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.

[flash]

I dont know how to help you as all mine are carbureted small blocks but WELCOME .

I'm not familiar with the LS29, and google isn't helping.

If the car is going to be low, the 9" has a lower pinion, so it's easier to get your driveline angles set correctly than it would with a 12-bolt.

I'm not a fan of Hotchkis... their spring/shock combos work well, but I don't like their front end geometry or their rear bushings... they offer 2 types for the front, which is stock spindle (backward camber curve) or the B-body spindle, which corrects the camber curve, but messes up the steering geometry. The rear arms use poly bushings in all 8 points, which induces a roll-bind condition, making the car's balance very unpredictable. I'd recommend checking out either SC&C (www.scandc.com) or Detroit Speed & Engineering (www.detroitspeed.com)

I think what you may be referring to isn't an LS29 but an L29 as in the 1996-2000 Vortec Gen 6 454 and 502 style engines with the multiport fuel injection that uses a dry plenum. If this is what you are referring to, instead of using a truck setup do yourself a favor and find a Gen 6 454 marine fuel injection setup used and get the MEFI 4 computer and harness. It will be a total stand-alone system and all the wiring is already simplified for your application. There are guys out there like Blackbear tuning that can custom-tune the computer to optimize your combo. As far as fuel injection systems go- this is a cheap alternative to some of the Ram-Jet and Holley kits out there. I have seen the whole intake, injectors, wire harness, and computer go for around 700. Keep in mind you still need high pressure fuel injection line/hose and a pump that can support it. There are companies that make replacement Chevelle tanks with the sump and pump already installed.
