Hello, I'm new to the forum and looking for direction. I have a 2000 M6 Conv C5 since new. Looking for direction for prior posts or where to post for the following subjects:

1. LS1 mod to 427
- Camshaft selections to stay within CA smog limits
I'm running a 242/242 on 114 LSA and I wouldn't be surprised if that passes. However, I haven't smogged this combo yet.
- LS1edit baseline parameters for the 427
When you get the motor near the car I can help you. Need to know some particulars first.
- What aftermarket TB is recommended/size
Factory, ported, is fine.
- Can stock injectors be retained or need to be replaced with what?
No, you will need at least 30 lb'ers but I'd recommend larger.
- Pitfalls to the swap to be aware of
The power upsets the balance of the car and you can look forward to a major upgrade in clutch, tires, brakes and suspension - oh, better consider tubbing and 18x12 wheels with the 330x18's you'll be adding
- Does the engine exit the chassis from the top or bottom?
I've done it both ways but for me, the exiting the bottom was a more sanitatary swap.

I race a Pontiac GTO and a 230 inch SC Dragster, all Pontiac powered, so I'm ignorant to the LS1 and need some learn'in.

thanks
