I've searched all over the FTE forums and on other forums as well, but I can't find the size of the bolts for the heat plate that bolts to the bottom of the Offenhauser DP intake.

The two that go all the way through aren't an issue, but I really need to find out what size bolt I need for the one that screws into the intake. I'm having a plate made and would like to install it this weekend.

I've seen other posters request this information, so if anyone has it, it would be very helpful to make it a sticky.

 

"Size of the bolts ..."

There is only one bolt that is not all the way through. An easy remedy would be to buy three--5,6, bolts of various diameters and threads so you are ready, then return the unused one for your $ back.

Also, if you are having a plate made, then you have the manifold? The threads are in the manifold, so you should be able to check? Possible?

Good luck. Call Offenhauser as a last resort, or Summit Racing who sells them.

 

Ok, for future reference, here are the bolt sizes for the Offenhauser 6019 DP intake for the Ford Inline 6(300/4.9):

Straight through holes are drilled for 7/16

The threaded hole is threaded for a 3/8 standard bolt.

I called Summit who gave me the number for Offenhauser. I couldn't find a website for Offenhauser, or a number. They don't seem to be on the web.

Offenhauser's customer support number is: 323.225.1307. They are on California time.

 

Phethean Racing Products - Offenhauser

That is the only actual "Offy" site that i know of.

 

Offenhauser doesn't make it easy to view and compare their products and to verify proper application. A factory web site with large pictures (with zoom), multiple views, measurements, suggested list prices, and a comprehensive description and application of each product would make it easier to buy their products. How about a list of distributors? An easy way to get answers to questions would be nice, too. All on one web site. Maybe such a site exists, i just haven't found it. I go away now...jack


Same for Trans-Dapt

 

The short bolt you need is a 3/8 - 16. you should be able to find one at the local hardware store no problem. Just remember you need to it be short, that threaded hole is pretty shallow.

To be honest I just walked into the ACE hardware with my intake in hand and tried bolts until one worked. They'll give you a couple weird looks but once you tell them why you're dragging around an intake everyone is plenty willing to help.

Edit: Guess I should have read all the posts, look like you found what you needed. Good luck.

 

LOL, glad I'm not the only one who's walked through a hardware store with a manifold in hand.

 

I wouldn't mind walking through the HW store with the intake, which I should have done before mounting it, but I surely didn't want to take it off to figure out what the bolts were!

All's well though, I have the heat plate mounted along with a heater core bypass. I should be in good shape now for the winter.

Heh, no, that's asking a lot to have you take the whole thing apart to go match a bolt.

Glad you got it all set up and ready to go! I know I'm curious what'll be in store for me this winter on the same regards. I've never been able to put a heat plate on mine until I came up with a unique solution this summer (the previous owner of my intake messed up the bottom), so it'll be interesting to see the differences with warmth now.

 

I agree! It's 2013...way past time to have a great website. Offenhauser has a great name, but they seem to be stuck in the past as it relates to making it easy for customers (and potential customers) to get information. Holley, Edelbrock and others all have that type of information readily available on the web.

 

Thanks, TB. I was wondering if i was the only one wanting to buy stuff - only to find a lack of info to make a wise purchase. ...jack
