Re: Ram Horn Manifolds
So are these the 'sloped back' ram horns?...and by the sounds of it with respect to the pipe threads you an emissions A.I.R. system you are trying to connect into them and that is what cracked?

Re: Ram Horn Manifolds
I bought some online....had them ceramic coated....watch the flange where the dounut goes.On mine the flange contacted the block before the manifold flattens to the head....had to grind it down some

Re: Ram Horn Manifolds
there is a heat riser you have to put in on the driver side.The manifold dose not have that round grove in the driver side only a flat exhaust triangle gasket goes then then the heat riser then the donut Most guys forget about the heat riser.They make them with or with out the flap.You have to use long studs.For this one.Plus i take3 them to a engine shop and have there planed No need for gaskets ever.You will love your self later.
One last thing 1973 or 1974 Corvette was the first year they used HEI So when you buy plug wires buy them for that there long enough for 1-3 2-4 plug wires to go throw the motor mount's to keep your engine from looking all cluttered up.You might have to put something that hangs from your oil pan bolts to keep your wires away from your exhaust. One more thing running the plug shields help from cooking your wires plus there printable or Keep them silver but they like to rust Last edited by stsalvage; 04-16-2018 at 01:53 AM. |

Re: Ram Horn Manifolds
Everybody seems to put pipe plugs in those AIR injection holes which is incorrect, they sort of fit but the proper plug is a tube plug, the threads in the manifold are straight and not tapered as the hole was designed to seal the air injection tube, the hole is tapered at the bottom too for the tube....the proper tube plug will have the taper to seal at the bottom of the hole.
Cranking a pipe plug in that hole is the same as cranking a large threaded bolt in a pipe fitting, its just wrong. |
