Insufficient data.

Most likely you've got a 305 TBI LO3. But, if the engine has been replaced, the intake info tells you nothing.

You need to get the casting number off of the block at least. The full number is above the bellhousing mount behind the driver side head. The last three digits are the most important, and often they are cast into the sides of the block in big numbers (easier to see once you get the car off the ground and crawl underneath than trying to read the numbers off of the back of the block with a mirror and flashlight in a cramped space).

The head casting numbers would be good to know as well. Those numbers are under the valve covers, so you have to pull the valve covers to find them.

 

yea i found the casting number on the back driver side u know GM ###########
but i only saw two rows of numbers and they were to short to be casting numbers
ill look under the motor and will find some numbers
