1050 dominator on olds

[PANTHERJET]

I am thinking of putting a new 1050 dominator or 950 4150 holley on my olds 461. The engine is built with all the oiling issue fixed about 10.5:1 compression comp 292h cam E casting heads with port and polish three angle job, victor high rise manifold rewarder ot headers and mallory igniton. I am currentley running a edelbrock 750 that has had the choke horn milled of and been set up to where it seems to run best but acts like it not getting full potential. Also the set up is in a 20 6 elliminator with a panter max rpm i see is 5600 any body out there that with any info on running the two mentioned carbs if its to much would help

What parts are in that Olds? Unless you have a 'lightened' rotating assembly I wouldn't try for any more RPM than that. If the pump is tight, that puts you around 475hp.

I'm running a 4150 950 cfm, runs good on my 454 stock bottom. I would like to try an 850 and see if it runs better, I'm a little rich but she has good mid range and top end.

Might I add that his boat runs pedal to wood all day looong!!!! It never skips a beat;) I have rode in it and it runs hard and good....

the rods are stock forged with oil reliefs cut in them like monello said the crank is nodular cross drilled the main have studs with mondellos cap kit the piston are forged then the hole assebley was balanced

If your running 5600r's with an olds your engine builder did dome serious work for ya! Alot of olds wont run like that with minimal mods. Congrats on the setup, what kind of speeds does she run?

the main reson i ask is i have a horible flat spot at 4200 rpm and then it clears up . also i run it pretty much wot all day it just seems like a should have some throtle left .

[77charger]

Dont think it will do you anygood but waste money.You will need more cam also to get the most of a 1050.Unless you plan on reving past 6k stay with an 850

[PANTHERJET]

I Built The Motor With Some Help From Mondellos And My Balance Guy. The Hole Things Is Speced Out To The Nuts It Holds Together Fine To 6000 If I Play With The Ride Plate But I Just Lose Speed Then

[PANTHERJET]

77 Charger Do You Think The 850 4150 Would Be A Good Choice

[malcolm]

Are they TRWs or something fancier?

[PANTHERJET]

They Are Special Orders From Mondellos I Had Two Sets Laying Around One Set Of Trws And One Arias I Burnt Up One Motor In 15 Hours And Builth The Second One Dont Rember Which One Got Burnt

[malcolm]

Olds don't like much past 5500 with stock weight pistons/rods. Just be carefull up there. Your kinda stuck with the B range Panther impeller, maybe one of these guys will come out with an A for them one day.

I Am Working On Building A Blown 455 Olds Kind Of Just Collecting Parts Put Am Tossing My Hands In The Air If I Should Or Start Fresh And Build Chevy Wat Do You Think

[malcolm]

Don't get me wrong, I like the Olds motors, but if you want to go past 6000 (blown or not) I'd suggest a Chevy (or even a Ford) ;)

[PANTHERJET]

Thanks For The Input

[malcolm]

I'm building a 455 right now. A little smaller cam than yours, just a 280, but forged pistons. I have a 454 Chevy waiting in the wings to build when I'm ready for more power. :)

I think it will be fine i have seen 850s on motors makin some good power.In drag cars.More than enough carb IMO.

[Jeanyus]

I would read this
http://www.summitracing.com/streetandstrip/charts_guides/charts_carb.htm
Acording to the formula your engine would flow746 CFM at 5600 RPM, if its Volumetric Efficiency was 100 %. You VE is probably about 85 %, which puts your actual CFM at about 634.
If you have a flat spot, my guess would be your secondairies are opening to soon. Edelbrock website should give you info on how to fix that problem.
I had a 454 bored out to 468, it ran perfect with an 850. I wouldent go bigger than an 850.
A 1050 won't fit your intake manifold without an adapter.

Now thats a great pic !!! :cool:

[PANTHERJET]

i was talking to mondellos and they told me to dump the edlebrock and put a holley on and i got to thinking if i can run dual 750 on a tunnel ram on the same engine why not run one bigger on the victor and mabye that would help and malcom if you need any parts i have a few spares laying around

[malcolm]

Taylorman went from a dual quad to a victor and was really happy with the results, can't remember what carb though (850?).
I think I've got just about all my pieces rounded up. My shortblock is together and my headgaskets just arrived. I'm planning on running a flexplate this time so I need to get one of those adapters for the driveshaft. That, an oil cooler and some plumbing and I'm set. Then it's all wrenchin' from there. ;)

[PANTHERJET]

well i might just break down and buy an 850 and give it a try malcom good luck with your olds

[centerhill condor]

charger and the others are correct.... too much carb from more than an 850 cfm... no charge.

[JLB440Stroked]

PantherJet,
I have a 440 stroked to a 500, with simular oiling problems, weight of rotating mass, etc. I feel your pain! I would suggest if building a blower engine, as for parts cost and part stock save yourself some trouble and go with the 454. I know it's the same as many, but the pros. out weigh the cons.
As for the carb. if your going to go to a blower setup on any engine you'll need a larger carb. but to larger will lean out an engine, NOT make it to rich. It can go to rich but not due to cfm.

I've got an 800, 850 and 950. If you are in PHX we can give them all a run. I can get my hands on an adapter plate and 1050 or 1150 too.
I too am looking to try a 950HP or 1050, just waiting for the pump to go back together.

I had the same problem with an Edelbrock. A double pumper fixed my problem. Dominator would be to big for your rpms. 950 HP Holley.
I just put a Victor intake on mine with a Demon 850. Love it. Runs much better than the tunnel ram with Edelbrocks.

[HotDogz]

at 5600 rpm, i would think that E heads would be your main limitation at that rpm (even ported). switch to ported edelbrock heads for more air. those damn iron heads can only breathe so much air. I hit a flat spot @ 5300 RPM on unported iron heads. just wont breathe anymore.

[PANTHERJET]

It Be Great To To Try The Others But I Am In Montana
