7500 RPM 289

    Hi again HIPO 289 Friends.


    Although not in a Mustang chasis, I though you all might enjoy seeing one of my 7500 RPM 289 screamers running a against a Buick Turbo. Amazing what these 42 year old motors can still do!

    I'll second that..... sounds sweet!


    What are you using for an automatic trans? Are you shifting manually at 7500rpms? What kind of build on the 289? Estimated HP? What does your TR-4 weigh in at? ET? MPH at line? RPM's at line? What rear end are you using?


    Tom

    Thanks Guys!


    What are you using for an automatic trans? - (C4)


    Are you shifting manually at 7500rpms - yes?


    What kind of build on the 289? - Pretty much super-stock build with big Lunati Mech Roller Cam. Crower 289 Rods (no stroker) a must!!! as well as dynamic balance job! Pretty much Stock C5 small chamber 289 heads with mega K-Motion Springs. TRWs kept hitting valves so I went to .030 Wiseco Forged pistons.


    Estimated HP? - Although it sounds like a 480HP vintage race motor, I believe I am making just over 306HP ((306HP/2230lb w/driver)^.318) x 225 = theoretical 1/4 mile MPH = just under 115. Although I have run low elevens with the 8" converter, I left at an idle here with the 10" converter and ran 12:00 at just over 114 MPH Deep Staged!!!


    1957 Wagon 9" Rear, 4:86 Cougar "N" Center w/Detroit Locker (Factory Posi seemed to slip after a while) 28" BFG Street Drag Radial.


    Thanks again for the interest, John

    That is a very specific build. tell us about the valve springs, the valves, and their sizes, the cam lift and duration. Many of our readers don't realize the gains associated with getting the engine to breathe. the heads have to be right, [ HIPO!} and then moving the gasses.what is the carb? hipo or other? Very sweet, thanks for sending the evidence of the real thing in motion!!<img src=images/icon_smile_big.gif border=0 align=middle><img src=images/icon_smile_big.gif border=0 align=middle>

    Valves - just about stock (small size). Used new (Farias I think) due to extreme seat pressure of mechanical roller cam.


    Valve springs - K-Motion for Mechanical Roller Cam.


    Cam is a brand new 1986 Lunati grind. I met this gentleman at ATCO over 20 years ago and was amazed at his running a full weight metal Ford Falcon in the high 10 second bracket with stock 302 Windsor heads! He was nice enough to have Lunati share this grind with me (thru ATI in Md.) and it stayed new in the box until 2005 when I rebuilt the motor.


    Cam Lift - .660" w/Harland Sharp 1.6 rocker arms.

    Duration - 268 Deg. @.050" intake and 273 Deg. @ .050" exhaust (I believe.) I have been thinking about trying the new Lunati VooDoo series cam and am sure the folks at the factory would have even newer grinds too for any of our interested members.


    This is an odd engine by today’s standards as the cubic inches are tiny at 289 x 1.030 and the heads are tiny high compression units dimensionally very close to un-ported stock HIPO 289 castings. The Carb is a Holley 650 CFM but I ran an Autolite 600 CFM 4100 on this motor for years and recently put the same Carb on the Dyno with my marine 289 and made essentially the same HP as the Holley (2-3 HP more with the Autolite that had 68/72 jets vs. the lean Holley 67/71 street jets that are in the car in the video.)


    When I was a kid, I used to read Superstock Magazine; there was an article on a "K" 2+2 Mustang called "High Winders" that stuck with me until I could build this motor many years later. In NHRA Superstock in those days, if not now, you could optimize the clearances ("blueprint" the motor) but the heads pretty much had to be stock. So in summary the breathing improvements seemed to come from the cam!

    THE obvious breathing enhancement, if you can't touch the heads. There have been many gains in the camshaft and valvetrain world. There is roller this and roller that, and the weights are down to nothing, so we are left with the core HiPo prizes of the heads, the block/caps, the balancer, water pump, pulley, dual point, autolite 4100,....what have I missed? This engine is the focal point for us of this site. A gem for all time. <img src=images/icon_smile_big.gif border=0 align=middle>

    Great story, especially the ATCO part. No matter how the engine is built, you gotta love it when an American V-8 is dropped into a vintage British sports car, especially when it's a Ford 289! <img src=images/icon_smile_tongue.gif border=0 align=middle>

    I bought the car with a 302 automatic 2 barrel half done. Work by previous racer, fabricator, owner was extensive fabrication; firewall, motor mounts, trans mount and tunnel, steering etc. I since added Sunbeam Tiger headers (had to be modified by a chassis welder), nine inch rear (I did driveshft and spring perches), cage by a professional chassis builder.


    However, there are a couple of real good web sites for British V8 conversions (google these words)that can get probably get you going in the right direction. Also the kit car show at Carlisle PA.


    Best, John
