Randal do you have room to make a heat break in it of some sort?2007 SBN/A Drag Week Winner & First only SBN/A Car in the 9's Till 2012

I geuss that looks like cast iron to me, and you have added a heat sink that's going to draw all the heat it can. I am thinking of a hard wood or multi gasket heat break to not let the heat get to the manifold as much between the manifold and the head2007 SBN/A Drag Week Winner & First only SBN/A Car in the 9's Till 2012

It'll have a lot of heat flow through it, but it shouldn't be any hotter than the cast iron itself. The only temperature benefit of an aluminum intake is all the aluminum can cast off heat, and cool down quicker, but it'll also wick the heat from the head quicker. That being said for my good turbo engine I do have a composite intake/exhaust gasket, but I'll use a standard gasket unless I'm melting O-rings I'm not going to be too concerned about it.
The straight six poses the issue of the exhaust in more contact with the intake, but my old Jeep's cast iron intake didn't seem to have any issues.Escaped on a technicality.

I'm still learning the basic of efi. so if this is stupid I'm sorry.
I've read this thread and I like the threaded bung idea, guess that be to easy..
BUT why couldn't you drill and hone the intake hole a little undersized, then heat one(intake in oven), freeze the other( bungs)
and then press them in with a press or light taps with a plastic hammer..maybe with a little red lock tight for insurance.
I'd think this would work, and not cause any vacuum leaks.
What says you??

I think Green locktite is designed for locking in bearing races and would work well for what you're saying NewEngland, a press fit would be good but is tough to get right at home with out specific machining tools. I think the NPT idea is brilliant if someone can get bungs with thick enough walls to fit into a standard NPT size.
How much did the weld shop charge to weld in the bungs?There's always something new to learn.

The weld shop charged me $100.
I would change the method that I did on mine. I would weld the bugs in then thow intake back on the mill and drill the holes and then hone to the finish I like.
It was a pain in the a$$ keeping every thing straight.Last edited by 79camaro; June 24, 2013, 11:01 AM.Drag Week 2006 11.00 index DNF
