Would performance pulleys do any good for my 351 windsor?? are they worth buying? I know they are cheap but are they worth it?????

 

Remember. When you slow your belt down, which is what you do by getting undrive pulleys, you slow down your alternator, your A/C compressor, and your power steering pump. You'll see a little more pep. But not enough(in my mind) to make up for the lost energy from your alternator and all that.

If you want more pep, do the timing bump. A true dual exhaust with long tube headers, get more air in the engine with a k&N air filter and drill a couple holes in the bottom of the box(what I did). Electric radiator fans will do a lot. Good oil. Seafoam every 10-15 thousand miles. And run some injector and fuel system cleaner every 3rd or 4th fill up. Does wonders for me.

 

You'd be surprised how far a little TLC will go on these engines. When I bought my truck it wouldn't spin my old 31's. But I've don't nothing but engine oil flush when I bought it, seafoam, and stuff I mentioned above since I've owned it. And it will spin my 33's all day long with no performance mods.

 

Well my truck spins the 36" super swampers it has on it now with no problems it has no exhaust after the hollowed cat and there is no performance on it that I know of

 

I'm trying to find small cheap things I can do for now and oh yeah the belt is a smaller belt that fits all the pulleys except the a/c so that's not turning at all

 

On top of what WonderTwin1 said...

IMO, underdrive pulleys are an absolute waste of money … here's why…

because, yes, you take 2 lbs of rotating mass off the drive line but in the BIG PICTURE it's a drop-in-the-bucket. Think about what & how many more rotating objects are between the rubber on the road and the injectors…tires/wheels, brake rotors, axles, drive shaft, crank cases, transmission gears, crank shaft, rods & pistons…

so in the big big big picture (also known as reality) you are reducing your rotating mass by a tiny percentage. The time & money is better spent in other areas.

 

Sounds good to me haha no pulleys then haha

 

pulleys are for high performance motors seeing track time...

I'm curious to know if your truck is running a stock cam or not to be honest.
get an aftermarket intake if you'd like to see some gains.

just remember all we have is a basic air pump... more air in + more air out = more power.

 

How would I tell if there's anything done

 

get a sound vid I guess... everyone that is stock will know right away if you've got a cam in it.
