273 Commando Southern California / Los Angeles Area Machine Shop / Engine Builders

@Bossanova5 I have never used them myself for engine building, but I have heard good things about L&R Engines.

Here's their website: L & R Engines

The only work they've done for me was resurface a flywheel. This one guy that has a white 'Cuda with a Hemi that is usually in the local shows (Fall/Spring Fling and Mopars in May) recommended them to me.
