....using 10w30 on the threads,and under the bolt flange? Edelbrock's torque spec for my Performer RPM's bolted to a stock block. Just wondering if anyone was using a different value...and WHY? Finally getting some time to screw my 440 back together...and get it dynoed at St. Clair Engine,in Armada. Any "educated" guesses on HP..and torque? The block is a .045 over 440. Newly cnc-ported RPM's by Jeff@Modern,which flow 316cfm @.600 on the intake,220cfm on the exhaust,221cfm at mid-lift(.300)160cfm on the exhaust.The cam is a Dwayne Porter-speced Comp SQ solid flat tappet. Specs are 262/266 @ .050 duration...579/585 lift,ground on a 104 LSA,and degreed to 105. Using 1.6 Crane rockers,lift is approx. .594/.600,deducting .020 lash settings. I will be gasket-matching my Mopar M-1 single plane intake,to match the larger intake windows on the heads. Carburetor is a Biggs 950HP,headers are 2" TTI's. Mopar Performance electronic distributor(modified for full mechanical)and a MSD 6AL box. Thanks in advance for your responses! BTW..the motor will be going into this old green car! Randy B.

Randy, that is the specs. I use on my motors with Eddy RPM heads and stock or ARP bolts,I tighten them up(all the bolts or studs on one side) in three increments,25 lbs first, 50 lbs and then 70 lbs, I do use 75 lbs for final torque on the studs, I think I have the instruction sheet on the clipboard in the shop and look at it each time before, to torque any parts in the motor, starting so my memory may be off a little on the studs

That sounds almost the same engine as mine, except i run the mopar.590 cam and i'm at around 12.7.1 comp. I reckon mine is around 600 hp, unless you've got higher comp, i wouldn't have thought yours would make anymore power than mine. Mick

Randy you may not get any more higher peak but make it broader. I cheated on the guess. I went to your file on the dyno and and about what it may pick up. I have seen where ther was only 10 hp increase but the power band was now so broad that it was a monster. So dont be too dissapoint if it dosent make alot more peak,but hopefully more alaround power!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Randy..in NO way am I doubting Shawn on his numbers! Like yourself,if I get what he predicts..I'll be a VERY HAPPY camper! I'm thinking that going with aluminum main caps,held in by ARP studs,aftermarket K-1 H-Beam rods,having the cylinders plate-honed,and the piston skirts coated,not only gives the bottom end more strength....but lessens the friction of the rotating assembly..adding additional horsepower!..how much is debateable. I know one thing....I will no longer be nervous to twist it to 6500-7000 rpm...if my peak numbers dictate it! Gary...broader torque curve,and MORE all-around power is a GOOD thing,for sure! THANKS for your input!

I wouldn't have thought that cam would like much more than 6500. I shift between 6000-6200 and go through the finish line at 6500. I would guess at 10.80-90. Ron's car looks a similar weight to yours and he's gone 10.74 but with 50 more cubes. Good luck, what is your et goal Randy ? Mick

Randy, it is confusing about the head bolt torque for the eddys. Eddy states 70 FT.LBS The ARP bolts that come with the heads state. 65 FT.LBS with Arp Moly or 85 FT.LBS with 30# oil. And 60 FT.LBS with Arp Moly and Aluminum heads. They dont suggest a Torque value with oil and Aluminum heads. But heres what I know. When these heads first came out, alotof people and builders were using the 70# number and having some head gasket issues. The one shop stated they bumped it up to 75# and the issues stopped. I myself wouldnt use anything less then 75 FT. LBS. Especially if your going to be useing the soft 8519pt gaskets. Anywhere between 75 and 80 FT.LBS should be good IMO for you. At 70 FT. LBS you will be risking a gasket failure. Id guess your HP around 600+ or so. That cam isnt that big and niether is your comp. But she will be a runner. With more cam 272@.050 and comp 12.5 and same heads, Dwayne estimated my HP around 620 on his dyno. Im thinking thats abit low, Im hoping for 650.

Randy, I got my heads from Jeff around 3 yrs ago and i torqued mine to 75 lbs on my old motor and the one i use now, i used shims on the last one and felpro on this and haven't had a problem yet. Mick
