850 vs 1050

Post  BigRigTech on December 23rd 2013, 2:06 pm

Being winter and all I've been spending some time reading various race topic's and one that struck me as interesting was the whole 850 vs 1050 carb swap. Several times on different forums/ various brands I read that racers were making more HP on the engine dyno with the 1050 dominator but the car ran better times at the track with a good old' 4150 850DP. Has any one here been down this road? One common theme was that a lot of these car's were foot braker's. I like to see what the Mopar and bowtie guys are finding/trying on engine's close in CID to our BBF's....Can you tell I'm bored with winter yet? Rolling Eyes

When we first got my 460 running we had a 4500 flange victor intake with a 1050. Car went 11.42@122. Swapped to a 4150 flange victor and a 850 holley. Car went 11.80@116. This was with no other changes. Needless to say the 4500 intake and 1050 was put back on and car went back to where it was. Motor is a dove headed 466, small solid roller, 2443 pistons, stock rods, crank, c6 leaving off the foot brake. Car has went a best of 11.11 with Lennys converter. Im pretty sure its got a 10.90 in it but only got 1 good pass in with the new converter. Motor made 442hp/422tq at the tire. Car weighs 3390 with me in it. My vote is go with the 1050.

Has a lot to do w/Combo. imo if it likes a roller or big FT cam,it will like a 1050. BBF's seem to love fuel and lots of it. Smile

Good to know, real world experiences are always nice to hear. It's all dependant on the combo I guess. Wink

I need to try the swap on my 514. Problem is I need to run one of those adapters and not sure if that will negatively affect my results. Old 850 has been doing well for a long time

If I can get my hands on an adapter and a 1050 when it comes dyno time I'll try swapping from my 4150 victor/850 to the 4150 intake with a 4500 adaptor and a 1050. 1faststang will lend me his 1050 if it hasn't sold my by then, I'm hoping to scratch up the cash ASAP to just buy it myself.

I ran a pump gas 514 with old A429 heads for years...hundreds of passes, with an 1150 Dominator.  Car ran high 5.80's @ 2700 lbs., shifting @ 6200 and spinning 6600 in the traps. Everybody told me I had too much carb on an engine that size. So I borrowed a good running 1050 Dominator from a friend's BBC.  The car slowed 2 tenths.  I admit that I didn't try to tune the 1050 to try and recover some of the lost e.t., but....the 1150 went back on and stayed.  Haven't tried a 1250.

It's a pump gas motor maybe 650 or so hp. Been 11.25 117 on motor with a tight nitrous converter. Just cracked into the 9s on a 200 shot. 4000lbs full size truck.

I'm curious, how would a 4150 1050 cfm carb work compared to a 1050 Dominator

Typically the dominator will make more power

David, regarding your carb choice on 572 EMC build - was your carb flow tested after modifications to see what it actually flow's? How much HP would you think you left on the table by not being about to run a 1050 dominator? I spent quite a while reading about the EMC engines last night, pretty cool stuff there. Big cubes still the king but those little 32V's are killer. I had a stock 01 Cobra SVT before my drag car....That thing would scream to 7000rpm in 2nd gear at 70mph for a joke. Very Happy
