Even to bore? I just thought I saw some talk the the 6.2 left more meat on the cylinder walls after boring than the 6.5. Does the 6.2 blocks have the casting for the plate where the turbo oil return drain goes? Maybe 6.2 red blocks?Optimizer 6.5 is best metallurgy and castings.
But as you unfortunately learned, still none are bulletproof, so All of them benefit from chryo.
That is some mighty interesting information FT, thank You for posting that.Check the site below out has images of May 1999 enhanced block and pre-enhanced block.......my Burb came w/enhanced version.
I could make the same offer here as I made there.
If anyone is convinced I am wrong and think the May 99 block is all that, bring me some cash to have my May 99...
It all depends on the casting date. 506 is the current casting code for optimizers as well as back to 97 when the squirter blocks started. For the most part, 506's with sae bellhousing bolts are a losing gamble. 506's with metric bellhousing bolts are gen 2 blocks and improved. The rest breaks down to production date and where it was cast.So the 506 blocks are worth $2.00 per 100 lbs or a good boat anchor , correct? If I could get a 506 long block for 25.00 should I leave it alone or rebuild it?
Perhaps a custom billet block could be had for a reasonable price these days with all the new machining tech.......
