1.
are they any good would it make the engine bay hotter?


2.and i need a good nitrous system with a small bottle not to big. its going on a stock 4.8.

what would make difference a cam or nos? for a completely stock engine

 

I have the coated pacesetters and I've been happy with them so far! Decent improvement performance wise and they sound good. My engine bay seems to be the same as before with regard to engine bay heat.

2. How big of a shot would you run with the nitrous? Nitrous would be the biggest difference as a mild cam will give 30-35rwhp. Plan on using a bigger stall converter? Plan on tuning it?

 

OK how or whats a stall good for ........yes i plan on tuning it of course.what would hurt the trans less? whats cheaper and safer?


my goal is 280-300.....what is it pushing stock whp?

 

Then I would suggest a Circle D 278mm 3000-3200 stall, Tune, and then a Comp 212/218, TR 220/220 or Comp 216/220 cam with that stall. All that along with the pacesetter longtubes. That would put you at your goal easily i would think maybe into the 300's at the rear wheels

 

would it overheat with the cam? would it hurt the engine alot in the long run and trans?

 

stall brand is circle D. what brand of camp???

 

whats more safe for the truck nos or cam? would it overheat wiht the cam?

 

cam and no it wouldn't overheat

 

If those in fact are the headers you're interested in, they will not work on your 4.8L. They're for a Gen II or older smallblock.
