Ford engine questions. Small block Ford

I currently have a newly rebuilt 289 bored .030 over, turned crank, speed pro skirted forged pistons, all internals balanced, with ported and polished e7te heads, rpm air gap intake, holley 600, hooker longtube headers, msd pro billet dist., 6-al2 box, blaster 2 coil.

first question how much power should I get out of that 325-350???

second I have $2500 I was wondering if it would be better to build a new 347 stroker with tfs heads for 2690.98, or supercharge it for around $3000. Or stop worrying just drive it and spend money elsewhere

Its kind of silly to want to start over and build a new motor since this one has just been built and not driven yet, so I see no point in redoing it.

Do you think it will run good in a 68 coupe mustang with 2500 stall c4 and 3.55 gears or am I just worrying

The deck was trimmed .010 and heads were milled and the pistons at flat top the builder told me I would have around 10:1 compression. I know it's a pbm cam around a .498 lift can't remember other things it sounds great and it winds up to 7000 rpm all day long. Just hasn't moved under a load yet

Lol that's what I was thinking!!! My mechanic says it'll have plenty of power for this light mustang and not to get worried about numbers it's only 2450 pounds with the gutting they did

i think over 300 horse with that set-up is generous.not to disrespect at all.But i ran a 289 bored .30 over,balanced,an autolite 4100 4bbl,a 260H cam,Pertronix ignitor ignition,a pair of 69 351W heads D00E that were mildly ported on the intake side and ALOT on the exhaust ports..ford exhaust ports suck on factory castings.And i was using a dual plane weiand aluminum intake manifold.I had the engine in my 1965 falcon convertible.I had it on a dyno and it peaked at 273 horsepower.Not too bad at all considering i didnt really know what i was doing thoroughly.I do know that at the time i was building it,I wanted to get to 300 horses maybe a bit.But it wasnt going to happen with the pieces i was using.In order to get 300 or more hp.I needed to lay out ALOT of money for aftermarket heads,roller cam/rockers a better intake manifold etc.I ran a 4spd for awhile and i was using a 9in rear axle from a Bronco with 3.73's She got out of the hole FAST!!.The car was no slouch for sure.And at least one 396 camaro got a nasty surprise.In my opinion you need better aftermarket items that go together a 'system' and do your homework on cams,heads etc it wont be cheap reaching 300 horsepower or more

i wanted to add,that i had 9.5 compression ratio on the cylinders.I had some cheapo brand X long tube headers with an H pipe all the exhaust was going thru 2'in and quarter exhust and cheapo glass packs.And the best part was when it was being dyno'd the tuning guy took a few minutes,timed the engine properly..i didnt,i had guessed at it..sounded good and smooth,So i must have been 'dead-on'..nope,He also changed out my 'champion' plugs for a set of autolites,tinkered with the gap and the pertronix..i picked up 11 horses right there in the dyno shop..all for the cost of 8 plugs

because the 289 will rev quite well,why not leave it alone? invest in 4.3 gears and an over drive transmission.Its a lot of fun having a little under powered car that can destroy tire melting big blocks that drink gas and eat tires

The headers are super comp longtubes exhaust is 2.5 mandrel bent all the way back into magnaflows and dumped. I need some better plugs I'm sure. I wanted to get new heads but it almost seems pointless honestly. And greazyball was that on motor or at tire ???

that horsepower was at the engine.Somebody posted here that an undepowered engine can be helped with an overdrive and 4.3 gearing.Thats true to a point.My falcon was quick,eventuallyi added 4.10 gears and more than one mustang/chevelle/nova that had more power and better motors got spanked by my 289. and 273 horsepower is nothing to sneeze at.I like the 289 its my favorite engine,But if you are looking to build up to or beyond 300hp I would take advantage of the later 5.0 roller cam motor.with fuel ijection.Those motors will spin well into 6,000rpm..whereas my little 289 was huffin n puffin at 4,500 too 5000 and thats always been a restriction on fords i think..they didnt wind up like a chevy 327/350 unless you did some work to the heads.if you want to stay 'old school' then yeah build a 289 still a good motor but i think it will be an uphill battle trying to get it to or above 300hp.it can be done without doubt but there are better motors to start with.I read an article a long time ago called '8 tenths of a second the hard way'..i think it fast fords and mustang mag..anyway the editor took his 1990 5.0 mustang and added early casting 289 heads to his 1990 motor he had done a backyard porting job on the heads and added the then new roller cam/rocker adapters to the heads..he chopped nearly a whole second from his 1/4 mile times.at the time aluminum heads were all the rage but very expensive...so he wanted to do an article for the low-buck guys

I'm new to this forum, but have been drag racing........and some street racing Fords for almost 25 years. My current car is 70 Maverick with 408ci.
To start off with, like some people have said is to drive it..............if it's too slow then a quick 30/40hp would be to deep six the Ford heads and go with aftermarket heads..................SBF's will make hp, but not with the factory heads. I had a 64 Comet with 289HiPro 4spd and 4:30 gears, had a Schneider.........this was over 30 years ago, but think is was .544 lift.....anyway I had the 69 DOOE 351w heads that had a ton of work done on the exhaust side and the motor was just under 300hp at 7200rpm..at the crank. Fast forward to this past May and my 408 made 650hp at 6800rpm.
Heads/cam/compression are the key to making hp in a carb'd SBF....IMHO

my point about factory ford heads was that overall they dont flow as well as say a chevy head..as for HiPo heads Shelby himself said in order to get more power from the HiPo heads they still needed alot of work in the valve areas,especially the exhaust side.and and at the time i used the 351W D003 heads,they were the best option for increased hp..nobody was making aftermarket heads for the 289/302.HiPo 289 heads were then as now non existant and if you did find some they were $$expensive$$ and out of reach for the average guy looking to increase horsepower.i know i was tired of seeing the chevy guys at the strip able to twist a 327/350 up to 5,000-6,000rpm no problem and those engine were not anything exotic..my old 289 was done making power around 4,000-5,000 the biggest problem was lack of good flow from factory cylinder heads..later GT40 heads,aluminum heads etc solved some of those problems..but 300 or more horses from darn near stock heads is difficult. I had done pretty well to squeeze 273hp from my 289 with the pieces i used..to get more needed better designed heads ..like what came on later 87-93 302's
