That one, I've got no idea

You'd have to do some digging on a truck performance site... performancetrucks.net will probably be able to tell ya.

Heck, for all I know your current heads might out flow the vortecs
But it would be nice to know for sure, right?

exactly. My performance resource told me the difference wouldnt be worth the money. But other performance shops are tellin me to go vortec.

You'll have to do some digging then, to find out for sure

You could always turn it into a 350

This is all true. I like the Vortec head idea best before you get to giggle juice. Even the nice camel humps are old school these days and sure not the elite like they used to be. GO Vortec heads. JMO, but I also am not a big fan of NOS. Seems to really shorten the longevity of a motor, and I like longevity. I do prefer all motor, but I have thought about trying the juice just to do something new. I actually have a little logo, many probably won't like.

It is impossible to predict the gains without knowing more about the heads. Just saying they are ported doesn't really mean anything. I have seen ported heads perform worse then stock heads.

Vortec heads are a much better design then the double humps you have and have a lot more potential. BUT, if you have a good port job on your heads and just stick a set of unmolested vortec heads on it, I wouldn't expect big gains.

Good heads are the key to horse power. It really all depends on your budget. Patriot Performance makes a good set of vortec heads that would probably liven your ride up more, but I believe they are really intended for 350+ Cubic inches. Not saying you couldn't run them but it just means you're going to have to twist it harder.

There are a lot of ways to go here, but a question I have for you is, how long do you plan on sticking with that baby motor? The reason I say that, is if you are always planning on running only 327 CI, I would give you one set of recommendations. If you plan on stepping up the cubic inches in the future I would give you another recommendation.

I use to be the same way. But then I tried it. I don't recommend trying it if you don't want to keep it up.

Crap, I would spray mine loading it on and off the trailer if I could

I understand that view, but when you try to build a car that can have good street manners and be fast on the track NOS is about the best way to accomplish this.

The torque a nitrous motor makes is UNREAL!! It is pure addiction!

I'm gonna keep my 327 till it blows. I want to see just how fast i can push it. 10.9 is my goal for it

Well if that is your goal then I would get it to hook #1 and then put about 100 shot on it and you will probably be in the 10. 70-10.80s

Your biggest issue is going to be traction with that light truck when you start making a lot of torque.

There is no reason that set up correctly a Nitrous motor will not last as long as a blower motor.

thanks for the advice..
