Rebuilding my LS1 + add goodies? So, after my LS1 bit the dust, I've decided we're going to do a rebuild plus add some goodies. The car is still going to be a daily driver so I want it to be tame enough that I can drive it 45 minutes to work in rush hour, yet still have some get up and go when needed. Anyways, here's what I was suggested as starting place...
- Replace short block (big piece of metal knocked out of it just above the oil pan), so maybe stock or something bigger and then...
- 243 casting LS6 heads CNC'd port and open up to a 2.00"/1.60"
- Manley stainless steel valve with a three angle performance valve job back cut the valves
- Size the guides for the proper clearance and set the installed heights and surface the heads to 62cc for a 11:1 compression with your stock piston and the .045" Cometic head gaskets
- If you piston sticks out of the hole .010" like most LS1 engines then this will give you a .035" quench height which will be perfect
- Extreme Energy grind from Comp Cams - 230/236 Duration @ .050", .600"/.600" lift on a 112 LSA
- Gaskets, injectors (fast 36lbs), head bolts
- Push rods, should be the stock 7.4 but in a .080 wall for better strength.
Anyways... again this is JUST a GENERAL idea, more like a foundation to get the gears turning and start thinking about some different setups.

Any help? I'm trying to do as much research on my own as possible, but reading articles and product descriptions can only get me so far. Would love to get some first hand feedback with what does/doesn't work for my application.
