where i have to paste my engine pic???????
so it can be show

 

by posting some question about the rear end i just remeber that my
ratio is 3.8
now i think that's why i have a powerful acceleration
am i wrong???
btw how can i know the inch of my rear end???

 

definately doesn't look like a 289 or 302.
count how many bolts hold down the valve covers, small block has 6, big block is something else.

good luck

 

Here is how you can identify which rear end you have.

what do u mean by the valve cover?
is the chrome cover on the 2 side of the engine?
sorry i'm not so good in english but anyway thx for ur helpsss

 

Yes, the valve covers are those two long chrome pieces on each side of the top of the engine. Count the bolts that hold one of the valve covers down then get back to us.

 

doesnt look like a 351W to me, my engine is a 74 but still...

 

The 390's came with the '67 GT 390. The Engine number location is under the coil attachment bolt if it is a 390.

 

Just found the pictures. That is definately an "FE" big block. Most likely a 390 but it could be just about any displacement in the FE engine family. Have fun, they are torque monsters. Quick question, you mentioned that the VIN indicated that the car came with a 289. Did you take the VIN from the door data plate or the actual registration documents?

 

Dang he beat me to it. Yeah, Thats an FE engine. You can tell by looking at the water pump. It doesn't mount like a small block does.
