427 carnage
Currently i'm going to have an LSX 427 built. I'm looking at getting a LSX block at the moment, and was told by a sponsor that some of the earlier blocks had some issues with them that were later corrected. I'm wondering with what production number are when the changes were implemented, and what exactly were the problems that were corrected. I hope someone knows!
Thanks,
Adrian

If you are considering something new, there are 2 great builders in michigan, both from the former W2W. PM sent. Good luck.

With all that is going on in Motown the HP gear is likely in low gear.
I also told the owner Tom Lieb at PRI as well and showed him some correctly made LSx cranks on display from Lunati and GM and Eagle etc. and he was certainly rather perplexed and they took the Billet crank they had on display down. The newer cranks they just released have a normal thrust now on them and they work fine besides initially using regular GM flywheel bolts instead of the oem metric GM LSx ones.
Most of the "high end" builders up there where you are from were using those billets a lot! I always knew how ignorant the builder was when I asked him about those SCAT billet cranks. I had a guy actually fix those right down here or I wouldn't use them. I have a bunch of pics from some of them before and after welding and fixing the rear thrust to be at least as wide as the bearing flange.

You are right, the thrust walls were maybe half the width of the bearing flange, ridiculous.

Thankfully the new ones they are doing are nice regular deals that work just great. I regularly and routinely use Callies, Eagle, SCAT, and Lunati, mostly but really never have trouble with any of them. Sometimes I have a very high end local crank guy trim them or straighten them a little but I have not had a real crank problem in 7 years now with any of the steel cranks that couldn't be fixed pretty easily besides those old SCAT deals. I paid about 150.00 to fix those or more.
