Ford 289 Hypo vs. 302 Hypo
I have a '67 Mustang Fastback I'm slowly but surely rebuilding to make it a GT350 clone. I found a '67 289 out of a Fairlane or a Galaxy 500 (I have a toploader 4-speed too, the engine came out of one the above mentioned cars and the tranny came out of the other - can't remember which).
Anyway, I've located a 302 Hypo with the original aluminum intake and the original aluminum valve covers. I believe the 302 Hypo will have more HP without spending as much money...??? My question is this: Which engine would be best to rebuild for my application? All feedback is appreciated. Thanks, Dave

I'll ask the resident Mustang expert today at work - he used to rebuild them for before going "Hollywood." I have a feeling he'll say the 302, but we'll see.

Dave,
Are you trying to make it a period correct GT350 clone? If so, I am pretty sure they came with a K - code 289. I am sure the 289 you got out of the Fairlane or Galaxy is a garden variety 289, which from the factory made 225 HP, I think. A K-code 289 put out 271 HP. If you are just looking at making it a fun driver, and not trying to win any show points, etc. (which I doubt you are, if you are turning it into a clone) I would go with the 302 as it sounds like you already have some of the parts needed to retain its Hi-po staus after the rebuild. It sounds like with the 289, you will need to buy some of the parts to make it a K-code. This probably isn't the best place to be asking, I woudl try one of the zillion Mustang related forums. A google search would most likely point you to a ton of them. I woudl give you some links, but unfortunatly all of the Mustang forums I am on are 6-cylinder related. Now if you wanted to know how to get 200 HP out of 200 ci straight 6, I could help you with that, smile. As mine has a progressive linkage with 3 webers, and all kinds of all fancy bits, smile. Hope this helped, Bill |

Yes sir and I thank you!
 I've found there are so many people on this forum with a vast variety of knowledge, such as yourself, who often offer good advice on most any subject. It's the only forum I visit!

According to our building's Mustang expert, there is no 302 hypo motor. There's the 302 Boss and the 351 Windsor and Cleveland, but the 351 Windsor is more or less a bored and stroked variant of the 302. The Cleveland is a different animal altogether, built for road racing and evidentally very expensive.
BTW: here's a hilarious Mustang link from 1969stang.com: http://www.1969stang.com/video/69stang.wmv

The 351 Cleveland was the motor that was in the Panateras, and Boss 351's.....The 351 Clevelands are really no more expensive to rebuild than the others...maybe finding on is getting tough...

A true 289 Hipo will have thicker main caps and better rods among other things. 289 Hipo heads have screw in rocker studs and slightly better ports. All other 289-302s of the era had press-in rocker studs.
Agreed - there is no 302 Hipo. A Boss 302 is a totally different animal. If your 302 is from the mid/late 70s or early 80s don't bother with it. You're better off building from a '85-95 roller-cam 302 - affordable to do these days. Roller-cam 302s can pump out more power easier and smoother than any old 289-302 ever could (needs high comp and big carbs). I have a '66 289 in my '66 Fastback - built up to about 300HP 12 years ago. Next engine I build for it will be a roller-cam 302 stroker variant - can easily get 375-425HP reliably with parts available today. For Mustang use, make sure your Toploader has a end-of-tailshaft-housing shifter mount. Galaxies (I think) had middle-of-tailshaft-housing shifter mounts and that won't fit the Mustang. Conversion parts are available though. Unless you're dying for the Toploader, consider the T5/Tremec conversion - lighter, plenty strong, and much more fun to drive long distances. I put a T5 in my '66 (replaced the Toploader after 8 years) and love it. Visually and dimensionally the 289 and 302s will look the same (incl the roller-cam 302s). No substitue for cubic inches as they say. Easy to make a later 302/stroker look 60s vintage with parts available today too.

Pick up a 5.0 or Muscle Mustangs. There are more parts available for these engines than any other. You can get a 347 rotating assy. from Scat for around $1k, add a set TFS or Edlebrock heads & intake, Cam Motion or Comp Cams cam & you'll have a reliable 450+. In Street Outlaw trim these motors make 2000 hp.

How does one convert it to a GT350 clone? Is it addition of scoops? Were there body changes? Always wondered what the difference was. Is it just engine and body, or was there suspension mods?

The picture I posted of my Black 69 Mach1....is a 428SCJ, with extensive Suspension, Brake and Engine modifications....even the power steering box was blueprinted....so there ain't no Ford steering slop....

You had to extensivily modify American cars of the era to get what you got from Porsche stock!

For a 67 GT350 Clone...I would either go with one of the later engines as specified earlier in this thread....find a Boss 302 engine or a Solid Lifter 289 with a Paxton Supercharger to be stock....
Check out Global West Suspension systems to make it handle, Put in a Lincoln Versaille rear axle assembly...for rear disc brakes, you need to have a pair of 31 spline axles made....all mated to a nine inch Detroit Locker.....Bill Thomas in San Bernardino is the man....to talk to... actually 31 spline axles would be overkill for a small block.... Do your body parts to give it the look....

I've had hankerings now and then to build a late-60s Pony car road racer. Mustang, Camaro, Pontiac, Challenger. They're all cool cars in my view.
