LS29 or?

[Oldiron]

Hi,

I'm a newbie here so please cut me some slack... I have a POS '67 Chevelle that I am now in the position to finish it most any way I want. The delimma here is that I want to put a big block in it and currently have a 454 and a T-400 for it sitting in the garage. The build will be for a driver, kind of industrial, clean... My gearhead neighbor has me mostly convinced I should go with fuel injection which is where my quandry begins:

Should I go with the LS29 (which is the most recent BB GM I can find) or build the 454 GEN? that I already own. I don't see aftermarket parts for the LS29 that I can identify as a neophyte...should I steer clear of the LS29 and build what I have and use FAST, Edelbrock, etc., FI for the engine I own? I want to end up with ~650hp at the engine and remain on pump gas...10:1 or less, if possible....

The second question is on the tranny: I think I've convinced myself that the T-400 gets sold in exchange for a 6 speed manual...I''m planning on Hotchkiss suspension and looking to do corner carving instead of straight-line...who makes the best 6 speed manual...if there's a choice?

Coil-overs or?

It has a 10-bolt. S90, 12-bolt, 9" Ford, or?

Does anyone have experience on rack and pinion on a '67 Chevelle?

I realize these are a lot of questions but I need a little help and push in the right direction.
