I have a 1969 Mustang. How do i know for sure what type of engine it has. I have been told it is a 351 Windsor. Is there a part number some where on the block to prove this is it? Also Im not sure if it is the original engie although it does have an original blue ford intake manifold.

Thanks

I'm sure there is somewhere under all that muck. But;
If the valve cover has 6 screws, it is 'small block' 302 or 351. 8 means 351 cleveland. I'm sure more advice will follow...

 

thats a cool little thing to know, i never knew that.

 

not very many came with 351w. send us pics. actually tell us your firing order.

 

Firing Order:

15426378 = 302
13726548 = 351

 

Mine came with a 351W.....to bad the old driver blew it up.

 

Same here, on both accounts, except I am the old driver too. Long story...

 

5 valve cover bolts is an FE

 

Here is a pic of the motor, it's pretty dirty.
