289 mod questions

I was wondering if it would work out alright if i get the edelbrock performer rpm package for my 289. This includes 750 cfm manual choke carb #EDL-1407, performer RPM intake manifold #EDL-7121. for now then the cam and heads later on. Im just wondering if that will give me any probs or concerns or if i should go for it. Right now its all stock 1967 mustang 289 2v. Thanks for any feedback.

Re: 289 mod questions

the 750cfm carb is way to big for a stock 289 plus ive read on other forums that it is not that good a carb compared to to the smaller 625cfm elderbrock,carter carb which are a great carb for setting and forgeting .
Go for a holley if performance is your thing but be prepared for constant tweaking.
Dual plane manifolds are the way to go on the street

Re: 289 mod questions

750 will be massive overkill until you start doing cam and heads, then they would want to be fairly serious items.
If you want a mild motor even a 600cfm would be on the big side

Re: 289 mod questions

750 cfm is way too big,go a 600 cfm holley vac sec,and the performer rpm manifold,will work good
with a stock 289,and be enough if you do cam and headwork...

Terrorising a crap driver near you!

Re: 289 mod questions

i've got a 289 performer on my 302, and only ran a 650 vac. And its a pretty sick engine. 11:1comp, ported, big valves, big cam, extractors, elect ignition. Up for sale if anyones interested, spent close to $7000 about 1 1/2 year ago. But unfortunatley was unemployed shortly after fitting it, and couldn't afford the fuel bill driving 60km into town and home. $5000 for the engine $6000 with a stg2 c4 & 3000 dominator convertor. lifted front left off the deck on a hot day changing 1/2 in an XY.

Re: 289 mod questions

I had Wiend Xellerater and a little 465 Holley [smallest 4 barrel] mild-ish cam and ported exhaust on heads and it reved it's head off, built for torque at low rpm...

I have a 289 with a weiand xcelerator (I didnt put it on ) and an edelbrock 1406 600 cfm carb (vac sec). Given that it has a stock (I believe) cam, I was thinking maybe the carb is too big... Would I see any increase in power by goind down a size or two in carb?

Re: 289 mod questions

My 66 Mustang is a 289 "A" code.

I run a Edelbrock 4FB inlet manifold, Tri Y extractors/Headers and twin 2 inch system.

My car originally had a 500CFM edelbrock 4 BBL carb on it.

I made the mistake of going for a 600 Vac Sec Holley. Big mistake. I ended up putting a 465 Holley and she works a treat on the little 289.

Used to be Mustang1966coupe.

What were the symptoms of the change to the 600cfm? Loss in bottom end power?
