4- barrel intake manifold, dual exhaust, headers, camshaft. Any more will require removing heads, pistons, etc. The engine should be in good shape before you start, with good compression on all cylinders, good oil pressure.

 

A lower geared rear end will give a real boot in the pants, but makes cruising down the highway problematic, unless you also install an overdrive transmission.

Thanks can you recommend which carb would be best .

I don't know what you have readily available over there. Without any other performance upgrades I would start with something in the 600 to 650 cfm range.

For ease of use and price I don't think you can beat the Summit Racing carburetors.

Otherwise, I would go with a Holley.

I don't know if you have an automatic transmission, or not, if you do you'll also have to get the kick down lever for it.

We like our Edelbrock 600 carb, it works great with my combo but did require a bit of tuning to get it really dialed in. I have summit racing 4.11 gears in my car now, they are a blast in town but if you drive 60+ alot I wouldn't recommend them. A 3.25 ratio would probably be the ticket here.

Nige,

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

When a man is in the woods and talks and no women are there is he still wrong??:P

How can i find out this information

in 1973 the mustang with a 351 engine would have been a Cleveland and not a Windsor. Easiest way to tell is look at the front of the engine where the distributor is. Does the cooling hose enter directly into the top of the block next to the distributor or does it connect to the intake manifold? Cleveland's have a dry intake manifold so if the cooling hose enters directly into the clock it is a Cleveland. If it is connected to the intake it is likely a Windsor. Post some pics of the front and we should be able to tell you for sure. No one wants to see you buying parts for the wrong engine.

73 Grande H Code. Headman long tube headers, T-5 Transmission, 3.70 Traclok, Lowered 1" all around, Aussie 2v heads w/ 2.19 intake, 1.71 exhaust, screw in studs, full roller cam 608/612 lift 280/281 duration LSA 112, Quick Fuel 750 CFM double pumper, AirGap intake.

do you see the hose coming from the top of radiator to the engine? The fan shroud in this pic blocks the view of where it terminates. If it goes into the top of the block it is a Cleveland. If it goes to manifold it is likely a Windsor. Can you take a pic close up of where it terminates.

Based on the size (width) and how the coolant hose appears to terminate I would say it is a Cleveland.

Looks like Cleveland valve covers.

Ah yes the other way to determine. Cleveland valve covers have 8 bolts. A Windsor has 6.

That is a 351C. No 351W's had that shape valve cover. Besides the already great suggestions on how to ID this engine, you can also look at the fuel pump mounting bolts. The 351C has vertical mounting bolts and the 351W are horizontal. This and counting the valve cover bolts are easy peasy!

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.

Nige,

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?

Will jack car up weekend and find out gear ratio

 

65mph not very often / just want to pull away fast

 

mountain driving never none around where i live

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.
