The pushrod looks like its rubbing the bore on the head?

This block is .030. Some 1008 on the way. I've got some cometic's for another build. Learning is getting more expensive...

ARP lubricant was used and the heads were torqued in three steps. Threads are clean too.

1008's on the way. 3.91:1 with a 2.47 (833) 1st is the best combination I've run so far. Had higher expectations for the latest SFT ect. ect. Thanks for the feedback.

Several were not "snapping off" when loosened.

I'll post up more pics. Conversation with ARP tech this morning, then the supervisor called me back. Supervisor stated: "if you have a fire ring that thick, .053, bring it up to torque, then back them off, 1/16 and bring torque back up. The fire ring needs to get crushed as much as possible...

The head bolts are not bottoming out, they're actually .300" shorter.

Checked the ARP against the OEM. The ARP's are .300" shorter than OEM. I ran them up to 95ft# per the instructions.

any way to address the issue? Open chamber 308 castings.

Heads were decked. I don’t believe the block was.

Thank you. I’m at 4700’ and the air at the track went from 6200’-about 7000 by the last pass. I’m not sold on the arp head bolts.

Vacuum is Hooke up above the throttle blades on the metering block.

I agree with you. I’m not convinced that the ARP bolts are working. They give inconsistent torque readings as their loading.

The set up is still running the vacuum advance if that helps.

I do not see a tan ring on the base of the porcelain. No idea what I should be looking at though.

No doubt. I'm wondering if they needed retorquing? I've got some Felpro's for this go round...

I’m not sure when total timing is achieved. The oem distributor was recurved by a shop with a sunnen machine. The compression is 1.5pts higher than when I requested the recurve.initial timing is 16*

Quench area is -.010-.015 with the gasket and chamber it’s most likely.1+ oem open chamber iron heads. 91 non ethanol fuel.

Quench is non existent, as I’m running 308 castings with Ross -11cc I believe. Cylinder pressure is 180+ total timing 36*. I’m not versed in heat range. The plugs looked great. Any suggestions on plug heat range would be appreciated.

Gentleman, I’m running arp head bolts with roughly 11:1 compression at 4700’. Made four passes Saturday at 6200’ adjusted altitude and blew head gaskets on both banks. I bought them from Holley, .053 compressed I believe. Looking for recommendations.

Thank you.

MSD Power Grid controller HELP! I'm assembling a car I bough as a roller and I'm new to the MSD system and have a mechanical advance distributor. Can the controller be programed to work with this, or..? Thank you!

I ran a four speed for 35 years, and a n exposed transfer slot is a pain in the *** off the light…

Exactly!
