Alright guys maybe I'm just nuts are a little confused but I do need some help here.

I have depending on what I decide to stick with an Edelbrock 1406 or 1407 (600cfm, 750cfm) carb. What does it take to hook up to a 90 Camaro that was tbi and is automatic. Is there any special brackets or levers I need to get our does everything hook up as is?

Thanks for the help I really appreciate it!

You'll need a throttle valve (often mistakenly called "kick down") geometry corrector bracket for Edelbrock carb.

Thanks Five7. So I don't need a throttle bracket just a geometry corrector?
The tbi throttle cable will hook straight up to the Carb?

Thanks again.

You might need a stud that mimics the TBI attach stud, but reports are the TBI cable will work (no personal experience).

Re: Hooking up a carb
When I did mine, I got a nice strong Edelbrock chrome cable bracket - it just seemed like I couldn't get the TBI cable bracket to work on my Edelbrock Performer RPM intake - but if you're keeping the stock intake, then it might work ok.

Make sure you get the geometry corrector - it's critical to the tranny (if automatic).

You'll also need a vac advanced HEI dist., and a way to lock the torque converter if auto tranny.

Thanks for the replies!
I have a edelbrock Torker II manifold does anyone know if the cable will work on this?
I do have a non cc HEI. I plan on leaving the ECM hooked up to allow the fuel pump to prime will this mean the car will still go into torque lock up with the ecm still connected are will I still need to do the TCC switch or buy a kit?
Thanks again guys!

The only functions of which I'm aware that the ECM will continue to provide are fuel pump operation and VATS. Other than that, it won't have the information it needs to provide things like TCC lock-up. So, yes, you still need to provide some other means of lock-up.

Any particular reason for that particular intake manifold? It's about the worst choice out there - doesn't do anything well.

Really?
I've never heard any thing negative about it. In fact my father ran it on is 377 Stroked Buick for years when he was young and street racing.
Whats a better intake manifold option?

600 cfm edelbrock carb
Comp Cam XE242 - 224/230 at .05 duration .477/4.80 lift and 110 LSA
416 (305 HO heads)
CR around 10.1

Will not go beyond 5800rpms.

Thanks again.

I have an 88 GTA that I converted from TPI to carb using an edelbrock 1405, and I used a stock TBI throttle cable from a 91 Camaro, and so far, all appears to be working just fine.

The Torker intakes are single plane. The original Torker wasn't too bad for what it was, but the Torker II takes the worst of both worlds and combines them into one unit. Powerband 2500-6500 means you'd better have a torque converter that stalls above 2500 RPMs. Gives up the lower RPMs with no gain in the higher RPMs. Not good for cruising.

Your dad probably had a Torker, not a Torker II.

Are you sure about that cam grind #?

The Performer EPS is good from idle to 5500 RPMs. The Performer RPM is good from 1500-6500 RPMs. On a 350, the Performer RPM would be the better choice.

I also would recommend a different carb, but if you like Edelbrocks, go for it. A 600 on a 350 reving to 5800 with a single plane intake is marginal, if you do go with the dual-plane Performer RPM, you'll want at least a 650.

Re: Hooking up a carb
Sorry about that the cam's part number 242 or as comp cam has it 12-242-2
the actual cam grind is xe268h.

Would a 750cfm edelbrock be a better choice in that regard then?
The reason I say edelbrock is because I have a 750 I bought and rebuilt but was told it would be to big by a mustang guy (5.0 Fox) who has an edelbrock 600 he wanted to trade me for.

Performer rpm you said is 1500 rpms to 6500. With me going to 5800rpms wouldn't the Perfromer EPS be a better chocie being a idle to 5500 as I only lose out on the last 300 of my revs which goes by so fast anyways?

Just curious. Thanks.

XE268H, that makes more sense.

The 750 would be fine. Not quite as crisp off-idle, but better overall power.

The RPM would be the better of the three intakes. You won't notice the 500 RPMs you'd "give up" on the low end if you have a converter that stalls above 1500, but you would notice the 300 RPMs you'd give up on the top end with the Performer. You actually lose power from about 4500 RPMs up (I think - been a while since I saw that article) with a Performer vs. Performer RPM.
