shorty spark plugs

My buddy is running some Accel shorty plugs and they foul pretty easy. Is there something better he can use? Must be the same length as the Accel shorty plugs.

Re: shorty spark plugs

I find that my NGK's burn really well, and they are almost as short as an Accel shorty plug , plus alot cheaper.

Re: shorty spark plugs

the problem is prob the tune, not the plugs unless the plugs are way to cold of a heat range

when your credit cards are maxed, have the limits raised

Re: shorty spark plugs

I know Delco has a shorty version of the R43T for you #4,6,3 small block guys.

Couple of junkers and a few clunkers.

Re: shorty spark plugs

Anyone got part numbers? I know alot of people have problems with the accells fouling. It might be the tune, it is a fresh engine. I think its set up fairly well but not sure of the carb settings.

Re: shorty spark plugs

Champion uses numbers like CJ6, CJ7, CJ8 and DJ6, DJ7, DJ8 for shorty plugs for lawnmowers. The C plugs have gasket seats, the D plugs are for tapered seats.

The shorty plug isn't that much shorter than a standard plug.


If it's just a access problem I made one of these.

=========================

Oil or fuel fouled?

Assuming fuel fouled are the plugs too cold of a heat range as that can cause them to foul easy & in that case try hotter heat range plugs if your 100% sure timing & carb tuning is where it belongs.

Esp base timing when running non GM aftermarket cam that generally requires 2x-3x more base timing then stock gm cam does & when base timing is retartded it upsets the vacuum signal/low vacuum to carb causing running rich issues.

But if plug heat range is correct for application & plugs foule fairly quick then you likely have timing/carb tuning issues that need to be addressed that are causing plugs of proper heat range to foul.

I am also assuming plug wires,coil,cap & rotor,air filter (not clogged/dirty causing rich mixture) are all in good cond here too and if they are not in good cond they can be part of issues causing plug fouling too.

Might be a little of both. Its fresh but burning more oil than I would be comfortable with but also feels like something is beng held back when he opens it up. All the parts are in good condition or new. Base timing is 16-17 degrees initial with 37 total.

The problem is the heads are angle plug and the headers are not ment for angle plugs. He dimpled tubes and re positions one of them to clear. They CAN NOT be any longer than the Accell shorty plugs.

His shorty plugs are a different part number than your showing and they are quite a bit shorter than a regular plug. There is no room for any longer plugs. They will hit the header tubes.

Re: shorty spark plugs

Accel also makes silver tip plugs that can be had in the shorty version. Just add another "S" to the part#....for instance, the 416S plug would be 416SS for the shorty silver tip. I don't know if the silver tipped ones would actually be less prone to fouling or not though.
