Crate Motor
Here's the thing. There is a guy selling a TTA Crate motor on Ebay, but the pistons don't look to be dished deep enough. The guy thinks it's a TTA motor, but I think it has the buick pistons in it. He said the pistons are 25535089 castings. Anyone know what that casting number is? They are in a crate motor SG1. I have a crate motor SG1 already but I am almost positive the one I have has the buick pistons in it. I think that many people just assume that the TTA's were the only thing to use the SG1 blocks. The stock buick casting number that I found on my original buick pistons didn't match the 25535089 either so I thought maybe buick used a different piston in the late crate motors. Anyone have any other ideas?
Thanks
