no clue as to size or year. Carter quadra jet.

 

Olds 307, an 80's, I assume an electronic carburetor.

 

Nope a Carter quadra jet. My bad😂

 

Looks like a 1980 Chevrolet Qjet, is it side inlet?

 

I would have to check. I don't remember. And I will take a complete picture of this carb tomorrow.

 

Carb is 1980 Chevy / GMC truck.

 

Thanks!😊 Now if I can find out about the block. I did a search and found nothing. Maybe a restamp.

 

3AMxxxxxx is a 1980 VIN derivative. The "A" indicates the 1980 model year, "M" naturally is Lansing. Olds made 260, 307, and 350 blocks in the 1980 model year. We need a photo of the block casting number to know which it is. The 5A heads suggest a 307, but of course they may not be original to the block.

 

says 3161-5A Joe

 

307. 1980 was the first year.

 

 

Thanks Joe.
