Quote: You guys have worked with the G3 aluminum. Any problems? I will be If I spend 4000.00 for a block that needs work or leaks like the W5. I would also like to find out if there is any truth the the mains seizing up. If it is true guys are holding on to this secret like it is gold. IMO this is hurting the Mopar camp. I know that there is R&D involved but save that for making power.
The main thing I'd stress is, avoid the "awesome price on an aluminum block with the wrong casting numbers on the internet" deal. If those are the ones you're referring to...I went over that issue with DW at Modern some time ago. I thought he planned on outing the seller, but maybe not. At any rate they're development pieces--AKA a science project. If somebody tried to build one and it blew up, it wouldn't surprise me at all. They are to be avoided.
On legitimate, Chrysler Engineering released parts I haven't had one single complaint from a customer.
In the limited amount of hands on work I've done with the aluminum G3 block I could not find anything that I would complain about. We went 146mph with it but I'm sure somebody will do better real soon.
