289 hp estimate
building my first 289.
the 351W i built in HS was an absolute beast!!
well, here's some specs on my 289 what do ya'll think i'll push hp wise?
1967 289 .040 over, stock pistons
block decked .010
heads decked .010
cam: 204* intake @ .50, 214* exhaust @ .50; 114* centerline; 441 472 lift
otherwise stock rebuild. thoughts?
thanks,
sean

all vaild points
carb will either be a 500cfm holley 2bbl or a 600cfm Carter AFB, i have both sitting in my garage. either one will be perched atop an edelbrock performer intake.
exhaust will be handled by the stock exhaust manifolds out 2.25" single exhaust.
i have no idea what the stock compression ratio is on a 289. so i have no basis to work with, however i would have to assume with only a cleanup of the head and block no effective increase in compression over stock. The 289 i have came out of a '68 Mustang, so maybe someone with more FORD knowledge could help me out with what the compression ratio really was to start with.
the heads are a stock rebuild with standard valves, no porting.
the 351W i built was actually in college and was a much more significant hop up project. so, i am not expecting as much from this one, but i was curious what sort of performance i could expect.
thanks,

1968 289 heads would have a cc of 63, but you would still need to cc them to know, also need gasket thickness and piston to deck numbers to get a compresson ratio.
Is that a performer cam?
I would guess 225-240 hp.....depending on actual compression ratio........I would go with the 4bbl carb, if it were me. Is this going in another mustang? Later

don't kill me but...
the 289 is destined for my '59 F100. the engine was free and i picked up a 3spd tranny out of a '67 mustang as well. its not gonna' be a REAL hot rod, just a daily driver.
yes, the cam is the same specs as the edelbrock performer.
i am using fel-pro gaskets, compressed thickness is supposed to be .040".
as for the piston to deck height, i won't know until i get it back from the machine shop. it will be assembled at the end of the month.
have you used the Carter on a 289? what jetting/metering rods seemed to work best for you?

I use a 600 cfm edelbrock (same thing as your carter) on a stock cammed 351w and I went all over the place with jets/metering rods and stock settings were fine. I would expect you would need to go smaller, if I am not mistaken someone made the comment edelbrock would recommend the jets and metering rods to a persons engine, so maybe you can give that a shot.
Do you have the cam already? That cam will do the trick but when I spoke with a few cam grinders on that specific cam they didn't seem to like it at all, they almost all recommended a comp cam, something like a XE250H part number 31-230-3 or XE256H part number 31-234-3, strong low end torque. Keep in mind I gave them a lot of grinds to think over, including all the paw grinds (which I will assume is the one you have or want) which just happens to all be old crane grinds, the performer included. Just thought I would mention that, something to think about I suppose.
Nice truck, I haven't seen too many 59 fords, what the six wasn't strong enough for ya?
Again looks like you have a nice project going on, let us know how it comes together, later

the 6 was ok but...
i drove the 223 for about 3mos, but i got tired of my fishing buddies asking if they needed to get out to help push the truck up the next hill! and i live in TX!!!! so, started talking to my bud about it, and about the same time he decided to put a hot rod 351W in his 'stang. well, the 289 is mine for the truck.
i chose the cam because it seems everywhere i read, fords need to have more lift and duration on the exhaust side, and that one fit the bill. i used a performer cam in my last 318 (i've built more mopars than i can recall)and it ran real well. additionally, that 351W i built back in college ran a performer rpm cam with a great deal of success.
anyway, cam is on the way, so i guess i will use it. the great thing about the '59 is, i'll have plenty of room if need be to pull the cam out in truck if i really hate it.
i hope to have the truck back on its feet the first weekend of so June so, i'll be back and will post pics on my gallery. thanks for the help.
