<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Kurt S</div><div class="ubbcode-body">From http://www.camaros.org/drivetrain.shtml#BlockCast - The 3959512 SB casting (not to be confused with the 3963512 427 casting) was mainly used for warranty / service blocks, though it did have very limited production usage in 69 engines. It is a 4&quot; bore block, thus could have 302, 327, or 350 applications.

Yup, the block is the same, but the pistons and crank are unique per displacement.
Could be a 66 warranty block, but doubtful on the 65 unless he just bought it as a service part. </div></div>

Yes I made a mistake on my original post when I said 1965 as he has a 1966 Corvette. I am a Chevelle Guy that does not know much about Corvette's LOL, Thanks Kurt [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
