If your Camaro was a originally a 305 or 350 with a MAF,TPI system on it, it wouldn't be too hard to have bungs welded into the carb intake you have; then put the original TPI system on it. Not that you can't put TBI on that's do-able of course. These can be done using mostly OEM parts. The bungs can be had from several sources like Holley. The original MAF and throttle body can be used with an adapter plate and a little ingenuity.

you're better off just running a ported LT1 factory manifold.

thanx for tips etc

I am planning to run the gm performance lt1 carb intake I know I can do a tpi setup but my car came carb in 85/6 I want to use the adapter plate and use a tbi harness and throttle body ( as under the breather most would never know it was tbi tee hee) I think it would run decent and be rednek fuel injected. I have the intake off the lt1 etc but I have been down that road wanna try something new besides tbi is so easy to hook up and with minor mods it can haul *** I think I am only stumped on if the ecm will handle the lt1 cam that is the only problem I can see but seeing this was a b0body lt1 I think it was a slightly smaller cam than the f-body ALSO for all of you about to say the aluminum f-body lt1 was better you might wanna do some research the b-body made more torque and was only 15hp lower.hmmmmmmmmmm now that i have the lt1 carb intake it is up to 35% more torque and equal in hp JUST a tid bit PLUS I can run pump gas. Anyone who knows a place or thinks the ecm will be fine let me know.. This is going to be one of the cheapest builds I have done since you all helpeed me here on my chev 4x4 tbi mod.. Thanx again

if you use only one 2 barrel TBI unit, use one from a 454, the bores are a little bigger.

if you have the stock LT1 cam, it shouldn't be a problem.
with computer tuning, there are people running much bigger cams with fuel injection without a problem.

for best performance, you'll need an ECM that you can tune.
you have a few choices here.
1, get one of the aftermarket systems.
2, get a mega squirt.
3, use a factory TBI ECM and get the software to edit the bin and the hardware to burn chips.
4, get a EBL.

the aftermarket systems are viable, but if something happens to the ECM, you'll be down until you can get another one.
for the price, i feel the aftermarket systems are not a good deal.

with a mega squirt, you build it yourself so you should be able to trouble shoot and repair it.
im not sure about the MS 2, but the MS 1 wouldn't control ignition timing.

a with factory system, data logging is on the slow side unless you use an ECM from one of the later model pickups like a 94 or 95.
using a 94 or 95 TBI ECM would let you run an E-transmission like a 4L60E or a 4L80E.

the EBL, or Embedded Lockers is based on a factory GM ECM.
i've talked on-line to a number of people who have the EBL and most are quite happy with it.

with any computer tuning, there is a learning curve involved.
the info for learning computer tuning is available for free on the internet on a number of web sites.

you'll probably need an adjustable fuel pressure regulator.
even with computer tuning, the fuel pressure still needs to be within a certain range.
