I am starting to build my 66 fastback as a streetable fun (350-400hp) car to drive. On the list so far is a set of Grnada brakes, t-5, Explorer 8.8 rear end with 3.73's and disc brakes (need some help on spec to narrow it to), and a 289. Any input would be appreciated especially in cam selection and heads.

No problem with the horsepower request.
Just go here and write a check for $25,000 give or take a few dollars:

Let us know how the project goes!

You'll need a stroker to get streetable numbers like that.
For the other questions, a reasonable attempt at a search will work wonders.

Granada brakes?
Sounds like a great project. Not sure why you want to waste your time doing a Granada disc upgrade? This old school upgrade uses old school technology which has been replaced with much better offerings today from vendors like SSBC, Master Power Brakes, Baer and even Mustang Steve's late model Cobra brake swap kit. You should look at your options before going the Granada route in my opinion.

You guys think it's really that hard to get 350hp at the fly? He didn't say to the wheels.
Just wondering, cause I'm looking at the book "How to build maximum performance Ford V-8s on a budget" And they have a 302 making 454hp at 6100rpm
Block: .030 over, decked 005
pistons: .030 over flattops
compression: 10.5:1
cam: comp cams 282 hydr. roller
lifters; hydr. rollers
valvetrain: compcam roller rockers
Heads: AFR185s 2.02/1.60 valves
intake: Edelbrock Vic Jr.
carb: speed demon 750cfm
exh: 1 5/8 longtubes
Maybe the 302 recipe in the book is BS, but can 350hp from a 289 be that hard? Or is the 289 really that diferent from the 302 that you couldn't expect 350hp from a similiar combo?

Hey Thanks for all the help for the new guy! I did mean at the fly. Oh and Historic went to Cobraautomotive and apparently motors are on sale today "365 dyno-tuned horsepower, ready for installation in your favorite car. Built by custom order only, $10,500.00" not $25000
. Thought you were the mustang guy to see on how to build on a budget.

I don't think it would be that hard to get 400 FWHP out of a 289. My 302 with 9.5:1 comp, ported '70 351W heads, HO cam, headers and a 4 bbl will do around 340 FWHP. Now, granted, I did get that number from engine analyzer (which is reputed to be fairly accurate), but with aluminum heads, a bump in compression, a bigger cam, and a better intake, it should do around 400.
That's what I'm thinking. My 5.0 comes out to 362hp/346tq on EA3.0, with SAE temp. & humidity selected, and it's basically identical to yours, but with a TFS cam (.499/.510lift, 221/2225dur 112LSA), and PerformerPRM intake.redhotcomet said:
Step it up to 10.5:1, AFR165s, and a Comp 266HR, and 400FwHP should be reasonable. Bear in mind though, we're talking about a 289, not a roller 5.0. The shorter stroke of the 289 will give you a little less torque, and the typical flat tappet cam will also affect torque when you get into looking at cams big enough to push 400HP. You might have to look at a soild roller, one of the bleeding edge Comp cams, or a custom flat cam, but it can be done IMHO

Ok it sounds like some of you think the 350-400 fwhp can be achieved how about some input on a recipe. This is what I am thinking. For heads-- ported with 1.94 intake and 1.69 exhaust, intake--Cobra with a edelbrock 600cfm- maybe up to a 750cfm cam? --
Crower #15212 228 duration 530 lift and flat tops. How about the rest of the car?

I don't think ported 289/302 heads could do it, but with the larger intake port of the 351W heads, and how those heads respond to porting, I think you could use them. I will point out though, if you're shooting for a 400fwhp 289, you're gonna need all the advantadges you can get. You'll need some seriously good heads, a pretty trick hyd. flat cam, and the best street intake you can get your paws on. While everything you mentioned is good stuff, it's not 400hp 289 good.
I think a Comp cam with some of their newest lobe designs (maybe mix and match from the newest releases of the XE series?) would be the ticket along with a vintage TorkerI or maybe a new Wieand eXcellorator intake (both very mild single planes, proven on the street). A 600cfm carb and some headers to finish it off should make a nice motor. Some 3:55 or 3:73 gears would be perfect with the T5, for a street car.

I agree with 5.0ina66 But for street I would definatly stick with a dualplane intake as they will usually outperform the singles in low rpm situations (street) and in a intake shootout article I read a while back (forgot which mag) the Edelbrock RPM air-gap intake was only a few (less than 5) hp less than the victor seires at high RPMs
400 hp out of a 289 is not a pushover easy task but it is by no means impossible

Points to ponder:
1. Will it be STREETABLE hp? People's definition of 'streetable' varies, but my definition has become more and more narrow as I get older
2. Not impossible to get it from a 289, but will take quality parts, assembled expertly, and most importantly TUNED expertly. All this = $
So, it begs the question - why not use a stroker to get the same with less $, less hassle, less wear-and-tear (more longevity?)
Wound-out, high-HP, roadracing 289s are extremely cool...but my position is one of the guy leaning over the fender looking at someone else's

I disagee. A stout single plane, like the VicJr. WILL kill lowend power. OTOH, the Torker has almost dual-plane like lowend; about 10lb/ft loss over a PerfRPM. It's a 289, face it, it won't be a torque monster, and you're trying to hit 400hp on the street. Sacrifices must be made, and if you have to trade 10lb/ft on the low end for 25hp, then so be it. I've seen people running even more drastic combos on the street, and murdering low-end in their search of the almighty HP, but 10lb/ft is peanuts in comparison to what they give up, with huge head-flow numbers and a big single plane. You could make up the small SOTP difference in the lowend with a set of 3.73 gears, which, come to think of it, may be nessecary to keep from lugging it in 5th anyway.tylerrocks said:
