oh snap, thanks for the info/pic! so I should be good with my stock single groove? I'm on the hunt because of what the vintage Air rep told me on the phone, but based on your setup he's wrong... I don't doubt you at all, the conflict is just a bit confusing. I'm immediately pretty disappointed...

correct, I called vintage Air and they said I need to switch to the 2 groove.

fixin to add vintage Air to my 440 big block (1969 engine in a 1970 challenger). I need to swap my water pump pulley to a 2 groove AC friendly one. new ones run $112+ dollars. frankly, I don't need a new one. it's not a show ride so I'm not looking for anything fancy, performant, special, or...

to respond to this original question, you can tell the difference for the newer version of Green bearings (MO400) from the old ones (RP.. something) because they're much beefier/heavier and the plate part that bolts on (circle with 5 bolt holes and the the straight edge) is separate from the...

I always run 93 octane (it's the highest available locally and conveniently) with the minimal ethanol possible (which is usually 5 or 10%). I'll give some octane booster a try

440-6 bored .30 over, compression is over 10:1, maybe 10.25:1. Lunati Voodoo cam 10230702 but mainly stock beyond that. car was running hot at idle so i checked the initial timing and it read only 3 degrees BTDC! definitely doesn't help the temperature. Vacuum advance disconnected. i wanted to...

good to know, thanks!

yeah, I forgot to mention that I replaced the fan clutch with a new one. even tried a larger plastic one for a bit but switched back to the factory one (still using the new clutch fan) after it proved no change. radiator is 26". pulled it out and had it tested about 3 years ago, they said it...

I'm less concerned about boiling explicitly and more concerned about damaging various engine parts. isn't that still likely? I can't imagine factory recommendation would say that high a temp is safe, right?

I have this same problem 440 bored .30 over. freshly rebuilt in 2015, I'm not sure which head gaskets are on it. clutch mechanical fan with a shroud. I've been through a variety of thermostats. despite the thermostat, she always runs well while moving (temp decreased) but when stuck at red...

I found a solution to this problem so I'm posting for documentation in case anyone has a similar question. I called Holley directly and they really had nothing to offer. I described the situation in detail and the service guy had no leads for products from Holley themselves; he did explicitly...

i guess i forgot to mention that the base on the backside was the 12R-4254B stamp, assumed it was the model. the top is stamped D-1565 and 6R 3406B. i guess i'll go look up this one also...

thanks for the info friend! the inside of my original bowl looks like it's stamped: 34R4 649 B i'll call holley and try to confirm also. give them my model number and cross ref. good idea! are those pics of your replacement? looks like the left/driver's side plug is external. my plugs are up...

i was told it was 69.5 & vacuum secondaries which is why i've always believed it! never thought to question it. i guess it could be 70 also then? i can take more detailed pictures (see above post of pics) if it helps determine it.

thanks a lot! aside from fitting correctly, getting the one with the plug on the left/driver side (so that the fuel line can do on the right/passenger side) was a big concern for me because it doesn't seem blatantly obvious in the product description. i do believe they are vacuum controlled...
