Dart Iron Eagle question
 

hi,
anyone here with Dart Iron Eagle Platinum heads with 200cc intake runners and 64cc ?
i have this heads on my El-Camino engine:
GM Performance Parts 350cui block 12486041
DART IRON EAGLE Platinum heads 200cc intake runners
Professional Products Air-gap High-rise Intake

COMP CAMS XE274
COMP CAMS Valve springs, retainers, valvelocks
COMP CAMS Push rods chrome-moly
CLOYES TRUE Roller Timing Set
MSD 6T ignition system
MSD Billet Distributor
MSD 8,5mm spark plug wire-set
Splitfire spark plugs
Flow-kooler waterpump
Meeling Hi-volume oil-pump
engine-oil cooler HD
Fluidampr Harmonic balancer
RAM-AIR BOX

last summer i testet the Camino on dyno: 330rwhp
thats ok for me, but now i have a problem
the Oldsmobile from my wife is ready and i feel now, the engine in the Olds runs better ....and FASTER ! :willy:
i build this engine for the olds with the same block, camshaft and so on. the one and only difference are the Vortec heads.

any idea ?

ah, i see...many engine specialist here:rolleyes:
this is just a simply question about heads, the vortecs better than Dart ? the Dart heads the right choice on my engine ?

I think the Vortecs are better out of the box than the Darts. Fully ported would be a different deal in my opinion.

thanks jody. what do you think can i do ?
heads replacement ? hmm, no idea:_paranoid
have you a good idea to optimize my engine with this heads ?
bigger camshaft for higher rpm ?
i read some tech articles in CHP, 350 chevy engine with this dart heads.
380 - 420hp with differnt cams and carbs and intakes:wow:

i run the dart heads on one of my 69s they like a bigger cam

give me an idea...how big:question:

i am running a 300 310 duration with 630 lift 106 lobe seperation with mine verry responsive and believe it or not its not bad on the street

aah, you have the 1.550'' Springs. what is your engines rpm range ?

yes 1.550 springs rpm is about 3500 up and it pulls like a mother untill you let out of it this car is basically a street racer though . i wouldnt want to run a automatic with this combo on the street . from what i can tell i would change your cam and intake. i have allways had good luck with the victor jr and i allways run crane cams no exceptions. i have ran comps stuff befor and had verrrrrrrry bad luck with it. motors were allways down on power . but others like comp . as far as cam call crane. comp and a few others and see what they recomend

I like the cylinder heads more so than the carb choice. And your cam might be a bit small. But before changing anything, I would confirm that you have adequate compression and then find a shop with a Lambda meter to confirm that your carburetor is keeping up with the rest of the combination. Alternatively, you can purchase a Lambda Meter here.
