After trying out Mike's(Mr. P-Body)1050 dommy on my .040 over 440 last sunday at the strip,I was wondering where you guys jetted, running a modified 440,and 1050 carb? It is currently jetted at 88 square. Mike had installed 84's,thinking the 88's would be too rich! After checking the plugs,the jetting was too lean,in my opinion! Also...MPH dropped by 2-4 from the 850 holley! Any input would be appreciated! RandyB

On my old 65 with the 11.1.1 440 at the time. with a box stock 8896 Holley 1050. If i remember right Dewayne had me set it up with 92 jets with pv in the front and no pv with 98 jets in the back.I ran 10.56 @ 125 set up that way.that carb does look awesome on your car. Bobby

Start it out at 88s Randy but have jets to jet up
88s were in it standard... we're going out Saturday
if you want to come... opens at noon

Thanks Bobby! Mike,I put the 88's back in earlier this evening,but haven't changed the slicks back to the street tires as of yet! I don't dare drive that car on Belle River Rd. with slicks,I'll end up in a ditch,or one of the many corn fields around here! As far as saturday goes,sounds like a lot of yard work to catch up on,according to the "BOSS"! She's usually right,even though I hate to admit it! Let me(US)know how everything goes with you and Doug at the track! Best of Luck!

90-92s on my 440 with a 1050

and 38* timing too

Thanks,Ari! How modified is your 440? Any idea how much hp and tq it makes?

Labratt, What fuel are you using in your car? I usually run 92's square jetted in my 8896 dominator on my 408 smallblock. However, i'm running pump gas, which i use more of than race gas, because of the lower octane rating.

446 ci
12.5 comp
613/276 u/d cam
stage 4 ported heads
M1 adapter 1050


10.85 123 mph

car weigths 3470 with me in it




I have a 511 indy sr,m/w motor in my car now

Andy,I run 100% premium unleaded from the pump. Stock Eddy Performers,only 10:25:1 compression! Timing's set at 39* total.

Is this carb. a stock Holley? If so what is the list number on it and the dash number if it is a HP Domininator? I have found that starting with the stock jetting and going from there is best when you don't know which way to go on a second hand or borrowed carb. If it is a custom carb. start testing and jet up until it slows downs

Cab,I'll have to get the numbers off of it tomorrow. As far as I know it's a factory,un-modified non-HP model. It belongs to Mr. P-Body! While we're on the carb subject, have you guys ever seen anyone run square jetting,with a PV in the primary???

I just looked at the first pic in this post...If that's the carb it is a 'new' model Dominator. As has been said I'd reference the designed/engineered fuel metering and move from there.

Thanks Sean! That's all I know is Mike said it came with 88 jets,out of the box. So...I'll start from there next time out to the track,probably in 2 weeks. Almost certain the Gratiot Cruise is next Saturday! QUESTION!...ended up with 82squared on the jetting with a pri. PV,on the 850 when it was on Jake's dyno a few weeks ago. Has anyone ever seen or heard of squared jetting with a PV??? Engine responds well,makes good power,but I've NEVER seen squared jetting using a power valve! BTW... A/F ratio was 13:2 with this combo. When I brought it in,I had the jetting set at 82/90 with a 4.5" pri. PV,and the A/F was 12:9. Temps were 83-85* and humidity was 41-43%! What do you guys think? RandyB

I ran 88's front and 92's rear, no power valve in bad air here in Las Vegas. I had a 446 11:1 and the 8896 carb.

Just got the # off the dominator. It's a 8896 w/4-corner idle! BTW...what # dominator is generally considered to be the best for street/strip??? THANKS!

Sounds like you might need to work on hooking that puppy up,,,was blowing the tires off big time once you nailed it.
Clamp the front section of the leaf springs ?? hmmmm



PS,,,i found another labrat guy,,,and put some "thoughts" with him,,,lol

Thanks for another LabRat,at least it's not a LabBat,like the last one!! Good news! Just got a good deal on some brand new Goodyear bias-ply 29"x9" D-3 slicks! Should be getting them early next week. Brian Harlow got me a good price on the tires,and the shipping! Should make a difference coming off the line! Doug is right,when I hit it off the line with the Dominator on,it just blew the tires off! Spun for the first 40-60 ft.! BIG increase in low-end torque,and under lean conditions!

Still waiting for an answer on my square-jetted using a power valve question! ANYONE EVER SEE OR HEAR OF THIS BEING DONE??? Thanks! RandyB
