I am in the process of trying to change out my lifters on my 69 Javelin with a 290 engine, and I have removed all the bolts on the intake manifold but cannot get it to budge? I am to assume I do not need to remove the heads to remove the intake manifold? And on a separate question, I presently have a 2 barrel intake with a 4 barrel Edelbrock model 1460, and I am trying to find an intake that will accommodate the
4 barrel carb, does anyone know the model number of an intake manifold?

Correction on the carb number, it is a 1406, not 1460. Thanks.

First off, that cast iron intake is pretty heavy, at least 70 pounds or more depending on what else is bolted to it. The next thing is, if some used a ton of RTV the last time it was installed, it can be stuck pretty good. Of course this assumes you've removed all the fasteners that bolt the manifold to the heads, (Correction) six bolts on each side go into the heads. A good replacement four barrel intake for a 290 would be either the cast iron factory one available in 68 or 69 from the factory, sorry I don;t have a part number. Or, Edelbrock makes a performer intake that will bolt to that engine and do a great job for you. There are several other models available like R4B, Torker and RPM Airgap from Edelbrock and one other available from Holley IIRC. There are also tunnel rams and two four barrel intakes available too. Remember the 68/69 engines have rectangular exhaust port heads that changed to Dogleg exhaust port heads in 1070 and later, This means that the 70 and later intake manifolds will need the two center holes elongated to fit onto a 68 or 69 set of heads. Check the for sale section on this forum, or accumulate 30 or more posts on this forum and place an add in the wanted section. Ebay is another source as well as Craigslist.

It isn't at all uncommon for the intake to be stuck to the heads, some gentle use of a pry-bar in-between the block and the intake usually breaks things loose.
Edelbrock still makes an intake for 67-69 V8s, the Air-Gap #7530. Or you can keep a look out for older aftermarket or factory 67-69 4bbl intakes. I recommend against slotting holes from a later intake to fit 1969 heads. The later intakes are slightly wider by a tiny amount, but enough to cause a vacuum leak. It also isn't uncommon for the slotted holes to leak oil. Edited by akimmet - Jun/18/2018 at 10:04am |

...and there are _6_ bolts per side. Should be a significant gap at the front and rear with a thick rubber seal, so you can get a pry bar in that gap.

When I was a teen, doing my first intake maifold swap in the street,
there was two of us working together pulling intake bolts out. One of us left one in by accident and all the forearm strength in the world couldn't remove that chunk of cast iron. A friend came along and saw one bolt, covered in grease and oil, was still in. Intake came right off after that |

Two points.
As previously described, the dang thing weighs 70~lbs. 6 bolts per side, do count the holes. Even if liberally gooped up the manifold will fairly easily lift off. The valley pan gaskets do not stick that well. Not all of us can lift 70 lbs of stuck manifold at arms reach. I have many years of lifting weights at the Y and still find a challenge. If you are sure that all the bolts are out you can use a hoist or try prying under the front of the manifold. The seal is soft and a thin pry bar or a fat screwdriver will easily push through. Unless you are doing a restoration replace that old iron manifold with a good dual pane like a performer. The old intake makes a great mooring anchor for a small boat. |

A couple of years ago, I weighed a bare 1970 four barrel intake at 52 pounds.

I stand corrected.
The 290 intake should weigh about 50~ EGR manifolds are a tad over 70. I have two, a 304 2V and a 1975 401 4V Both are 70 give or take. Aluminum intakes vary a bit but I bet most at are under 15 lbs. |
