How do i tell if i have a 331 or a 306?
I just recived a shortblock that i purchased. On the reciept it says that i ordered a 306. I opened the package and started checking out the motor. Its totaly wrapped in plastic and on the side there is a tagthat says that it is a 331 stroker. do you think they sent the wrong shortblock? or is the labeling of the block wrong? how do i tell the difference between the two? If they sent me a 331 instead of a 306 im not complaining.

Ok, how does that compare to the block specs your were expecting?
Oh and, you need to get EXACT measurements not "around 4 inches" because I doubt there's a huge difference between a 306 & a 331

Yeah, the only difference is the crank, rods, and pistons. 331 has 3.25" stroke, longer rods (5.4" vs 5.09"), and piston pins mounted higher in the piston.
