OK, I think I have my cam picked out. I am leaning towards the TR 230/224 .575/.563 111 LSA. (or real close to that one anyway). But my question is on the heads. I know the AFR's are good, but which ones? The 225's? Here is a little info.......I am building the motor from a stock 2000 LS1 short block with stock lower internals. I am hoping to get 525hp+ to the crank. I want to keep the cr to about 10.5:1. It will be mated to a th400 with a 2500 stall. Application is an offroad truck (not street legal) that weighs 3000lbs. Will have custom headers. Custom intake with K&N.

Questions:

1. Is that cam too big for the stock pistons without cutting or replacing? Can I go bigger? Or if smaller then what cam?

2. I will want the LS6 intake, what size tb and injectors?

3. What size on the exhaust flanges and pipe? 2"?? then out at what size? 3.5"??

4. Fuel pump, how much gph?

5. What head specs should I look for?

6. With a stock harness and ecm, will the motor still run on stock programming long enough to get a good tune without any damage?

7. What should I expect to pay for a GOOD tune?

Please, if you have any advice or you think my set-up that I have so far is not good, please tell me. I am open to all options. My budget is high cause I want the good stuff, so keep that in mind, but I will always be willing to get a better deal and save a few bucks!! Thanks, Joey
