  1. Happy holidays to all: I am putting a 64 aluminum 4bbl manifold on my 65 300 replacing the 2 bbl. I just got the gasket set and the gasket has the holes at the rear of it for the two water passages closest to the firewall. Yet the aluminum intake has those two holes blocked off unoike the cast iron piece. Has anyone tried grinding open those two rear holes to allow the water to flow through there? The casting does have the holes but they were blocked during casting. I am wondering if I open those hoes up if the original flow will exist as it did in the cast iron manifold.
  2. Hi: Again I stand corrected. There are four water passages and four exhaust passages where as the 4bbl has two water passages and no exhaust passages.
  3. So I removed the old 65 300 2bbl and manifold. In comparing it to the 64 4 bbl manifold I see two distinct differences. One is that there are six water passages between the heads and manifold on the 2 BBL but the 4BBL manifold has just two that do happen to line up with two of those on the heads. So if I put the 64 4bbl gasket on it will block four of the water passages. Do you think this would limit the water flow into the heads enough to be an issue and would the gasket sufficiently block the four unused passages? Next I found that the ports out of the 4 bbl manifold are smaller than those in the 2 BBL and thus in the heads. So with the 4 BBL gasket in place it will actually block part of the port into the head. Do you think that would be an issue?
  4. Hi Guys: Thanks for the advice. I have looked extensively at the monifold and there are NO water passages into it from the block side. The choke does look differnet than the two barrell choke which is feed hot air throuh a small pipe from the exhaust manifold. The 4 BBL has a threaded fitting feeding the choke. I wonder where the source for that was. So the only way there could be water flowing into the manifold is if it came via a pipe/hose into one of the openings in the top of the manifold. I am hearing alot of different suggestions and am wondering now if perhaps there were more than one aluminum intake manifold used in 64...not an uncommon practise at the General.
  5. Hi John: Thanks for the information. If I hear you correctly then I should be able to add a manual choke and it should work just fine. The only other issue would be that the hot water will not flow to the base of the carburator and given that I do not drive this car in winter then perhaps that is not an issue. Your opinion on these two issues would be appreciated. I would get aluminum heads but I have heard stories that it is hard to find ones that are not warped. I found the torque settings to be 25-30. take care, Walter Gerrard
  6. Hi: I have received mixed messages as to whether a 64 300 aluminum intake and 4 bbl carburator will go onto a 65 300 engine. Even though the heads are different I was told that the aluminum intake would fit just fine on the 65 300 with it's cast iron heads...(as oppossed to the 64 which had aluminum heads) Who know for sure????
  7. Hi All; I am installing a aluminum intake maifold and it's original Carter AFB 4 bbl carburator on my 65 Skylark 300 engine. This manifold and carb are actually from a 64 300 but they appear to fit just fine. Does anyone know the torque settings for the manifold and carb bolts? Anybody ever do this before and have any gotchas for me? Anybody know who stocks the bolts for these puppies?
