This is what I'm basing this entire build on. 5.3's are out... i'll sell them to offset some of this cost...

I'm planning on reusing the stock intake manifold and an 85mm TB... see any problems there?

You can get the stroked 6.2L-418c.i. for how much more? and it's alot lighter than the iron block 408 n more cubes too!. Get you a tbss intake w/ a 90mm TB. If you go with the 418, get the stageII L92 heads with the L92 truck intake w/90mm TB.
