Mean 77 on Ebay ??

Someone in WI selling a 77 on Ebay (160273923832)Has anyone seen it pull? Sounds like a lot of HP out of 300ci.
 
I'd be pretty leary of buying something like that, who knows what you're getting? One thing about it though, it doesn't have "290HP". Hell its probably doing good to have 120HP
 
We have a lot of tractors here in Wisconsin that are way over 20% factory hp! I have not seen the 77 pull ever, but I have no doubts that it is as big as he says it is. A lot of Olivers, Farmalls, John Deeres, and even a couple Masseys are over 20% hp here.
 
It's legit. 12 port head, headers, and Stromberg 7 carb set up. 7 main block; 292 cube; water in block and head yet. Ported head. 6000RPM from what I hear.
 
Did he beat you. I'm not saying it isn't true, but it doesn't sound right to me. Maybe the rpms could get him there, I don't know. I doubt it though
 
I'd bet that he's talking about a 283 chevy engine. Remember those? Gosh, I loved the one that I had in my little shortbed chevy truck! Economical as heck, but good power too. Those could push some ponies if someone knows how to tinker with 'em!
 
20% over factory isnt that hard to get.I once pulled a Wards tractor that dynoed 120 horses from a 265 cube plus .125 over flathead Chrysler 6 turning 2000 rpms.It was 10-1 comp,mild cam,dual carbs,and dual exhaust.This was nearly 300% over factory.We turned it 6 grand when pulling.The AC dealer wanted to dyno it because were were beating a customers turboed WD-45 diesel.

If this 77 Oliver is set up for an open rpm class it could well be over 150 horses but I doubt that its got what he says it does.1 hp per cube would be hard to get with no turbo.
 
The 77 is what it is, I've watched it for a few seasons. It's just that simple it's tough to beat it's a 21 mph tractor with a strong running power plant. If you can't get better then 1 hp per cube you need a different engine builder. One of you should buy that oliver and party down with your buddies.
 
Over 1hp per cube boy guess i better get working on my 226 cube allis motor My opinion is most all these old enfines would explode trying to get that and if thats the case then everyone is waisting there time boring and stroking
 
12 port on a 77? Might make a good brush puller but would not fit into any of our rules.290 out of a 77...hmmmm I wonder how he would stack up at 10000 against the 1066s around here that are pulling with a measley 250 hp.
 
Tell me which engine builder is making 1 hp per cubic inch and I will go to him on my next motor. Its not happening with any builder. At least not in an antique with no turbo. If it is I can't wait to get my 1100 cubic inch motor back from my builder.
 
I"ve seen it pull, as well as pulled against it from time to time also. Bear in mind that that number is coming from an engine dyno, its not like its putting all that power through the rear tires. While I don"t personally accept a number quite that high, on an engine dyno with the motor screaming at about 6k, it is possible I guess. Also, yes, it is set up as mostly a "brush puller" in that its set up with headers, massive carb, etc and no rpm limits at all.

With all that in mind, also remember that you can go out and buy a 200hp outboard motor for your boat, and it will have far less cubes than the 77 does--but nothing to speak of for torque either. It does pull competitively with tractors that I would estimate as having around 125-140hp with some torque. I am not trying to cause any bickering, it is a nice pulling 77 that does quite well, and pulls real evenly with a couple of built AC WCs in the 3600lb class, but at the same time, it doesn"t fare too well when matched up with 88s and Farmall Ms, etc, that are running similar setups. In the classes that he pulls in around these parts there aren't too many rules and the name of the game is wheel speed and RPMs, with not nearly as much emphasis on torque. With the exception of one big cubed minnie-mo that just doesn't die (and still turning some decent rpms anyways) most guys are building "screamer" type of motors for this class, rather than doing extensive motor work in terms of massive cubic inches, and a big cause of that is the way the sled we most often hook on is set up. The sled guy usually sets the sled like the NTPA in that it starts off of the line easy, with not much weight in the box, and lets the pan drop to stop you rather than more weight and gradual weight transfer, so around here wheel speed is absolutely paramount and everything else is secondary.

I will say that I'd be very interested to see the guys from these classes pull against the massive cubed NATPA div. 5 pullers and compare and see which method pulls better.
 
Well come on up then sunshine!! You guys dont have a damn clue what kind of pulling goes on up here in WI! Bring your big cube antiques on up some weekend and find out for yourselves! If you can't hit close to 20 mph or better ground speed mark in the hobby stock class you dont have much chance of placing.
 
I doubt hes getting 290 hp out of a 77, probably a hard time getting a third of that. I know a guy here that has a 88 Oliver that dynoed 120 one time and hes running pretty hot.

Any pull that has a speed limit for classes is a brush pull in my opinion.
 
While true, we know how to pull here in NW WI, you"ve gotta remember that some of those big cube antiques are hitting the same speeds in classes where max rpm is only 30 percent over stock (and they get tached after each run, its not like they're playing with the throttle stop). I"d be willing to bet a large sum of money that something like McQuoid"s Ollie 88, Bear's little Ford, and similar tractors would fare awfully well against the guys in hobby around here. There are guys pulling those "big cube antiques" down south getting gears made because road gear isn"t fast enough--I"ve yet to hear of any of our hobby guys looking for taller gears because they completely spin loose in all of the gears they"ve got.
 
I never stated once that you guys up in Wisconsin didn't know how to pull. I'm sure it is a great tractor and pulls well. I'm from Illinois and I know for a fact that there are some tractors here that could come up there and compete very well. I will bet a weeks pay check that the 77 in question does not have 290 hp. Thats all I'm saying. I have a tractor that would compete there at 30% over rpms and will come close, if not touch 20 mph
 
as much as i like allis 226 engines the head design is its limiting factor . the oliver with the cross flow head is in my opinion a better head than the 292 chevy head unless you weld two 350 heads together to put on the 292. down here is a 77 setup with 400 cubes that pulls 15 mile an hour 5000lbs verry competive seen it get past some 4 and 560s.
 
where is down here at?? i thinkyour are talking about east tn?? well I'VE NOT SEEN that 77 your talking about. you have better drop the mph a little bit for the one your talking about.

RANDY UNDERWOOD OWNS IT NOW TRACY REDD HAD IT IN MIDDLE TN BEFORE THAT . I WAS JUST GOING BY WHAT JACK TOLD HIM IT WAS RUNNING HE OPERATES THE SLED. :)
 
you guys are missing it...the 77 is set up like a car engine and being dynoed in a "car" way (engine dyno)...that inline six could EASILY have that much power...i had a 355 that put out 523hp on an engine dyno..don't tell me it ain't possible.
 
One horsepower per cubic inch isn"t that big a deal if you can run open RPM"s and pick the correct engine (enough flow and strength) to start with. Back in the 60"s just about any high performance engine worth it"s salt was rated at just under or over one horsepower per cube in the muscle cars of the era in a factory street able configuration. Race engines (naturally aspirated) did substantially better.

Move forward to the 21 century and you find 350 cube NASCAR engines making over 2 horsepower per cubic inch using a single limited CFM carb in the 8000 to 9000 rpm range.

Now I am not saying this tractor is or isn"t making the horsepower number being thrown around, but I wouldn"t be in a hurry to bet my paycheck against it without a lot more to go on...

:roll: youre right on target a 292 chevy engine can make 300 hp easy and was a agriculture use engine . 292 s are capable of 500 to 1000 hp if turbo but i still think the cross flow head would outflow a stock 292 head and i know the 1850 block will go alot bigger in the cubic inch department
 
That horse power is totaly possible. Ya he is using the 283 7 main out of a 1650 310 blocks are basically the same block. Bore, stroke, right cam, tunded headers, right carb set up, and ported head properly. That tractor has not beat me this year. Iv got one with over 300hp
 
Just so you know I dont take advice from morons telling me what kind of questions I can or can not ask. Dont waste your time Dumba$$
 
dick Adelsberger is getting 1 hp per cube on Olivers, got proof and dyno sheet( with out magic number added, straight up no BS) also ya'll keep in mind that at 5,252 rpms torque and horse are equal, so hmmm, an engine mostly stops making torque at some point and just wraps up a bunch of rpm, and what does RPM equal? Horsepower! the thing probably doesnt hang in there at the end but it sure will get there fast.MOMENTUM!!!! can beat torque not always but can. Also these huge cubic tractors, are some running the gear vendoe over/under drive for wheel speed at rated rpms? just food for thought
 
LDW, I'm with ya, everyone is missing the p[oint that the number came from a engine dyno and at 5252RPM torque equals horse, we run about the same rules here in Southern Ohio. Speed is the game, I will say this though, most of these 7 main 88 here are 427 cid and still cranking 5000ish
