I know this isn't a mustang, but I figure you guys will know better than anyone else on this site.

My brother has a 1969 Torino with a 351w and he is looking to increase performance. Right now it has a 2 barrel carb and the stock exhaust. Right now it has a 3 speed automatic and we plan to bolt in an AOD.

He is wondering what a good 4 barrel carb would be, a good exhaust set up, gears for the rear diff as well as a high flow air cleaner.

Any help is appreciated!

Thanks

Here are some pics for those interested:

 

500 cfm holley carb with electric choke, 4 bbl intake manifold (more expensive the better, generally speaking) magnaflow or flowmaster exhaust should at least get him going. What rear end is in it?

 

Its a 9". I am unaware of the gearing right now but it is probably stock

 

in my opinion, 500 cfm is too small for a 351. something closer to 650 should be a little better. if your going AOD then you can go pretty low on the gearing, but 3.50:1 is a pretty good setup. i dont know what the stock stall is on the torinos but the mustangs were around 1800 i believe, changing that would help out too. get a nice set of headers, tri y's arnt too much and they are good for low rpms on the street. a nice dual plane manifold, they arnt too much either. a tune up does wonders too, new points, condenser, spark plugs n wires. you could pull that power steering pump off and get an electric fan for less stress on the crank, but thats not necessary, just an idea

 

I'd go with a Holley 600 and Edelbrock RPM intake

 

There are a lot of opinions for the carb size but this might help in your decision.

Keep it under 5500 and a 500-600 is perfect. Hope I helped.
