1966 Ford Mustang 289 HiPo

This is my 1966 Ford Mustang with a 289 cubic inch "K" code High Performance V-8. Still using the factory internal guts, but have full roller rockers, guideplates, race valves, 3 angle valve job, port/polish, all round port matching, 10:1 compression, pointless high energy ignition, etc. Has a Weiand Stealth high rise, 1" spacer, Holley 670cfm 4-barrel (huge for a 289). Custom cam patterned around a 289HiPo/Boss302. 230 duration @ 50, 270@20, 108 LSA, 500 lift. Very hot cam with a nice medium lope. (more)

WOW! Sounds and looks amazing! I'm having manual transmission jealousy though. Haha I have a 3 speed auto. I wish I knew what all that meant. The cams especially interest me. I have a '65 with a 302 two barrel (obviously not stock ;) )

And I'd like to do something to spice it up a bit. I don't really understand the cam except that it lifts higher for more fuel, which means more compression and more power Yes? No? Lol

@ParkTrotPlease Thanks. Higher lift simply means the valves open more. .500" vs .415", for instance. The other critical number to understand is duration, which refers to how many crankshaft degrees the valve is open at a given lift, typically .050". Simply put, longer duration gives the fuel/air mixture more time to enter the cylinder. Easy ways to spice up your 302 would be a new 4bbl intake, 4bbl carb, warmer cam, and headers.

hey im a mechanic and if its got 27 miles on it you should not be reving the engine like that you'll blow a head gasket or worse you could bend the push rods and then it would screw up the engine and then you would have to rebuild it so thats a bad idea just wait untell you get 500 miles on that engine before reving it like that k

[donlugohs]

@bree7878 I wish you had read in previous comments that I'm not interested in the least in comments from youtube users regarding any "suggestions" about my car. Although I'm sure you mean well, most of you are morons who are clueless about cars, and as I previously stated, I'm confident I know what's better for my car than most of you do. Unfortunately, your comments only reaffirm my beliefs that you do not know what you're talking about.

[donlugohs]

@bree7878 For instance, the head gaskets and pushrods aren't affected at all by the break-in process. The head gaskets are fully set once the stainless steel compression rings have been crushed. The pushrods are factory heat-treated and do not experience anything closely resembling strength increases during break-in. If you'd been concerned about bearing or ring seating, you may have been more believable. Also if you were a mechanic, you should know revving a fresh engine to 3500rpm is harmless.

I'd bet that you love adjusting those solid lifters eh? Haha, nice car

[donlugohs]

@NWpowerhouse85 It's not too bad and doesn't have to be done all that often. The engine is out of the car right now and I'm currently reassembling it. Changes will include increased compression from decking the block and milling the heads some more. Also decided to go with a hydraulic roller cam for now, a Comp 31-601-8 Mutha Thumpr . Have a new exhaust built for it as well, 2.25" mandrel bent with a custom X-pipe and Flowmaster 50s.

@punnkypo the k codes usually had close to 305. but with his set up maybe a little more

[tbmike23]

Man I know that sound so well. I miss my '64 1/2 more than I miss my old dog.

[FlamingTightyWhiteis]

thats a VERY nice car,i prefer the inline six personally.love the valve covers

[kingkoax]

Nice! i got a 66 mustang, i don't have the 289 in it, still have it, but i got a 351 in it now.

i know i will hear "there is no such thing as a 351"

[punnkypo]

so how many horses are you pushing in that stang for a 289??

[skytrooper30]

I just bought a 66 mustang 289 and I cant make up my mind as far as what kind of shorty headers I should add, especially what type of dual exhaust. Can someone please help.......thank you

[kd5icr1967]

Thats cool that you get power out of a little 289. That should shut people up that say you cant do much with a small displacment engine. Well done. 1 thing, why solid lift?

[kevykev38]

I have a 289 in my 1950 Ford. This engine had fuel injection . I recently changed it to points and carb. I have been told the engine will never run right doing this. That i would have to change it back to module electronic ignition
