....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

650/620

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

Thanks,Cab..Gary..and Mike! Gary,you really think it'll make those numbers?! I NEVER would have guessed it to be that high....but, Sean Meyer...formerly from Best Machine,estimated around 660-670 horsepower! We'll find out shortly! Gary..on your chassis dyno,my peak horsepower was made at 6,000rpm's. With the increased air flow...what's your guess on the new peak rpm???....63-6500? Thanks guys!

Hi Randy! Torque per Cab's suggestion and you will have no problems. I will go with Shawn's numbers. He was spot-on with mine .

Randy

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

Mick...Ron who?...Ron Neis(383 Man) Yes..he has the size advantage,with a stroker! I'm thinking with my better air flow,the shift points will be higher than the 62-6500rpm that I was using. Even at 6500...that cam was still pulling pretty strongly! My goal is to run consisted high-10's..on pump gas..and still be relatively streetable!

Randy you are going to have an awesome running car. You might be faster then me unless I can get back to the track sometime and try a few things. I think I have 10.50's in mine with more tuning and more carb but I dont know when I will get back to the track. I used the 4.15 crank for 493 cubes with 10.6 comp and I also use a Dwayne Porter speced flat tappet cam thats close to yours but a tad more. The 63 weighs just over 3700 with me in it. Your car ran great before so I wont be surprised to see you run 10.70's or better. Good luck my friend and keep us posted on that cool machines progress. Ron

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.

Thanks,Mike! To play it safe I think I'll go to 80 ft. lbs...using the ARP Moly Lube. As far as horsepower goes...I haven't a clue! If Dwayne estimates yours to be 620,you're probably correct with 600 on mine! We will find out shortly!

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

Thanks,Mike! Make sure you give me a heads-up for the dyno! I want to be there! Sean did degree the cam..got the same 105cl my friend Mike and I got,when we installed it back in 2008. Mick...what lube did ya' use on the fasteners,with the 75ft.lb. torque value??? And you mentioned using shims??? Never heard of using shims on a head gasket before!

If you have ARP's bolts, use 65#s w/ moly lube per their specs.

I'd guess it's a 580-600 HP combination, depending upon how dialed in you can get it. Those 650+ HP guess-timates must come from some pretty happy dynos.

The car should be capable of dipping into the high 10s w/ decent 60-ft. times, but I don't recall how well it hooked before. When you did the carb testing last summer, it seemed like traction was a big problem at the track you ran at.

Randy, 80# is too high. Check your PMs

Hi,Brad! I'm thinkin' 600 hp or thereabouts,as well! Anything MORE is just a bonus...and a SURPRISE! I also believe 10.70's-10.80's is attainable....with decent traction! I was averaging 1.54-1.56 short times,the day I was testing the 2 carbs. It was a HOT day as well! Also...Ubly's starting line prep is pretty much nonexistent....unless they have a racing event scheduled,but NOT for just a t&t session,which it was the day I tested there. If I have traction troubles when I get the car back together,and to the track....it's ladder bar...or 4-link time! I've already discussed the possibilities with Raff(P-Body) and Randy Johnson(Dartin)
