What's considered "safe" with arp head bolts?

The combo is a 408 with ls3 heads and around 10.3ish compression. Pump 93 with 10 and 18 meth jets.

 

6 psi.

 

I think you would be fine with ARP bolts, they won't stretch the way the TTY bolts do. Should hold at least 10-15PSI.

I think its more about your tune up than anything.

 

Im wanting 18-20. Too much? No point in having a 3.6 blower and not letting it breathe.

Im thinking dominator efi or having it dyno tuned with something safe. It currently has a 2010+ camaro ecm so the no ve table thing is weird.

 

Swap to studs call it a day crank it to 25 psi and hold on

 

i think 25 would require a custom pulley. A 3" is supposedly 20# on a 7.0. Would that boost be higher on a 408?

 

Oh, this is supposed to be my street toy. It might see the track once...maybe

 

You gotta use Efilive to get the VE table. Hpt's version is not ready yet

 

The VE won't be too difficult to tune since I'm assuming it doesnt have VVT. The later revisions of HPT have a coefficient to VE generator built into the editor now. You still running a maf? As for the bolts I think 20psi is pushing it. I couldn't say for sure though since I've only run the bolts once and swapped them out for studs before leaning on it.

 

Many forget, I had arp bolts in my last motor. saw 23 psi from a d1sc and did not push. However, don't let that fool you. Several months before that, I pushed coolant on 14 psi bad enough that there was a puddle of water on the trailer under the motor and a water stain trail down the side of the block. See if I can find a pic..........
