Hello everyone.

I am swapping my electronically controled carburated 305.
For a gen1 small black chevy crate motor.
My questions are
1.what/do
I need to block off or change in order to make this older style engine work with an overdrive transmission700R4
2.are thier any electronics i need to discard or reconfigure into the camaros wiring harness inorder to work properly.
I appreciate help ive gotton in the past.
The help with my replaced t-tops was so very helpful.
Please input from people who have done this as to not create confusion thankyou

 

I am in the middle of doing the same to an 84 bird, I will be following with interest. Thx

Your 305 is an older style SBC so everything swaps directly, keep the electronics and you can keep the overdrive with the lock up converter working. Other than adjusting the carb (nearly the same as adjusting ANY quadrajet) there is nothing that needs to be blocked or changed to put a 350 in there and be fully functioning.

 

Ok t ank you for the awnser.
I have an edelbrock 600 carb that will be on the new motor.
Will i be able to make this carburator work with the 350 in putting in
To be more clear its a 1988 goodwrench crate motor.
Im just confused because y friend speaks of this torque converter lockout plug for my trans,
But isnt thier a way i can keep the trans workig with out haveing to hit some stupid switch everytime i get past 50 mph?
And is thier a clean way of getting rid of my a/c wiring for the ac/ delete box im installing?

 

To clear any confusion the 350 is not a centerbolt style valve cover.
It is the old school style just made in 1988 as a crate motor.

 

I stress the edelbrock 600 because it is not an electronic controlled carb.
What should i do with those wires???
Again thankyou for help as you can see im a bit lost.

 

Why waste the time and modify anything to use an inferior carb? Is the current system not working correctly? If you keep the current carb you'll keep the functionality of everything WITHOUT modifying anything. All you'll have to do is probably rejet the carb and readjust idle screws. Which you'll probably need to do with the edelbrock carb too.

 

Well the current carburator is completely trashed.
As of now the car barely runs im assuming because if its age.
But your suggessting to just get a new electronic carb and not bother with the edelbrock?
I can see were this makes sense because then it would literally be plug and play.
Perhaps i can find a carb that runs well on craigslist.
Or maybe even completely refurbish mine.

 

But lets just say we were to use the 600.
Is it possible or not.
Or is that just a waste of time

 

Possible sure. Been done plenty of times....usually done by people who don't know how to repair the original system or afraid of it.... You could disconnect the ecm (ecm sensor wiring can be tucked away, cut out or de-pinned from connectors), change intake manifold to accomadate the square bore carb, change distributor to a non computer controlled type, run a new fuel line to reach the new location and link up the detent cable. The lock up converter feature can be retained using this...http://www.transdepot.net/product.as...FYcWHwodemkOGQ


Or fix the current quadrajet (really not as hard as it may seem, and they don't go bad nearly as often as it my seem) which has the added benefit of o2 sensor feedback. AND you don't have to hack anything.


Now if the original system is hacked up going and switching to a traditional style carb likely much easier. But then I'd still use a Qjet personally.

 

Ok cool,i see what your saying i think the original 85 way would be easier ill just rebuild the electronic carb.
I appreciate te help thankyou

 

I have a good working elec. q jet for sale. Removed from a 1984 z28 LG4 305. $100 + shipping http://atlanta.craigslist.org/wat/pts/5094297715.html

 

the stock carb is easy to rebuild: get a rebuild kit, a float, and a can of carb cleaner...

this allows you to just remove the old engine, put the new one in, and put all the stock stuff on it... it will look just like the 305, but run stronger. you also get a little experience actually fixing something instead of just throwing things away and starting over..


but if you are dead set on using the Edelbrock carb for whatever reason, you will also need to get an older non computer controlled distributor and make sure you hook the tv cable up to the carb properly and adjust it properly. then you can either just forget about the torque converter lockup wiring because at this point mpg's don't matter because you are already giving up a bunch compared to the quadrajet, but it's not that hard to move a few wires around to make it work... just google "700r4 torque converter lockup wiring diagram" and get to work.. some people say a 700r4 needs the lockup or it will self destruct, but i've got probably 20,000 miles on the trans in my car over the last 3 years with no lockup and it still works perfectly..

once you get it running without any of the electronic stuff, you can then really declutter things by taking out the ecm and the whole wiring harness that goes to it... you can also get rid of that spider's nest of vacuum hoses and switches on top of the engine, since none of that will do anything any more...
