This is all I charged you for on the head studs, if I charge $.01 higher then that price i'm told i'm overcharging.

So I used ARP 8mm bolts on the top row, you would have to stretch the 1/2" head studs to touch those bolts.
We've gone 7.60 with 8mm bolts on the top row so I figured that would be good enough for you?

My only issue with the 1/2" head studs is there a little taller or maybe not as deep in the block so I had to clearance the turbo header flange. Small price to pay for the job they do.

I've got about 100 miles on my new 390, I've done a couple 5lb 4400rpm pulls checking fueling and timing, checking for leaks, loose fastners, etc.
no.1 I'm really surprised how much faster this engine revs compared to the 408 I took out.
no.2 After about 1hr of run time, idling, driving, changing oil and stuff like that you could noticable see the difference in how well the engine sealed up. I have breathers on the valve covers so it's easy to tell how much blow by there is or isn't.
no.3 I'm not going to go on about how great the engine is or compare AES to other builders, I'm just going to say that when you buy a shortblock and install it and you have that nervous feeling as your getting ready to fire it? The engine fired and ran exactly as you hope for when your getting ready to turn the key.

I had a guy who "owned a shop" buy an engine from us, asked "is this engine good for 30psi?" I said I don't rate engines by boost, I think power level is more accurate. So he tried to rephrase and to ask once again "will it be ok at 30psi though?"
Didn't even know which head unit he was going to use.Whats the answer, far as I know 1200hp when the trouble starts, with 4 bolt heads. No matter how many O rings it has. With a blower i'm sure it would be around 900rwhp area to make 1200hp, you have drivetrain loss, and loss in turning the blower.

Finally someone said it, boost is a measurement of restriction. Sure it will correlate to a cfm number, but that is unique to every compressor map.

Well... the 390 you built me, pulled ~1150RWHP on the dyno.. and yesterday it ran an 9.40 @ 151.9mph (over 3800lbs).... I say its a good engine!!!

appreciate the pics. I am hoping that they will send me a few of mine soon to add to my build thread. said they needed to wash it etc.....waiting now.........I wonder how the 317's will compare the the PRC's. I hear the 317's are a great head. I hope my heads are not just a gimmick. Guess if i had some flow charts I could fine out.....plus, I am not sure if 317's have a .750+ deck. im doing that plus the 1/2 inch studs to keep em down. I am hoping for 750-800 from my lil D1. should hopefully be a safe hp for this setup.
