Hey guys, I'm new to the forums and I was hoping someone can help out here in this little dilemma.
I did some research in the forums here to see if someone else had already asked/answered this question but I haven't had much luck getting a specific answer so I'll try it on my own topic.
I have a 1969 Mustang Grande with a stock 351W and my dad and I have decided to add a new 4bbl carb and intake since apparently everyone changes out the Windsors stock 2bbl carb with a 4bbl unless they were keeping it original (according to a couple mechanics we talked to). So I'm just curious what you guys would propose we do. I'm not looking to make my car into a dragster or anything but I would like to have some good horsepower (280-320 range).
I remember coming across a topic on this sight that someone talked about the Edelbrock Performer RPM intake but if there are others too please let me know.
I'd run a stealth over an rpm on a stocker, summit and professional products make a stealth clone for a lot cheaper and they work great, I have a ported one on my 408, as for carb 600 cfm is fine, a road demon 525-625 would be optimal and probably give the best economy and performance out of all 600 cfm carbs.
the factory ford C9OX-9424-A Buddy Bar aluminum intake is said to be the ultimate from idle to about 6000 rpm. its got a huge plenum and is a lowrise and came stock on the 69-70 351W shelbys. a few weeks ago i bought a good one at the pomona swap meet for $200.00. i am going to put it on the W in my torino and disguard the performer thats on it. i have seen them from time to time on ebay and they were sold over the counter from ford and came with either cobra ,ford , or shelby letters. look at the water jackets to make sure they are not corroded away. a 750 cfm "vac secondary" is a good size for your W.

without changing the cam and/or heads you should be able to pull maybe 250hp max with int/carb/headers/exhaust and a good ignition, add the right cam to the mix you could hit 280 hp, add good heads and a matching cam for the combo 350-400hp can be done.
The summit carb is a improved holley 4010 which is based on the autolite 4100, the annular boosters are a big plus adding low end tq and throttle response other wise the best carb for the money is........Barry Grant 4282020VE Demon Road Demon Carburetors
If you don't like tuning carbs get a 600 cfm Edelbrock. Most of the time it is bolt it on and go for a stock engine.
