Re: [Amc-list] intake question

["Armand Eshleman" <aje1@xxxxxxxxxxxxxxx>]

I agree with Matt about the exhaust crossover not changing the outcome on
anything but the cold engine drive-ability. Either this engine has thin
cylinder walls, poor coolant circulation (pump screwed up, head gaskets or
intake to cooling passages in head messed up), a bad  thermostat or
radiator, or like Smokey says poor tuning.

Have any of you guys ever heard of Hylomar? It's a sealing product made by
Rolls Royce and initially used for aircraft engines. It is not oil soluble.
We used it for sealing up the transaxle cases in the Formula Ford race cars.
I don't remember using it on the intake manifold, but then again there's no
coolant in a four cylinder intake manifold. Anyway it stays very pliable and
it makes it easy to disassemble things, unlike silicones, which take a
prybar to get the things apart. but I do remember using red colored silicone
around the water pump. Sheesh it's been a long time since I have done any
engine work. Gotta get going on that 360 or a 401 for the Javelin.

decided that this is the best course of action and have considered other
courses of action) I want to R and R the original intake manifold off of a
'68 390 AMX, block off the exhaust crossover passages, and install an
electric choke on the original Carter AFB.  Any suggestions on the "R and R
and block off" parts of the procedure?  I've used a Permatex product to seal
off the thermostat housing (with gasket, of course) and was wondering if I
ought to use a similar product for the intake gasket.
