Intake Manifold Question ND ?
I have a 65 sb styleside 352 3 on the tree I have an intake manifold gasket
leaking and was thinking about pulling the engine out and freshing it
up. I have found a 4bl intake from a FE casting number is C6AE-9425-G
I was wondering will it work, linkage mounting holes and etc.
it also has another tag on it 390 66 6 6B-357
If this intake was off a 390 what HP was it?
Thanks for all of your help on these old truck questions
has been fun taking this old truck out to some car shows and driving it
on the weekend for fun

352/390 Passenger Cars were available with either a 2V or 4V carb, but no FE truck has a 4V until 1974, and then only as an option for 390's.
The manifold you found is from a 1966 390 car (VIN engine code Z), will bolt onto your 352 engine since the intake manifold gasket is the same. Car parts catalog does not list the HP rating.

Intake Manifold Question ND ?
bertha66 thanks for the response on the information you had.
I see you built a 390GT for your ole truck?
Does it run on regular fuel or did you build it to run on premium
with a high compression ratio?
Stock build?
Thanks and let me know

It was built as a stock 390 GT engine that runs on premium fuel. The 67 Fairlane GT was a 325HP high compression engine.

You said the intake gasket was leaking but did not specify how it was leaking.
Does it have a vacuum leak causing a misfire?
Old FE's have the habit of leaking oil at the front or back of the intake to block mating surfaces either because the original cork gasket has broken down, or the engine has enough blow by from worn rings/cylinders and the gasket is being pushed out in the middle, causing it to pull away from the junction where the intake, block, and head meet up in a 3 way intersection. That gives the oil leak in the corners.
If it's just a bad gasket, the oil leak stops if you fit everything together correctly. If it's a blowby issue, your new gasket will start leaking oil again because the new gasket gets pushed out just like the old one from too much crankcase pressure. I've seen a band-aid fix to stop the gasket from blowing out, the short version is drilling small holes in the horizontal surface just big enough for coat hanger wire clipped off almost flush. the little barbs of wire barely poking up are enough to keep the cork part of the gasket where it's supposed to be.

Do it in stages like the intake system first then the exhaust with the headers. You will be able to see how your performance improvements are increasing as you progress.
Now with a 4 barrel and dual exhaust it will sound cool but you have to keep you foot out of it to get good mileage.
Good luck and have fun.....

I SOOO, agree with some of the guys here. Unless your going to open up the breathing capacity through the entire motor, don't waste your money. The valves and pistons will most likely not be able to handle the flow of a larger carb, no matter what you use as an exhaust system. And, for that size motor - being stock, your also wasting your $ on that large of exhaust pipe. Remember, exhaust gasses condensed greatly once it gets past the mufflers - thus requiring a smaller pipe.
