Ok guys I need some good advice or opinions.

I am rebuilding my ld9. I have already bought the secret cams, 1mm over size valves, manta part stiffened sports springs, and polished my exhaust and intake ports. I didn't go crazy on the intake but I did get the exhaust very smooth. I am going to use eagle rods, and wiesco pistons 40 over 10.5-1. I am sending my balance shaft assembly to JBO to get the neutral balance shafts. What do you guy's know of lightening the crank? I have been told it can cause some balance issues and where bearings out faster. Any ideas of where I can get my rev limiter changed? I would like to go to about 7500 rpm's. Anyways if there is something here that I forgot or that anyone thinks would be a good idea please let me know.

oh I forgot to add that I do not want to use a 2.3 oil pump. I would like to keep most of my torq in the lower rpm range where it is now so should I stay with the orignial cams or shoudl I use my secret cams? How much larger throttle body should I use? Or sould I use a bigger one at all? I have a header from pacer, and custome exhouast already. under drive pully, and cia. Sorry for all the questions but any help would be appreciated.
