[Nige]

Thanks for the info all it is a cleveland it has vertical thermo housing , 8 bolt valve covers and bolt top and bottom fuel pump.

Don't trust what anyone says in an ad. Believe what you see. Now your original question. Without getting too involved in major engine work. A good upgrade would be as follows....

4 bbl intake

4 bbl carb (prob in the 650 cfm range)

Headers

Depending on what the rear gear ratio is an upgrade here would be a big improvement.

Hi All

1973 mach 1 with 351 Windsor 2v

what is best way to make quicker for road not for drag racing , will 4 barrel carb do much , any info would be great .

Thanks Nige

Nige,

It that a replacement engine or a Mexican model? No Windsor in U.S. Mustangs from factory.

what is your rear gear ratio?

do you often drive for more than 30 minutes at 65 mph or faster?

what is your average speed during "spirited" mountain driving?

Is there a sticker inside on the drivers door? this will show you the axel, trans, and engine code along with original color and interior trim and color. If there post a pic and we can decode it for you.

The weakest link in any Windsor engine is going to be the heads. High Quality heads such as AFR, Edelbrock, Trick flow, combined with the other suggestions above will maximize the fun factor.

Read previous info in this thread. He has a Cleveland not a Windsor.

Never rely on the sticker to be accurate unless you are the original owner of the car.

ok, i just didn't understand your statement below clearly.

"what is best way to make quicker for road not for drag racing , will 4 barrel carb do much , any info would be great ."

As was previously mentioned, numerically higher gears will increase the acceleration rate at all speeds, therefore, this is the single most important change. Installing a 4v vacuum secondary carburetor will do nothing to increase power until around 3500 rpm. A mechanical secondary one can give you more power sooner as long as it is not too large for the application but it will still not get you off the line much faster.

Going up 1 step in gear ratio (like going from 3.25 to 3.5 or from 3.5 to 3.7 etc) will be a moderately noticeable change, but not a huge day and night difference. Going up 2 steps will be very noticeable. I would probably not go up more than 2 steps for your application.

Never rely on the sticker to be accurate unless you are the original owner of the car.

Agree, with a further thought on your statement. I had to remove my original door data label during the complete rotisserie restoration of my vert. I did not want to do it, but, unlike earlier models, this was a glued on label, no way to properly restore the car and save the data label so that it did not show that the car was repainted... I was able to document the original label on the car before removal, as well as save the original label when I removed it from the car. As you know, it then must match the dash VIN, the fenderwell partial VIN's, the buck tag, the engine ID and transmission ID #'s, the build sheet, the Marti report (which for me is the weakest ling in all of this), the factory invoice and so on... 

Its a tough call when you take a car down to a point where it will be completely media blasted or chemically dipped... all one can do is document for future proof of what was done to a once original car... My experience in the matter...

I love my 4.11 gears with traction lok, it gets out of the hole real fast now. My car is driven around town 95% of the time so no problems or regrets here. I did the install myself, it was a pretty straight forward job for an experienced gearhead, no pun intended.

HI All

Wow, that is beyond lame. So a 3.25 will make a fairly noticeable difference and 3.40 and 3.50 will make even more. If you install 3.25's it will feel like you gained around 50 hp. If you install 3.50's it will feel like you gained 75 etc.
