Hey guys
Gentlemens I'm new to your website though I have searched your forum b4. Amongst my vehicles I own an 82 F-100 flareside. I rebuilt a 289 and although it was a screaming son of a bisquit I broke a ring during installation(knew something was wrong-high rpm runs blew oil all over my engine bay). So I pull the motor and after another rebuild I installed a set of 70 351w heads,a Torker intake and went from a 260 Crane cam to a 280. At the moment I am highly disappointed with performance. As I said my previous setup hit 6500 rpms so quick it was hard to shift fast enough,and when it hit shoot man that mother had no problem getting squirrely.
So I install everything as it came off the other engine (carb and timing) and it wouldn't get past 4000 rpms. After playing around I changed my jets(750 holley) from 68's front and 66's rear to eventually 76's front and rear and I am at 52-5300 rpms now.
I know there is another 1500-2000 rpm in there. I am reluctant to use bigger jets my burn is looking real good and adjusting my timing doesn't seem to do much at all. Any body with any experience on this swap please feel freee to reply. As far as saying my 289 is too small and all the big valve talk and all,spare me. I close to pulling the top end off and going back to the original setup- 68 302 heads and performer intake.

Well seeing how this is the first time seeing this post, welcome to the forums. I keep my trucks stock for nostalgia sake but a ring breakage doesn't sound like a walk in the park. I split my harmonic balancer when I first bought mine so I can't complain(drove it home that way too, ever try driving without the useage of your water pump and power steering? not fun).

Gotta wait a litte while dude, traffic picks up in the evening when more people get off work/out of school etc.. You might try posting in the engine specific forum as well. Since your engine was used in more than just this style of truck, you are more likely to get a suitable response. I wouldn't give you crap about a 289 in an F-100, hell it's better than the red headed stepchild 255 ford used in the early 80's.

I wasn't being impatient ya'll I figured I used the wrong icon. Anyhow I took a compression test and I only have 150# my other heads gave me 175# so most likely I'll swap out the heads and keep the torker on. A deck job on the 351w heads and I'll give them another shot.
Kudos to those who still have a job. I forgot what thats like hahaha

well maybe I'm expecting too much from this thing but when I run the calculator my compression ratio is up @ 10:1 that should be fine I would think but then my last set-up brought it in at 11.3-11.5:1

You sir, have reminded me of at least a half dozen 289's I have had the pleasure to have owned, I loved that engine. I made them scream. I'd forgotten.
Ya'll brought back fond memories, thank you

yes sir them little scutters will crank out some rpms. I never cared for the 302 and they never moved my truck like the 289 does. But then the 429 I got sitting off to the side might move that truck just as good

a 289 or 302 you wouldnt be able to tell the difference if they were built the same there so close.
check your ports also I built a 289 with the winsor heads and there are some ports that dont match up so you could be losing some vacuum.
aslo check your gaskets there are special ones if i remember right for this set up.
a 750 with those jets might be too much for the cam and compression your running .
check your throttle linkage also it might not be letting you get to WOT.
Just my 2 cents

if those are 68 302 4V heads, they are amongst the best heads ever put on a small block by ford. Not that the 351's are not. Compression plays a major part in torque, but there is no reason a 280 cam can't go 6000. Did you degree the cam when you put it in? Its my understanding that most cam manufactures cams are retarded from the factory, what i mean is that if put in "straight up" it will actually be retarded 4*. Best of luck, sounds like a neat project.

No, you're misunderstanding. The Ford factory installed some cams that way to
meet newly-imposed governmental emissions regulations. Replacement cams are
generally marked in multiple ways so they can be installed at 4* retarded or
straight-up.
