How well do these perform on nitrous engines? Anyone have any personal experiences with them?
just heads up when I bought them they were like 80 bucks apiece cheaper on jegs
As an option to those I have a brand new bare pair of small bore All Pro LS7 heads I may be willing to part with. These are as cast, even with that I'm pretty sure they would outflow those LS3 heads and would do even better with a little bit of work. Just in case...How well do these perform on nitrous engines? Anyone have any personal experiences with them?
I do have them on my 408. As far as data, I can't really say at this point. ever since I got the engine in the car I'm fighting traction issues.Streetknight has them on his new 408 i believe.
Yes, the chambers were softened. I bought them used and they flowed 360cfm and were like 6 years old. Mike Duke did the port work. I hurt them, so got some new ones on the way.I just got my CNC LS3's the other day from a guy on tech, they seem pretty nice.. I think I will run them as is for now, and try and improve on them over the winter..
Blackflag, what CC chambers? Did you chamber soften them?
I am going to chamber soften mine, and put a fresh valve job on em.
Solid roller deal?Yes, the chambers were softened. I bought them used and they flowed 360cfm and were like 6 years old. Mike Duke did the port work. I hurt them, so got some new ones on the way.
Don't remember CC, but was close to 13:1 with them. Quench was tight because they had been cut a couple times after pushing water from previous owner.
I think my new set will last a long time with no problems until we REALLY get after it. I had too much timing in the tune up or the old set would probably still be fine. Working with a nitrous tuner and had my intake flowed so can't wait to get it back out. Also went with a new Jesel rocker setup vs the old harland sharpe setup I had that kept breaking shafts.
