Last I talked to him Dave had SS plates available - he had also said he was planning on some mild steel plates (for substantially less, I believe about $65 shipped or $60 out the door) and I am waiting for them to be done. I am in no rush so I have not pushed him.


my impression is that Offy made the bolt pattern in their manifold to match the Ford manifold so the same heater plate would work on either - can someone verify that?

 

Offenhauser designed the bolt pattern to match up to the top of the stock exhaust manifold (which is where heat was originally sourced from). So yes, the heat plate will bolt to the bottom of the Offenhauser.

 

I just received the SS version. Paid $118 and may not even use it here in Texas. I did use it as a pattern to create a cover out of sheetmetal that I will use initially.
Still not sure how well the top side bolts (they go all the way through) will seal up if I decide to use the heating plate.

 

Just run a bead of RTV around the mounting base on the intake and it will seal fine.

 

I have no idea if anyone is still looking for heat plate for Offenhauser intake for 300 i6. I am located in PA and I am working on my engine right now. I could not find anyone who makes them except Raso Enterprises. They are located in Canada and I had a pleasure to talk to Frank from Raso. He is really responsive through email. Their website says right now that you can pre-order them, however I talked to Frank this morning and he have 5 of them in stock it just takes a while to update the web.
Once again the company web: Raso Enterprises Store and in the search box just type KIT0008.
I am not related to this company and I am not making any money of of this write up.
I am just really excited to find this part. I will able to make a heat plate myself but it will cost me probably a little more because basic Raso kit cost 64$.
Oh and another thing shipping cost me only 8 bucks because Frank said he can ship it from upstate NY.

 

Thanks for the info ZEE! I'm doing my build right now and thanks to this thread and some others I learned about the importance of this heater plate on the Offy C. Was very happy to hear someone is still making these as I don't have welding equipment to build one myself.

 

Seriously think about a Volley 4bbl Economaster 450cfm spreadbore mech secondary. As another carb choice for your combo: kits still available, economical carbs with a rorty performance feel with the secondaries open on a big L6, especially with dual port offy manifold, I think with a good carb you'd be very happy with this model choice & potential to get some great cruise mpg's too. Don't forget to recurve/quicken the distributors advance curve..especially just off idle to about 2,500rpm to match the cam.
Cheers APH.

 

I bought mine from this guy:

Housing Suppliers
Got it in 2015 , don't know if he is still doing them. To be honest, have yet to hook it up (though it is installed) - today is the coolest it has been. Barely below 50. Up to now it has run great without it. Guess I also need to think about doing anti-freeze in the next few weeks too!

 

Can you email me please? I would like to buy a heating plate

um this thread is years old dude. They're not selling them anymore just build your own. I built mine in like an hour

 

Admin,

This guy is as helpful as **** on a hog. He first stated that he could make the plate in half an hour.... now he says an hour. Boot him.

 

are you being ironic right now? because that is... im not sure i have words

 

Yeah, I'm not sure what his deal was. Quite the tantrum for their very first post on here, and over something completely insignificant.

 

 

Heya Kevin!
That's an interesting idea, I've never seen that before.
My only thought on it is it's a one way, so you wouldn't get flow. However, maybe that gives it a more manageable heat level? Like 350° when it leaves the manifold, but at the end of the pipe, it's a more tolerable 200?
