spark plugs

Recently finished rebuilding my 225 oddfire. what spark plugs is everybody running? I know I may have to adjust heat range a little after a few hundred miles. here is what it looks like now. thanks in advance

Here's where I am now.

 

Autolite 85's

 

That is a beautiful set-up. It deserves an HEI distributor though.

 

What is that dipstick from??? Maybe I have the wrong one, but it doesn't look like yours???

 

thanks a bunch. i'll try the 85's. thanks Walt, and your probably right about the HEI. maybe later when I get it running. the dipstick is the same one that was in it when I bought the motor, correct one, don't know. I painted it red just because I had red paint handy, I guess.

 

I am using the factory recommended heat range, but I am very specific about my brand.. I use Bosch supers.. They are not expensive as compared to the exotic platinum multi electrode split tip unobtaniums.. I like the copper cores of the supers..

 

I have Champion UJ-12Y (same as earlier J-12Y)
Or try the hard to find Prestolite 1442

 

Beautiful work. Congrats.

 

I always run AC Delco Platinum plugs in everything I own. They run about $5.00 per plug but I've never had any issues running them.

On a side note, does anyone else have trouble screwing in their plugs into the Dauntless? Every Craftsman 13/16 deep socket I have is too thick and won't fit inside the outer diameter of the block. Its the stupidest thing I've ever seen.

 

yeah, I had that issue too. i happen to have a real spark plug socket that is real thin for it. Says on it to not use it for anything else.

 

I have spark plug socket as well, and it was too wide as well. Never seen anything like it.

 

AC Delco Rapidfire #7 here...

 

Every Bosch plug I've run in any vehicle has caused issues at some point as have Champions except their race quality plugs. The consumer plugs stink. When the Jeep still had the F head put in Champions from a local store and it wouldn't start. Put in the worn out junk plugs and fired right up.
Autolite in the 231 but have to change them regular as they wear out pretty quick. Otherwise typically NGK's work well. There are others that are ok as well.

 

delco plugs.champions are for lawn mowers,foreign cars use foreign plugs.

 

I am running AC Delco R43s plugs right now, but I also have HEI. I just looked up plugs for a 1976 and 1975 with a 231. This engine has the HEI distributor that I put in my 225 and it specs AC Delco R46SZ. The AC Delco brand was just to compare apples to apples. I guess I will be getting new plugs today.

 

I just swapped mine over. runs the same so far. .060 gap is the spec.

edit. runs better with smoother power at low rpms.

 

which E3 are you running? I looked before but didn't see a match.

 

Chuck, what improvements have you seen with the E3's? Which ones are you running? What with all the hype on them I've seen, I thought I would try a set of E3.52's to replace my RJ12YC's.
