tim boyd Posted July 3, 2014 Share Posted July 3, 2014 (edited) Anyone have a picture of the Chevy Fisher I6 cylinder head (as included in the AMT '51 Chevy Bel Air) that would show the location of dual spark plugs per cylinder???? I can find plenty of pictures of the cylinder head/spark plug locations for Fisher heads with single spark plugs per cylinder, but the AMT kit includes a distributor cap with 12 (not six) spark plug wire terminals, leading me to believe that there must be or have been a Fisher dual plug cylinder head out there somewhere! And if so, I need to see a picture of it so I route my spark plug wiring properly. Thanks in advance if anyone can help....TIM Edited July 3, 2014 by tim boyd Quote Link to comment Share on other sites More sharing options...
1930fordpickup Posted July 3, 2014 Share Posted July 3, 2014 http://www.hotsixes.com/chevy-inline-6/ I found this site but I did not see anything about a dual plug head here. Not that it is the bible on sixes but does have a bit of info. Quote Link to comment Share on other sites More sharing options...
Brett Barrow Posted July 3, 2014 Share Posted July 3, 2014 I'd try Inliners.org http://www.inliners.org/ or the HAMB http://www.jalopyjournal.com/forum/ somebody on one of those is bound to know. Quote Link to comment Share on other sites More sharing options...

Ulf Posted March 19, 2023 Share Posted March 19, 2023 Hi Tim Did you find a picture? Now it's my turn to pull what little hair I have left, I really want an injection engine in my TROG project. //Ulf Quote Link to comment Share on other sites More sharing options...

Now it's my turn to pull what little hair I have left, I really want an injection engine in my TROG project. You did notice, I suppose, this thread is eight years old? Anyway, the Fisher heads were developed from the Wayne and Horning heads produced by Wayne Horning. Fisher bought Horning's tooling and produced heads for about 4 years, with only relatively minor modifications IIRC. The hot setup had 12 ports, and a cross-flow configuration. Here's some dope on 12-port heads. https://www.inliners.org/12_Port_Story/main1.html I believe the twin-plug head was built by Kay Sissel, but have nothing to confirm that as yet. EDIT: Here are a pair of Hilborn-injected non-crossflow GM inline sixes Edited March 19, 2023 by Ace-Garageguy 1 Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted March 19, 2023 Share Posted March 19, 2023 (edited) Here's 68 pages of six-cylinder drag cars, many old, in-period. Happy hunting. https://www.jalopyjournal.com/forum/threads/six-cylinder-drag-cars-photos.532331/ And unfortunately, it looks like the links to Sissel Automotive and the history of Kay Sissel are dead. http://sissellautomotive.com/cgi-sys/suspendedpage.cgi EDIT: This appears to be a 12-plug, cross-flow head, running a custom front-cover distributor drive, made by Horning in 1951. Note the Hilborn injection. Edited March 19, 2023 by Ace-Garageguy Quote Link to comment Share on other sites More sharing options...
Ulf Posted March 19, 2023 Share Posted March 19, 2023 Many thanks I will come back with some pictures during the week and some questions. I think the AMT valve cover looks strange. //Ulf 1 Quote Link to comment Share on other sites More sharing options...
Tabbysdaddy Posted March 21, 2023 Share Posted March 21, 2023 Eight years old and still useful. I guess I'm six times more useful. Quote Link to comment Share on other sites More sharing options...
Ulf Posted April 2, 2023 Share Posted April 2, 2023 So, now I have tried to get the plastic pieces together... The in line six in the AMT 51 Chevy was a bit crooked so instead of working on it I made my own engine block which at least is perpendicular, "the clutch" is an old Monogram rim and a part from the 51 air cleaner. The ribs on the liftgate are a pair of valve covers from an AMT Corvette. What do you say, can this pass as an in line 6 with Fisher Cross flow head ?

Ace-Garageguy Posted April 2, 2023 Share Posted April 2, 2023 (edited) You're in the ballpark. I haven't really been looking, but I came up with another image (see link below for more). EDIT: The source calls this a "Wayne F Horning 12 Port Head"... and as Mr. Fisher subsequently bought the tooling from Mr. Horning, it stands to reason that this is also what may incorrectly be referred to as a "Fisher" crossflow head.

Ace-Garageguy Posted April 2, 2023 Share Posted April 2, 2023 (edited) Here's a bunch more... https://www.jalopyjournal.com/forum/threads/the-scrambler-1960-gmc-302-12-port-nitro-fed.737695/ EDIT: It looks to me as though your intake and exhaust ports should come out of the black part of the engine you've built, and perhaps you might fiddle with the proportions some. Right now, your exhaust pipes are coming out of what should actually be the top of the block. Edited April 2, 2023 by Ace-Garageguy Quote Link to comment Share on other sites More sharing options...
