1966 A Code 289 Performance upgrades

I'm looking for some help and what upgrades to get for my 289 engine. I looking for a combination of new carb, cam, and intake to increase horsepower but also not break the bank. Also wondering what a good exhaust set up would be to give it a more aggressive sound. I am looking to swap the manifolds for headers.

Any suggestions would be great.

Hi,
No doubt, once the general population wakes up, you will get an ear full. First, ask your self....do I want a nice street warrior? A street strip car, or a drag queen? After this, how much are you will to spend? How good are you at doing your own wrenching? There are many of s here willing to help, but, you need tools and your need to answer those few basic questions. In any build, as you are asking, number one is answering my first question. Then, respondents will go from there. So, answer that "first" question, then, research heads, as these will be your first purchase based on your answer, followed by the cam, intake, rear systems etc.
Welcome and good luck!

I don't intend to turn this into a drag car, more of just making a road warrior knowing it has some power on a nice cruise. I would also like for it to have hot rod sound to go with the performance.

Hi again,
OK, wanting to build a nice "road warrior" is a good first step. Next step, is to research all of the components, heads, intake, carb and cam, either as piece parts or as a package to determine what's best for you. If you have the experience and knowledge, you can buy the piece parts individually and assemble. If a little hesitant, buy a combo package like what Edelbrock sells. Being a street warrior, yo want to build an engine that makes "torque". This is what you will feel when you stick your foot into it from the street level. Big "HP" is made in the higher RPMs and you ain't going to be cruising up there all the time. You'll need headers and dual exhausts, as well.
Also know, to get the maximum benefit, you may need to add a higher stall converter (auto tranny) and a lower rear gear, perhaps a 3.25 (good with C4s) or 3.55 with a eventual move to a T5.
good luck!

look to Edelbrock for intake and carb...any decent long tube headers will be fine...for cam, look to Comp...if it was my car I'd get modern aluminum heads first, it's really what holds that motor back from making real hp

If you are running a C4 transmission DO NOT GO STEEPER ON GEARS! Just a word of advice from someone we spent THOUSANDS do and redoing that very upgrade/
downgrade. Research my old posts on the subject for reference.

I agree with Lizer, do your homework and figure out what you're really looking for and really what your budget is. Once you've done that you'll be surprised at how much proven data is out there from previous builds with dyno sheets to prove it. Sounds like you're on the right track, just by asking and that you are looking at the system from carb through exhaust.
My big questions for this thread:
1) what's the budget?
2) what trans are you running?
3) what's your level of ability?

I agree with the previous 2...heads will make all the mods really work. The old heads just don't flow well, and will be the big constraint. And the rearend ratio, transmission is a huge consideration. Lower the ratio to be much quicker, but if you are running any of the original transmissions (1:1 3rd or 4th) be prepared for high RPM highway driving.

Just a final thought, I'm doing a budget performance build and am installing later model heads instead of aftermarket aluminum to save money (GT40P). they cost $80/each as removed. Much better flow without robbing the kid's savings fund. Headers more pricey for these though.
Good luck

OK a little more information about car/engine, my dad and I bought this car to have a little winter project to have to drive around in the summer. Were not making this a daily driver. It has 289 in it with a 4-speed manual trans. I'm looking to stay in $1500-$2000 range with upgrading the engine so I hope that helps with parts recommendations.

Hi,
The typical low budget engine mods for a street ride, is adding TRI-Ys, dual plane intake, dual exhausts, 600 CFM carb, and swap the points for a Pertronix. Then a thorough tune-up.
The really crazy stuff can come later....?
Happy Motoring!

Ok been looking around online for products, looking to find out who makes some good Tri-Y's. I see some Pertronix and Scott Drake thoughts on them. Also Ceramic Coated, Stainless Steel, or Black?

How are the Ford Racing intake manifolds compared to the Edelbrocks.

Hi
I bought my TRI-Ys in about 1994 from Mustang Unlimited and have had them coated twice. What can I say?
