Would appreciate advice as to the correct spark plug gap when using Joe Hunt Mag Look Distributor in 49-53 8BA Ford with Autolite 216 plugs - Engine has Offy heads, 2 Strombergs on Offy intake, Isky 400Jr. cam, and headers - Thanks in advance for your varying answers Dave W
Found this....Spark Plug Gap- For street applications, use your engine manufacturer’s specification. https://www.taylorvertex.com/catalog/pdfs/Electronic_Distributor_Installation.pdf
I remember the day's of indexing the plugs so that the gap faced in between the two values. I still have all of the index washers I used to use when we were racing. Jimbo
J2X - Have you...say...called or e-mailed Joe Hunt..? Seems to me that that would be the most appropriate location for the best (I hate that word) answer..! Mike
If you call 'Joe Hunt'...ask for Roger Gleason, as Joe's been deceased these 15 years... but with that distributor, its common application would be preferable. The distributor doesn't know what engine lies below, and the HEI design was of GM origin... Good question, actually.
Yes and no... the compression matters. More compression requires tighter gap. Sent from my SM-G965U using The H.A.M.B. mobile app
There are pros and cons about those magneto look-a-like units. I'd always have my previous unit along with me on a trip including the correct tools and a timing light.
Odd... I learned how to gap plugs from the msd instructions that came with my distributor... low compression motors they spec'd up to .050+ gap Sent from my SM-G965U using The H.A.M.B. mobile app
I agree, though wide spark plug gaps puts the stock points style rotor and cap under a lot of strain though, they have closer spacing of terminals and misfire or arcing can result.
electronic distributers commonly gap between .040 and .044. Joe Hunt should have info on what the recommended gap is for that particular distributer. Tyr google; google is your friend.
