Heart riser question
Has anyone put a plate between the intake and exhaust manifold to keep from heating the intake gasses. Usually have better results with cooler intake gasses. I do understand the purpose of this heat riser. I am not worried about cold starts and such.
Since I have it all apart was thinking manufacturing a thin plate.. Just wondering what your thoughts were for blocking it off.
Thank you for your time.

Mr. SixPack
I totally understand. I have only built a couple of 6 's and mostly 8's. I too thought there should be no difference but was thinking someone here would have already been down this road. I am proceeding and will check it out.
I always look forward to your replies.

I haven't done it on a 6 cyl., but I did it on a 460 by using an intake manifold gasket for a propane engine. They have no passage for the heat riser. It seems like making a thin metal plate for the 6 cyl. would work. To me it's a good idea, especially in a hot climate.

Mr. Ozzie
I also was thinking of tin or something as it has to be real thin as not to offset the two manifolds. Looks like with a tin plate and a gasket on each side might be too thick and would cause miss alignment of the ports..
Am I overthinking the alignment issue????
How about filling up the intake side of the riser with the red fire caulk. would definitely stand up to the heat, Probably would not transfer as much heat, would not wrought and might be cooler.
Just thinking of different ways.

Where is the intake on a L6? It hangs off the side of the motor out in no where land with little heat around it.
I am running EFI exh. manifolds, they have no way to heat the intake manifold, but I use a hot water heater plate to heat the intake manifold.
Do I need it? Cant say but I did not want to take the chance of carb or intake icing, fuel falling out of the air and pooling on the intake manifold floor and making the motor run like crap.
I have run my truck during the winter here, it does get to freezing here, and it runs grate.
If I was going thru all that to block it I would also go with EFI exh. manifolds for better flowing, add the water heat plate but not run water thru it.
If you find you have issues when it gets cool then pipe water to it.

Where is the intake on a v8? ............ between 2 heaters called heads and the heat pump below it.

On the V8. the headers where most heat is produced is far away from the intake.
Yes the V8 intake is setting between 2 head heaters but cooled with circulating temp controlled fluid.
On the L6 the intake is actually next to and bolted TOO the header...... thus seems to me more heat on the intake....
Where is my thinking wrong.

Thank you Mr. F-250 Restorer.
Being new here, I did glance thru the engines when I was looking but missed the inline 6 300' s. My mistake.
Just went back and found it.
Now how do I request the moderators to move this thread.
Thank you again
Alex

Heart riser question from another forum
Guys,
If you have any input concerning blocking off the heat riser on the 300 please continue reading.
I posted this question on the 73--79 forum.
Being new here I did glance thru the engines performance and missed the 300 or would have posted here first.
Finally F-250 Restorer brought it to my attention "you should post this on the Inline 6 Forum" I thank him for the redirection.
I do not know how to get the moderators to move it here so I am still looking for answers. This group should have the answer.
If you have time please go to the 73-79 F-100 or larger forum to read the question and responses I believe it is on page 3 now..
Thank you, Alex

Hi Old Guy F-250
Only the moderator of that forum can move it here. Maybe shoot him a message?
Otherwise, suggest copying and pasting it here and just start a new thread.
Lastly, you can also paste the link here to that thread, so people here can see it and jump on over and help.
Thanks!
