Thread: Wanting to upgrade a 289 in a 65 Galaxie

Tweet

I may go with Jeff's ideas. Once upon a time I wanted a street machine. But now since I got some little ones I think a nice cruising engine would be the best way to go.

Instead of using aluminum heads what if I was to go with a set of GT40's?

Not a worthwhile investment,give this a good read:Five.Oh Info : The Ultimate Ford GT40 and GT40P Cylinder Head FAQ also both the aluminum heads and the 289 heads have an adjustable valve train,the GT's do not as you can see the HP gains would be minimal too, in fact possibly less than the stock heads because the 289 heads have more compression.More education here: http://www.mre-books.com/interchange/interchange5.html Now that being said since the early 289 heads are almost the same as the the 289 Hi-Po's there is a budget trick that has been done to improve flow when you get that valve job done you can use these:1 84" Intake Valves SB Chevy 305 V8 SBC Small Block Stock Steel Set of 8 | eBay You do not want to go larger because it would involve more machine work you can do some port matching and minor porting to the exhaust as the exhaust is a weak link with stock heads,this is where the aluminum heads really pack some of their punch,but bottom line the Flo-Teks are the real bargain.Like most of us down the road we think this is fun but "more is better" those heads can be swapped on to a 351W

I'd say you're making a good decision, all things considered.

you'll probably need that special bolt set for using 7/16 bolts thru them 1/2 holes

These adapter bushings:http://www.summitracing.com/parts/edl-9680/overview/ 289-302 head bolts are 7/16" most aftermarket SBF heads are drilled for 1/2" bolts used on 351W's.

They aren't to far from me.. if needed, I can go put an eye on'em.. maybe even help get them into ups or??? If I wasn't content for the moment, I'd snag'em for a future project. They are listed as a big port so that should help you out on a street motor too.

I would love to have them. But maybe someday. For now I'm going to have to go the cheaper route on the engine and use some of Jeff's ideas. I'm going to have to spend more on paint and interior first then maybe after that then I could always swap out the 289 with something bigger and better.

Is the current 289 still running ok????????????

It is, however I noticed some blow by coming from oil breather. I am hoping that's just the vacuum line coming from the pcv valve. Gonna check that out as soon as it warms up again. Other than that it sounds smooth and seems to run good.

Drive it---

lol i will. i just want to give her some pep.
