I've been talking/thinking about going LS3 for a while now. I bit the bullet and purchased the GM LS3 495 hp crate engine. Should be here in a couple of days.

Plan is to convert my LT1 style T56 to LS style. I'm still researching clutches, accessory drives, oil pans, etc. but I'm pretty close on all those. Lots of parts to buy, list is long.
