I am starting the assembly of an all aluminum 510" street engine that might be of interest to some. It is going in a 69 Firebird. It came in about a year ago. Here is a link to the original thread started by the guy working on the car.

This engine had many issues, from stripped out main cap side bolts because the heli-coils were in crooked, to cracks in the main web, to main caps that were serrated on the sides so they would dig into the register of the block, to cylinder sleeves that were bored .040" off center. Then there was the crooked heli-coil in the deck for one of the head bolts, and the deck that was .060" short! Oh, and don't let me forget about the cement type substance they filled one side of the block with, and the epoxy crud they filled the other side with. The pin bushings had very little clearance, and the rod big end was small, and out of round. Many months later, and lots of work, it's finally ready to build. This engine will be dynoed in the next couple weeks.

Here is a shot of the crud in the rear oil gallery. Remember, this engine was sold as a ready to run short block.



A close up of it.



Here you can see the offset in the boring of these sleeves.



Here are the sleeves after pulling them out.



And the block without them.
