Hey Don, i have the gauge connected and I'm seeing Hey Don, Got the auto meter wide band installed. I need to have a co pilot record exact numbers but here's what I'm seeing at a glance: Idle 12.5-13.2 Cruise: 12 something to 13.8 WOT 12 something and just a tiny ping for a split second when...

Thanks CuriousYellow71. NGK XR5 plugs. I'm going to see about the AF mixture and go from there. Thanks for the tip on the Dike product. It's just tiny leak and we will be pulling the heads next months so I'm probably good.

Outsider: THANKS A MILLION for the offer!!! I'm ordering the AF meter and jet kit so if that doesn't fix it I'd Love to run down to hang out and compare our setups. Happy to do it anyway as it's always awesome to see what little things can be different between similar setups. I'll check back in...

Outsider, THANK YOU so much for the kind offer. I've ordered the AF meter and Jet kit and Autometer and a jet kit it is. I figure I can wait on a FI upgrade for a while so this is worth the investment for now. I'll report the results!!

Thanks Mike, that's an excellent point. There are two ports on the combination valve to go to the front, one to the back. Somewhere i read that the combination valve can either feed both sides or you can plug one of the holes and do a Tee to run to either side. Sounds like I could solve this buy...

Hey Don, Can you recommend an AFR Meter? I didn't realize how spendy they were and I don't want to get the cheapest one if that's not going to be accurate. THX!!

Thanks 66Satellite47. Would you rebuild rather than just get another re-built one from the parts store? I assume so since you'd KNOW that it was good inside, but I just wanted to confirm. I did just replace from the parts store and it behaved EXACTLY the same way, so between that, and my...

Hey Just to update this, The bar never came. it was Back-ordered, and so I just have the LCA's with no sway bar. 1.03 PST springs, handles GREAT. Looking forward to see how much better when I figure out a sway bar solution!

Thanks Nate. I'll get a printout from the shop this week. Every time I've talked to them about it, they've looked it up and I hear them reading through the numbers and then saying...'yeah that should be fine on 89 octane'. And I'm like 'I'm not a smart man, but I know what pinging is'. Certainly...

Thanks Beanhead That makes sense. I'll order the AF meter and check the #1 cyl for tdc against the balancer. Sounds like I should get a jet kit and see what is in there now and try one bigger, just to see what that does. I really like the idea of an AF meter so that should be fun. Ultimately...

Hey Slap Stick Good Question. 78's primary and secondary are what I'm reading online, but I don't have the part number of my exact carb in hand....I'm realizing that knowing that a/f number will be really valuable. One question and this might be totally unanswerable: would running hotter on...

THX lewtot184 I did notice that I was getting more total than I should have (with the plate on the 14 slot) by 1 or 2 degrees and right then started wondering about exactly how accurate the plate was!! I'm planning on an EFI setup sometime so I figure the old style distributor will be replaced...

Thanks Curiousyellow71 The machine shop read off some of the numbers to me on the phone and I know the effective CR was in the 7's based on their test before sending it out. Ben

Thx Don. I'll do that and report back.

THANK YOU Kerndog for all that info!! The point about pistons Vs Head gasket thickness for comp. ration alternation is very interesting. I'm basically stuck with the setup the shop built EXCEPT one of the head gaskets is leaking coolant a tiny bit so they need to change that for me, so I was...

Thx Khryslerkid, Not totally sure what all the machine shop did to the heads, but they're the stock ones from 73. I believe they cleaned up the exhaust ports as those had some big restriction for NOX emissions stuff.. The shop did say I should be able to run on 89, but I haven't bothered...

Thx 4mulas, The machine shop tells me they tested everything before sending it to the shop for install. I am not familiar with what leads to a damper shifting, but the machine shop suggested that it's not likely on a new build (which I just put down in the notes as one more thing to learn...

I've got a 440 that was rebuilt to a good street blueprint by my local shop, Action Machine in Seattle. They say it should be 9.35:1 and run fine even on mid grade gas. The problem is that I've had to limit my total advance to not more than about 26 to keep from pinging. I've danced around the...

OK! Quick shout out to Summit, ordered on saturday, ground shipped sunday, and I got the pressure gauge today. The Readings make NO sense!! The passenger side reads about 600psi, that's the one that locks up easily. The drivers side reads 1500psi. So we've got low pressure on the side that I...

Thanks Robby. I ordered the pressure gauge so I'll have that later this week. As far as piston movement, would you just pull the caliper and observe it while someone presses the pedal? When i changed the pads last time, both Pistons compressed back in as expected, smoothly. Thanks again for...
