"Kubes;" Why such a big difference in gap for 85HP v8, as opposed to a 100HP v8?? Regards, Steve Lee

As far as I knew, there was no difference. It's .025", period. Where did you read the 100HP plugs were gapped wider than the 85HP plugs? Mike "Kube" Kubarth

"Kubes," In my "1949-50-51 Ford Passenger car Shop Manual," page 216: it says the plugs are to be gapped at 0.o29-0.o32. , so I gap them at 0.031. That's the 100 H.P. V8, and having no spec for the 85H.P. V8 I figured they would be gapped the same as the 100 H.P. V8.P.S.: Regarding my '40 with the plugs gapped at 0.031-; It starts instantaniously, on a 6 volt battery, and revs like the roar of a lion! I can feel the power in the accelerator pedal when I rev it, it's so smooth!! Where did you get the plug gap info on a '40 V8?

Any Ford book dated near 1940 as well as a Motors manual dated 1941. Mike "Kube" Kubarth

"Kubes"'That's kind of odd- your sources and the Ford manual I mentioned are in dispute?? I don't mean to argue with you personally,- "But it leaves a question in my mind as to what book 0r who to believe?? When I was 20 I rebuilt my 1950 v8, under the over site of the ownerof a local auto parts store, in the back of the store. He had a 1937 with a V8, that was all hopped up, and he raced it on an oval blacktop track; (Wall stadium in New Jersey). He, and a service manager,Rick Ricardo at Downs Ford, (The local Ford new car dealer) Told me the plug gap on my 1950 Ford car, was 0.029- 0.032, and the points were set at 0.016, and to time it to the dot on the lower pully when it is aligned to the pointer on the front of the motor. (That's 2 degrees advanced) I did just they all of these years on 1949,50, 51 Ford v8 cars, and the all started easily and ran well. MOTORS AUTO REPAIR says up to and including 1942 plug gap for V8 is 0.025,and after that it is 0.030. Why did they do a smaller plug gap on the V8's early on? What was the advantage? A little bit hotter spark?? , or what. Educate me if yo know. Regards, Steve Lee

I don't see a big difference here .025 to 0.30 for my 1934 Ford 85 HP cars. If it's a fresh engine, I like .025, for the high mileage ones .030. Both work just fine. 1934 Ford's since 1972

"KUBES," I don't have any books that old; except for a Motor's Auto Repair Manual that has 1935-1949 in it, that I had forgotten to look for; and it shows V8 spark plug gap from 1935 through 1942 is .025; thereafter it's .030 I don't refer to those manuals very often, and all of this made me look to see if I had a book that old,THANKS TO YOU!!
