What's a 289 hi-po worth

I've got a 289 hi-po block, heads(assembled) and crank. It all has surface rust but appears to be good otherwise. Have a guy interested in it but would like to know what it's worth.

 

I gave 250 for my complete 1968 289 engine + 3 speed. Nice running motor

 

Worth more to the Shelby guys...289 Hi-Po is a must for 65, 66, 67 GT 350's. i might ask this same question on the shelby forum or one of the other Shelby sites.

 

It depends on numbers and items like the harmonic balancer , rods , distributor , fan blade , carb , exhaust manifolds $2500 - $5500 . A friend of mine just sold an early 5 bolt short block for $2500 . Even the motor mounts were unique in 65, and they can bring 600 - 1000 bucks

 

First what year is it and does it have a number stamped in the right side of the block just above the oil pan rail at the front ?? >>>>.

 

Exactly, year and numbers will determine if it is a real k code engine and its actual value. Even if there is no vin # stamped in the lower right front of the block it can still be the real deal, but that would definately help verify it. If it has C8ZE / C8ZZ service casting numbers , the value drops quite a bit. You can always go to www.hipomustang.com for more info.

 

It will have considerably thicker maincaps, stick out like a sore thumb with the oilpan off for inspection, only other smallblock with thick maincaps like the hipo 289 were the mexican cast 302 blocks, easy to identify, they have big casting knot on them on the front of the block just below each cylinder heads, and say hecho en mexico in lifter valley, if you have a real hipo it's worth some coin to the right person.

 

GT 350's where 306 HP not 271HP.Thse motors are VERY Rare.
Ever notice how many GT350's there are out there? About 20,000 more then they made!!lol.

Stupid me pulled the original one out of my fastback years ago because it had around 120k miles on it and replaced with a stock low mileage 302....The hi mileage hi-po ran better but i had already thrown it away.....

 

K-Code = 271 HP (Shelby 306hp)
A - Code = 225 HP
C - Code = 195 HP

Depends which motor it is. A K-code motor should have the VIN stamped on it.

 

Quite a bit difference between a standard 289 and a Hipo:
The HiPo engine was engineered to increase performance and high-RPM reliability over standard 289 fare. It had solid lifters with hotter cam timing; 10.5:1 compression; a dual point, centrifugal advance distributor; smaller combustion chamber heads with cast spring cups and screw-in studs; low restriction exhaust manifolds; and a bigger, manual choke 595 CFM carburetor (std 289 4v was 480 CFM). The water pump, fuel pump, and alternator/generator pulley were altered; fewer vanes, extra spring, and larger diameter respectively; to help handle the higher RPMs. Even the HiPo’s fan was unique. Bottom end improvements included thicker main bearing caps and balancer, larger diameter rod bolts, and a hardness tested and counterweighted crankshaft, all for high-rpm reliability. The HiPo carried SAE gross ratings of 271 hp (202 kW) @ 6000 rpm and 312 lb·ft (423 N·m) @ 3400 rpm.
The HiPo engine was used in modified form by Carrol Shelby for the 1965-1967 Shelby GT350, raising rated power to 306 hp (228 kW) @ 6000 rpm through use of special exhaust headers, an aluminum intake manifold, and a larger carburetor. The Shelby engine also had a larger oil pan with baffles to reduce oil starvation in hard cornering. Shelby also replaced the internal front press-in oil gallery plugs with a screw-in type plug to reduce chances of failure.
From 1966 to 1968, Shelby offered an optional Paxton Supercharger for the 289, raising its power (on Shelby GT350s) to around 306 hp (228 kW).
The K-code HiPo engine was an expensive option and its popularity was greatly diminished after the 390 and 428 big-block engines became available in the Mustang and Fairlane lines, which offered similar power (at the expense of greater weight) for far less cost
Out of smallblock ford identifying book.
Alot of identifying factors, definitely make sure thats what you got, if it has everything listed it's worth alot for sure!

 

271 HP 289 Hi Pos are worth alot! I just sold some K Code Heads last year for $1400

 

Casting# on the block C5AE-6015E 5L1..... Don't think the heads I have are hipo, no screw in studs.

 

Thick main caps ??? >>>>.

 

They were bringing an easy 1500 4 years ago. Big caps and high nickle content. Mexican blocks bring close to the same.

 

Check the main caps if it has the thicker ones like in this pic you know for sure:


Main caps have the beveled edges it's a standard 289.

 

There are no main caps on the block. The heads I have are not hipo just a run of the mill 289 heads, have approx 54cc chambers, 1.78/1.45 valves.
Date codes on the heads are 5G14, 1965 July 14. And 5L2, 1965 Dec 14.

 

Starting with 1965 production, the C5AE-6015-E blocks were cast by Ford's Cleveland Foundry for use in building ALL versions of the 289, including the HiPo's. Many specific parts must be used within the basic block to make the HiPo, and it can't be identified by just the casting number on the block. This is the casting# that I have.

 

As I have said before ""289 Hi-Po"" Aren't They All HI-POs and how in the hell did this thread even get started ?? >>>>.

 

not to be an ass, but it sounds like we are heading closer to a $125.00 a ton
