Understanding gap requires examining multiple perspectives and considerations. AC Delco R45TS gap out of the box - Team Chevelle. It's SOP to inspect & gap new spark plugs to your desired gap before installing them. They could have been dropped, thereby changing the gap, etc. In this context, nEVER assume they are gapped correctly out of the box. How does the manufacturer know what YOU are going to gap them at? Stihl Ignition Module Air Gap...
- Arborist, Chainsaw & Tree Work Forum. Here's the problem, the stihl setting gage seems to set the air gap too tight, like 0.004" measured between the ignition module arms and the flywheel magnets using a feeler gage set. It seems as though the center coil pick up on the ignition module has a wider air gap. Equally important, now my question, what is the proper way to measure an ignition module air gap?
Real world HEI spark plug gaps - Team Chevelle. This took creating "drivrs" in the HEI module to increase dwell charge time to the coil, store more energy, to make the larger gap function correctly over a point system. Furthermore, along the development of the HEI, some engineers decided that to fire off ever more leaner fuel molecules, the HEI needed increased spark plug gaps. Spark Plug gap on a 454 with Edelbrock 35830 EFI, 1971.... Hello All, Just looking to see what I should gap spark plugs to with a 454 using an Edelbrock 35830 EFI kit?
In this context, i read 0.32-0.45, I'm leaning towards the high side. Building a 454 030 overbore and pre gapped rings are 25/26 thou gap. That is a bit more than I would like. It's important to note that, ok, or do I have to buy file fit that cost a fortune?
Will this gap give too much blow-by? Another key aspect involves, spark Plug Gap - BBC - Team Camaro Tech. Things that determine resistance is the plug wire conductor (metal conducts better than carbon impregnated fiberglass strands), the spark gap, and the resistance in the plug (the R in the designation of an AC-delco plug denotes an internal air gap to prevent power from bleeding off too soon).
Brodix Dual Plane Intake BBC - Team Chevelle. The Air Gap has bolt holes between the intake ports. My cylinder heads don't have those. Equally important, i'd probably have to weld those shut.
Port matching might be an issue. Furthermore, i did notice that Air Flow Research has introduced a new dual plane Magnum intake for rec port BBC. It's 1/4 inch taller however. Not sure of the availability.
