289 Ho

I recenlty bought a 289 HO motor complete and aseperate 82 Bronco to put the engine in. Pulled the 289 apart, found out it's got 302 heads and now it has an 84 Mustang 4 bbl ford intake along with a brand new edelbrock 650.put new gaskets double roller timing chain hi-flow oil pump and tune up in it.....it has great spark, great fuel and good air.Still won't fire.Timing chain is dead on....still tinkering with the fulcrum head valve adjustments.New blue streak cap/rotor.Autolite platinum plugs and 8mm wires.80 gph Holley mechanical FP.Still no fire....it does pop when it tries....have tried both the 302 and 351w firing orders....still no luck....pretty sure it's the 302 since I'm looking at the rockers as it's cranking over(valvecovers are off for adjustment) brand new accel coil...as well as an ignition module...like I said great spark and good fuel/air.....any ideas?been too weeks and getting frustrated with it......did I mention how much I hate timing?????

The only Ford 289 HiPo engine ever offered (271 HP with SOLID LIFTERS) was optional on 1965/67 Mustangs (the so called K cars, because the letter K was used in the VIN) and standard on 1965-67 Shelby GT 350's. The 302 engine was first offered in the spring of 1968. Ford never made a 289 HiPo with 302 parts. After the 302 was introduced, Ford stopped using the 289. The 289 was never offered in F Series trucks, or Econolines.

289 1965/67 Passenger Car VIN Engine Codes (5th digit in VIN)

A - 289 4V

C = 289 2V

K = 289 HiPo

I know this....it IS a K code engine out of a 67 Mustang coupe.....it also has a reman tag glued to the blockalong with several ZZ stamps in various places as well as the .060 stamped into each piston...I did my homework teacher, but you didn't answer the question(dang public schools)In the process of the reman not only did they pull the 3/8 connecting rods but swapped in the standard 289 rods (5/16) but also, as I found out from the wrong spark plugs, it has 302 heads, which surprisingly have smaller spark plug ports......

if it pops thru the carb either the timing is wrong
or the valves are not closing
check for compression readings to verify the valve adjustment

Thank you MHG now that is a response I can respect.I was thinking about the valve thing and compression...but what should it be?or should I just go from cylinder to cylnder to find variances?

You can check compression for consistency from cylinder to cylinder. This will tell you if the timing chain is correct, since the valves won't be closing at the right time if it's way off.

If you turn the engine by hand to TDC, then both valves on #1 cylinder on the passenger side front should be closed. Turn the engine 1/4 turn, and then look to see what cylinder has it's valves shut, compared to the 302 or 351w firing order. You should be able to keep turning the engine 1/4 turn, and follow the correct firing order to determine what camshaft you have in the engine(if it's a 302 cam or a 302HO or 351w cam.

I didn't answer the question, simply because I wanted to explain what the 289 HiPo was and when/where it was used. I have a bit of knowledge in this area since I worked for Ford 3 yrs before the engine was introduced, and used to own the 5th Shelby GT 350 made. Most ppl weren't born when this engine came out, so that's what I posted what I did.

Ok, maybe I'm playing devils advocate here a bit, but why don't you sell the motor to a mustang guy if it's a real K code, and have enough to build a 302 or 351 with more power and money to spare?

Deck height, rods, head bolt size, cam timing all change/increase for the 351.

Stroking the 289/302 was not done until fairly recently when high flow aluminum heads became common place.

the only thing left on the engine of value to collector/restorers will be the block and if youre lucky the crank.....and since the block is punched out 0.060" its on its last life.

Available in Shelby GT 350's, 1965 Falcons, Comets and 1964/67 Fairlanes in addition to Mustangs, but only the Mustangs have mostly survived. There was little or no collector interest in Fairlanes till only recently. Most of the cars except Mustangs and Shelby's that originally had the K engines, have had the engines removed, and installed elsewhere. The engines are desireable today, because there are more K cars around, than engines. The K engine code in the VIN adds $10,000.00 + to the price of a 65/67 Mustang, if the engine is correct.

If it is backfiring it sounds like the timing is wrong. Firing order should be 15426378 if it is a 302 or 289 cam. If you have the valve covers off wind the motor over until number 1 cylinder valves are rocking , keep turning engine by hand , number 5 cylinder should rock next . Continue until you are sure what the firing order is . Check that you have the spark plug leads in the dissy in the right order and right direction .

if ya take a step back and remember the kiss (keep it simple stupid) method only 3 things are needed to make an engine run, fuel,spark,compretion so if ya have all of those and every thing happens at the rite TIME it'll run.
