ANY Q'S ?
ANY TAKERS?
thanks for reading my post.

I'm not familiar with the 346 iron heads, what did they come on?
So a guess hmmm..... I say between 700-850 horsepower! Is that a large enough range for yah?:D

[blownzoom440]

thanks for reading my post!346 heads came on 1974/76 big block mopars and had hardened seats .your guess range is in my target for the build.:rolleyes:
i hope for the top end of it.i know people post how much will it make all the time.sorry if it bothers anyone!you have a great site here!
THANKS!

That's a rather wide range you got there. But if this is your first build like this fair enough, you just don't know what to expect. I was running late the day I ran my engine on the dyno a few weeks ago, didn't have time to post an estimate. But I had told Neil at SDPM what I thought it would make. I was within 12 hp. Not bad out of 935 ponies 1.2% close enough.:D
Good luck with it. Hopefully you will hit your upper number. And for those who don't like people posting numbers, they can always read another thread, but I think most people enjoy the numbers.

thanks!
i was joking saying it was in my range.the engine has been togather for 3yrs but with a smaller cam .541/.559 113lsa solid lifter/flat tappit.the springs were way too weak floating thge valves at 80lbs seat:eek: with 8lbs of boost it ran ok but with more psi it did not go faster so i changed to a roller with more spring psi[240 seat/600 at .650 lift.] and lift,duration.i made about 700hp with 8 lbs no IC 3% UD.
thanks for your interest!

[pw_Tony]

I had some heads ported my Larry Holt, who is pretty familiar with 440 cast heads. Had some 2.19in and flow benched for "max" cfm(yah right).
But anyway those were 906 casting, and the max they flowed was 255CFM at .550 lift. Which is not very much. I know the Eldebrock heads flow cast at 292cfm at .600

[Sleeper CP]

Didn't really notice the :rolleyes: face there. Should have re-read.
But after reading what you did before I would guess you would be happy with 825+?

here is a pic of the engine.

sorry here is with the IC.

i stuck with my 346 heads for $ reasons.it was 15yrs ago i had them done porting 1000$myles engineering and now champion racing engines in cleveland OH.i put the $ in the SC because i always wanted 1 and will accept whatever the heads will give.the block,heads are o-ringed.

oh man a slowpar lol.. sorry I had to. Mopar guys are far and few between these days it seems. Motor looks good, I bet it will make 820 fwhp.

It only bothers people when someone posts dyno info about their car on this
***boat website.:mad: :idea:

LMAO. That's what people used to tell me until their BBC got beat by my small block!:jawdrop:

[moparjet]

hope it makes good power zoom....i know my mopar woke right with the blower...we almost have the same motor.....the jpc tells me 607hp at 5900rpm...good luck at the dyno

what is a JPC?
i have dynosim[ engine builder.]
it may be dyno info for a car but may benefit someone building a like engine for a boat.sorry it offends some of you.

[blownzoom440]

if it will make someone feel better here is a 454 TT IC 11lbs above the IC made 700hp.scott koffel ran this engine 2 weeks ago there was 2 of the same for the boat.http://s27.photobucket.com/albums/c192/blownzoom440/?action=view&current=Jul17_13.jpg

JPC IS A JET PUMP CALCULATOR....ITS ONLY A ESTIMATE BASED ON THE JET PUMP IN A BOAT,RPM VS. SPEED....NOT REAL ACCURATE....THE DESK TOP DYNO SHOWED ABOUT 625HP FOR MY MOTOR WITH BASIC INFO

[MACHINEHEAD]

740Hp/6200 at flywheel
655Hp/6000 at the wheels

[Blown 472]

726 hp at the crank, Why not a set of eddys?
You put alum mains in it? my 440 at 666hp pounded number four main until it fit the crank and fell out when I pulled the cap, this after it spun number two rod, watch your oil pressure after you get some miles on it, if it starts to change drop the pan and check the mains, also make sure you run good gas in it and keep it out of detonation and mine seemed to be happy at 30 degrees total with iron heads and 7.7 to 1.

Yes very true. I have never experienced any oiling problems, but watching the guage is very good!
Factory 440 heads have crappy combustion chambers, very inefficient and detonation prone. If you set the Eldy heads next to factory you could see how much farther away the spark plug is away, and that shallow open chamber area doesn't help.
But then again, run what you brung! Spending more money sucks!

[blownzoom440]

thanks all for your input !i have made 700 with 8lbs so to me anything under 800hp i will be thinking what is wrong.i will use c-112 as Mr Koffel has a few barrels of it.i know a good tuneup is key to keeping things togather.i have had good luck with 34* timing so i will start at 30* this time.i use a MSD 7-AL2 and pro coil.

[blownzoom440]

i will let you all know how things turn out.THANKS!
i am off to pit crew on the LAKE ERIE MONSTER at the night under fire at norwalk ohio.here is a video from 2 weeks ago.

Hey, did they ever take any pics of the single four intake that they have on that car?

[blownzoom440]

yes i have some pics of it!i will bring them later for you!
we pushed out the head gasket in the 1st rnd of racing in the finish line and dropped a valve in the engine so we were done.

blower intake pics!:)

[DEL51]

That don't look right, but I know it is. I like your big wedge with a blower. Holleys look good but I do not agree with the restraints. Lose them and it looks great. Just my opinion, but I am a mopar and FE fan.

[pw_Tony]

Here's my pops, bought it with a milled down tunnel ram

That 4 barrel one looks crazy

[blownzoom440]

we were going to try the 4bbl intake this yr but thay are trying to find why #8 cylinder pushes out the head gasket on the top end of the track.the 2nd time the engine was sent for welding.[aluminum KB block]
here is inside the intake.

[Blown 472]

Is that the opening? what opening does the bottom of the blower have? and are you injecting at the hat? can you just inject at the hat with that set up or do you have to have port nozzles? reason I am asking is I would love to do that to a small block as no one makes a blower intake worth a shit for one.

[blownzoom440]

1)yes that is the opening from the top view.
2)the supercharger is a mert littlefield 14-71 i am pritty sure it has the delta opening at the bottom.
3)we are injecting at the hat and runners.
4)i think it could all be done at the hat but the port nozzles alow tuning of each port/cylinder.
i understand about the sb intake.there is an article at victorylibrary.com in the tec paper section about building your own blower intake from a 4bbl intake.

[Blown 472]

Did you dyno your motta?

[blownzoom440]

we did a test pull last night.
WELL!
at 3200 she made 841TQ/531hp
max TQ 4400 896 .hp at 5500 and pulling 854!and no intercooler![no water in it.]the intake temp was 260*.i cant wait to get some water in it.i am very happy with the results !

we will do final pulls on monday.

[MACHINEHEAD]

Way off. Heads are way better than the numbers you posted would suggest. Stress on the bottom end. Your thoughts. Yikes! Just plain awsome Nice Job

[blownzoom440]

RESULTS WITH THE NTERCOOLER.
with only running water in the intercooler from the house hose the temps went from 260* to 130* in the intake. the boost read 14lbs.
at 6000 rpm the hp is 996
3200 rpm the TQ is 931
with max TQ at4000 at 983 ft,lbs
we tried to detune it with 10% less OD,NOT!
12lbs of boost 114* intake temp
it made 989hp at 6000
893 TQ at 3200
932 TQ at 4300rpm
UNBELIEVEABLE.
GOT BOOST! i bow to the hp gods!

[Sleeper CP]

Wow!!!!! RWHP?
Those heads must flow a lot better than you thought, what's up, why so far off on the quess? Is the lower end going to live with that much power?
Good...no Great #'s.

[blownzoom440]

that is crank hp.
i was off on my guess due to valve float i had last yr and she would just not go faster at the track.no the lower end will not live with that much hp.i need to detune it to about 800hp and hope to get a newer stronger block next yr..
i am using a stock 1967 440 chrysler block[no hardblock] with a main girdle 3/8 thick and stock main caps.4340 crank with stock stroke,eagle h-beam rods,wiseco blower pistons 8.8cr,hellfire rings.
thanks again.any questions i will try to answer.

[Blown 472]

stock iron caps?

[pw_Tony]

Wow that's very impressive!
Do you know what kind of flow numbers your heads are seeing? I had a pair ported and flowed, and they were seeing 255cfm@.600lift. THey were 2.19 intake valves, and ported by Larry's Speed Specialist in SD, they were 906 heads

my heads flowed 280/180 at .600 2.14/1.80 valves,346 heads.

[blownzoom440]

Sleeper CP i am going to detune it to 800hp or so.i was not sure how much hp i would get when i put it togather.max i was supose to be 900hp to expect.i put out around 700 for the past 3 yrs but with valve float.i was my first blower build and was not sure what was going on.i did not dyno it then either.
