GM SBC intake Manifold

I am building a 327 just because, and it will be a daily driver engine. The engine is a large Journal engine with a 4.00 bore. The heads are CI with 1.94s and 1.50's. It is a large chamber type heads so the compression will not be high. The engine has flat top pistons, a little cam in it as it had a nice rumble when shut down about 8 or 9 years ago ( I AM TOLD). The situation is that I now have an Aluminum GM 4 bbl. 1980-85 manifold (casting 14057053). Any one have anything to say about this manifold would be appreciated. I will attempt to stick with existing pistons if engine will clean up. If not will go .030 over bore flat tops. I would like to use this manifold, unless someone has some experience and can give me a good reason not to. I have not purchased a carburator yet but would like to go to E-brock , but that is very open at this point. HELP< HELP< Not sure which way to jump right now???

I'm not real sure how your finances are , but if it is truly going to be a 'daily driver' ,gas prices in the future might dictate a nice 2bbl intake manifold . I don't know anything about that intake you have , but if it's GM and aluminum - I'd guess it came off a corvette?? again , though -I don't know anything about it....
If you do go with an Edelbrock carb ( which I use ,myself ) , you'll give up gas mileage to a Quadrajet. Q-jets are harder to tune but better on mileage. ( so I'm told )
If you decide to use an Edelbrock intake , the RPM models are made for higher revving engines . The 'performer' model that I use works great for me.
Mine is also a daily drive(cough/workhorse) r.
Remember , all this is JMHO .
Good luck with your motor !

Well not quiet!

The book says the intake came off 80-85 305, 350, Pass, Camero, Trk. No Corvette. It seems to have lots of air space so should be a pretty good thing to use. It does have some sort of vacumme control gadget on it. I guess that could be blocked???
Had not heard that about the Q-jet, for fuel economy. I have a E-Brock on my 41 Chevy street rod now in the sorta final stages across the finish line. Will look into that. I am wanting to go for burning less gasoline but get a little hump when wanted. Will look into the Q-jet idea. Maybe try the junk yards.????

I just gave one away last weekend! It came off of a T/A , but Q-jets were stock on all kinds of GM cars and trucks. Shouldn't be hard to find , and rebuild kits are readily available , but from what I hear ,they are not all created equally . Some are more desireable than others , but I'm not sure why.

sbc intake

I have the same manifold on my 305 it is the stock manifold from a 1983 malibu cop car. It seems to work well I also had it on a 1971 350 with a small cam,headers and q-jet it worked good on that as well.

That type of posting on this board is in bad taste.

Intake and carb

That intake will work fine. The valve on it is an EGR valve, which is required on emission vehicles. You can easily make a block-off plate for the valve, but be sure to use the actual gasket because it will be a major exhaust leak if you don't..

If you can afford it, your best investment is a new carb. A lot of these easily found for 15-50 dollars can be up to 40 years old.

The newer junk gas has been famous for leaving a sludge tar residue that you might not be able to totally remove from the internal passages. So you could end up with junk after a lot of hard work and expensive kit, even though you did everything right.

Best of luck

The intake should be fine for a daily driver. If you go Q Jet, which I like, I prefer the Carter vice the Rochester. I also go for the pre electronic since they are simpler and more reliable. (The electronic was used to help meet the more stringent emission standards of La La land and later when the feds started raising the bar). Depending on your state emission standards, you probably will not have to meet all latest standards. One other thing, you will need valve covers that will allow you to fill the oil on one side and a breather on one side and a PC valve on the opposite. You will need either a vacuum port in the intake or at the base of the carb for the PC hookup.

To me, rebuilding and tuning the Q Jet is quite easy. The primaries are about as efficient as you can get on any carb and any tuning for performance is done on the secondaries. Fuel economy goes out the window fast when you call on the secondaries. I had a Carter Q jet on my 327 (300 HP version) with a Bowtie dual plane high rise, 3.36 rear and 700R4 that would get 21 mpg consistently as long as I stayed away from the secondaries. I changed this out for EFI which increased performance significantly and increase economy to 24 mpg. I will never go back.

Ignorance keeps me away from EFI

Thanks for the input and suggestion. I am after economy with out giving up total power. I just do not know what it requires to go to EFI??? That is the ONLY reason I have been sticking with carbs. Have you got any suggestions on how to get educated in this area. That increase in milage certainly sounds tempting.
