Rear water crossover on my intake?

Phantom5oh · 01-03-2002, 12:16 AM

I am thinking about getting a new intake for my carbed Stang this winter. The one I am considering doesn't have a rear water crossover. Will this be a problem? Is it going to make my car overheat? The Victor series intakes don't have rear water crossovers do they? The local Machine Shop said that I will be ok because "the rear crossover doesn't do much for cooling." I don't know if I belive this can anyone give me any insight? My mods are in the link in my siganture.

You will be perfectly fine. The only practical purpose that water passage has is allowing access to the engine coolant for temp sensors and thermal vacuum switches.

Take care,

Thanks Chris, I wasn't too sure if the Machine shop was giving me a straight answere, because he wouldn't tell me what the purpose of the crossover was. He just said you don't need it, it doesn't do much for cooling. I figured there needed to be a reason it was used on most intakes. Seeing as I don't run any vacuum switches and the temp sensor is up front I am golden.

I have an intake without the rear crossover passage. I have a question about gaskets. Are there special gaskets for these manifolds which do not have the cutout where the passage would be. Would a regular gasket work just as well.

I have never seen one. They wouldn't be cost effective to make. The only way it could leak is if either surface was warped, in which case it would leak anyway!

Take care,

I HAVE seen the gaskets that don't have cut outs for the rear water crossover. I have even seen them used on cars WITH the crossover. They are more expensive though. Chris is right, don't bother with them.

I only began to work on cars about a year ago. So I don't know these things. I have another question. I stumbled across a site today about spark plugs. It seems to me that the spark is one of the key parts of the cumbustion process. Yet I don't know how to pick the right set of plugs.

I tried to figure this one out on my own but I just got more confused. I understand how to properly set the gap. but what heat range or shape or type.

Sorry, I didn't mean to sound like a jerk. Ok your right about the plugs being important. I would say that stock heat range plugs would be good for most near stock or mildly modified Stangs. You would probably be happy with an Autolite #26 plug, or equiv. If I'm not mistaken that is the right heat range and shape for a 302.
