what modifications are you referring to
the custom work i paid for, i dont have the receipt here to quote exactly, but he hand ported, re-seat, higher lift clearance somehow, stuff, things, money spent way over 1 year ago..

although i have seen a few morons slap this cam in a stock 06-08 car engines on youtube, it ran worse than mine, and i have a missfire, but it ran.
the camshaft is made for 3rd gen hemi non-vvt motors, so pre-eagle heads are expected, there are no special notes about needing head work.

The upgraded springs are recommended and allow higher redline from 6800 up to 7500 RPM.

keep in mind that there are other factors besides just spring pressure which dictate the safe rpm capability of a particular engine.

yeah i also had the block line-bored, while being fully bolted up at full torque.
forged crank ect.
balanced assembly

not that i plan on red-lining it at 7500... not with this tranny at least

I was wondering, can those heads handle .632 without modifications?
Eagle out of the box and on to the engine, lift wise .625 (+/-) .01 depends on how well the Guides are set, any cam over .600 we check and machine down the Guides. Power wise 392ci, 550HP is easily attenable with off the shelf Eagles.
Flow wise, the Best thing about the Stock G3 hemi heads is they do not stall ,(more lift, less HP).

Eagle head : Exhaust the port flows good as is , the big obstruction is the 1.575 valve size, to a lesser extent the 5/16(.311) stem., 1.60 is the more commonly available valve, and the Eagles LOVE it , it's hard to find "big exhaust" vales for the Eagle head, the bigger the exhaust valve(up to 1.625) the better,1.625 and smooth out the port to a true D-shape and WOW completely different head...problem is only none custom 1.625 out there is Ferrea F1173P it's .030 longer then stock...and it's not budget friendly.
Manley Custom valve blank 11207 will fit the bill, but it's a custom order and you need to have your specs for seat width and all the other specs....slightly budget friendly.
On the intake side, stock bore and stroke 5.7(345CI) just a simple port match and stock 2.05s will carry you up to 500-525Hp(1.52hp/CI), 392+ CI , 2.05 valve and stock port will go 1.4(540-550)
the Best thing about the Stock G3 hemi heads is they do not stall ,(more lift, less HP).
Keep in mind you only need 300 CFM to make 570-600 Hp between 6400-7700 RPM, cubic inch dependent , the more CI the lower the RPM needed to hit 570, , Wedge engines need the exhaust side/Port to be 80% intake flow to hit those #s , Hemi by nature only needs 65% , the higher the better.

Prime example ,
Yesterday we were at Maple Grove, Truck is a 2005 RCSB 4x2. weighs 4450 with driver,
390.7CI (3.9185 X 4.05 )
Eagle heads: Intake were left as cast, only mod was Port matched to intake, 2.125X6MM Valve(guide changed for 6mm stem) Exhaust side has the aforementioned Ferrea F1173P exhaust valve(1.625), port it's self was mirror polished and matched to the cheep a$$ Ebay headers, (1&7/8 tube) Holley Hi-Ram, HellCat TB .
Build=Engine
Pistons , Icon IC653C-0015 Pisons 8.7cc dome
Crankshaft , Molnar 345-4.05JAF6 (2.0 crank pin)
Rods ,Eagle CRS-6125SO3D
Timing Chain , Progear PG4600
Smith bro Push rods, Custom order.
Valve springs , PSI LS1514 installed at 1.90
Oil Pan Milodon 31032
Damper , ATI 918433 5% ud , ( Truck timing cover is being used)
Static Compression is 12.30(had to use a .070 Gasket to get static below 13 to 1)
Block was Honed to 9.185, and decked to a true 9.252, some oil passage work.
ECU is OEM
Trans is a 46RH ,4500k stall, revers shift pattern
Build Truck=
Rhodes Fuel tank mounted in spar tire location
9.25 Rear, 4.56 gears
True 3 inch Duels aero3030 Mufflers , exhaust dumps under bed.
Stock Ride height,
Stock rear springs minus over load spring
Crappy A$$ traction bars(Lake wood slappers....hence the 2.125 60ft)
No Ac or components,
Radiator , Cheep a$$ ebay , but it's centered up on the support.
Wheels on all for corners were stock Rumble Bee 20s, rear tires were Nito555 315/35R20 fronts were Nitto NT420V 265/50R20

93oct , truck was driven an hour both ways to the track,
MPH @ 4450 = 570HP ,(1.46hp/ci)
MPH @ 4450= 687HP,(1.76hp/ci)
60ft time = 200HP.
Air Temp Was 45F , IAT was 90F Baro was14.7
Once this wreck is sorted out there's no reason it shouldn't run a minimum 10.90 weighing in at 4450(with driver)
PUMP 93 oct. in the same conditions, it's an 11.15 @ this weight in 80F temps.........on PUMP gas.

Just to be clear, what heads are you calling "eagle"?
Im running the 2008 heads. ( pre-eagle from what i read)
2009+ was the "eagle engine" (reference)

Oh. right..
Odd thing came up, I ordered the Trans-Dapt dual filter relocation kit.
everybody told me the engine threads are 22mmx1.5
summit was out of stock (part fits my engine)
i purchased from Tdot - they ARGUE with me it does not fit my truck. i insist they send it. NO REFUNDS!!! they say

My red 2008 ram - OG engine -22mmx1.5
My blue loaner 2008 ram - 22mmx1.5
the donor 2008 ram engine, the "build engine".... 3/4-16 WTF??!?!?!

had a buddy at machine shop turn me a new threaded insert to adapt the trans-dapt

Oil filter thread changed?
ran into one engine sensor plug change too... IAT or MAP, i forget, have to look at the engine to remember but its 500 km away rite now

Actually the HRT3 cam were designed for the 6.1/6.4 Heads , the thought behind it was to be a modern version of the VVT274 cam and a replacement for the old 6.1 273(112-502-11) cam, which we limited lift to 547/550 because we new the 5.7 guys would buy them, (03-08 5.7s) and the 5.7 head was limited to .560 lift with out spending a lot of money on.
112-252-11 , was designed to be used in the early 5.7s with stock Operating system(tune) in mind.
201-700-17 was designed for the VVT 5.7s , the idea was to give the R/T boys some real bang for the buck with out any other Mods and meeting Emissions
201-335-17 , thought behind that cam originally was for the Stock Eagle head Max effort guys who only wanted to change a cam and Valve springs.....but during testing with Turbo's it made the most power of all the VVT cams

the cams that have more then 10* degree split at .050 are the ones we designed with the 5.7 Eagle head in mind, the Eagle head in stock form needs more exhaust help then any of the other OEM heads.

I've run in to that it's Pain in the A$$ most of the 07(s) and down have 3/4 while 08 was kind of a transition year.

ahh... i have the 112-305-11 hrt stage 3 - link
and i basically pieced together this master kit link - only difference is my push rods are Manley not CC (stock issues)

Sooooooooooo In light of finding out Tristyn is using 03-08 heads..... F-no those heads need a good bit of work , which it sounds like he's had it done.

Knowing that these are Not Eagle( I'm not sure why but I thought you went Eagle)
The HRT3 cams makes more bottom end Tq in the older heads then it will in the Eagle,......03-08 smaller ports = higher velocity.
Basically power "band" is about 1200 RPMs lower with the older 5.7 heads over the Eagle/6.1/6.4 heads

I'm liking the choice more now,

As for the HI-ram ? are you using spacers to deal with the miss match ports ?

no spacer. go back to page 8 for photos. we hand port-matched the heads to the intake. they are a set now.

Do you remember Valve sizes ?
no.. stuff was done for over $2000, over a year and a half ago.
receipt is with my truck.

CompCams does not warn of needing work done on heads...
but probably recommended.

"just a custom tune" lol

i cant wait to see how many pushrods are bent later today.

its funny, this f-up made me smile, not only because "i was right", but this was the 1 thing we forgot about.
Once we remembered this part was sub-par and needed the upgrade, I had this feeling of "completeness".
I knew it was NOW done. or.. done enough to get on the dyno and start driving again.

the older heads start to lose Rocker to valve tip contact once you get over .575/.585 lift, it's why the 6.1 and pre Eagle head burn up rocker tips, chip valve stems., Lash caps save the day, or you can shim up the rocker shafts, Banana grooving the shafts also helps , by keeping the rocker tip and valve stem constantly wet with oil.

Well... Dan went to swap the pushrods.
One fell out. #3, theres the misfire
all others are .030 short. theres the valvetrain noise.
none are bent

New ones... are the wrong ones. they are for the VVT and are 3/8 longer than original.
cant find a set of non-vvt ATM....

any thoughts?

i found some adjustable pushrods

are these a thing? or a dumb thing?
im calling in the morning to see about their stock on their CompCams set...
the compCams set ( same set supposed to be in the HRT 3 master kit) are .050 &.075 longer than mopar OEM length
but cc website says "engineered to provide optimal preload for late-model HEMI applications when using performance camshafts " maybe thats the extra length?
