Default Build questions

This is the only section I feel that can really help me with this question.
I currently have a 96 Z28 A4 LT1 full BMR suspension, 12 bolt rearend w/4.10, stock trans with 3200 stall.
My plans is to build a LQ9/LS2 with forged rotating assembly for when my little LT1 dies.
So my question is how I go about the build. For cost reasons should I start with a LQ9 block and build it from the block up and then add all external parts? Or should I just buy a full LS2 swap out of a junk yard and then just add forged intervals, cam, and do head work?
So which is more cost efficient to buy a complete swap and add the performance parts I need? Or start from the block and build it inside out.

My goal is a 600-700hp N2O strip only car.

Thanks

If your going to do all of that, why not just buy a built Gen IV engine from one of the vendor / builders... Turnkey, MAST, Katech, etc..

2 reasons!

I don't believe in credit and I don't have a ton of money. I have 4k to start and I'll be able to invest about 500 a month in the build. Also try and save a little money by doing it myself.
Second reason is when it's all said and done I want to be able to say my hands put it together.

Good reasons..

what is the purpose or trpe of driving ? Drag, road, X-Cross or just a Daily Beater.. ? What is your goal on HP output ?

If Street and Drags. I'd go with the Bigger 6.0L or 6.2L with an Iron block. If weight is a concernt, the go with a LS2/3 or ?

L92 or LS7 heads flow really well. But there are many aftermarket one or vendor that will port them.

Its a stip car drag racing only.
