Makes you wonder how much power actually comes from the "heads". Seems that about 25-35hp comes from the intake and cams. That would leave about 25 for the heads themselves. I picked up 70 hp but my heads were ported and polished. Great thread!!!!!
He just has the NPI cams and look at those numbers! Especially after the old intake ran out and the new one kept going. If he gets that a/f fixed he will be in hog heaven. There is more there with just the intake, but I bet you could see another 10-15 out of it if you added in the cams.
Some people who know a lot about this think the heads alone really aren't worth much if anything. The PI headswap will up your compression and you will definitely get a boost from that though. The initial investment and bang for the buck factor is really attractive for this route and with just the intake and cams you don't need to run premium all the time.
I have a pretty much stock 98 GT that I had on the dyno a few months ago to get a baseline. Nothing else has changed and I will be putting the PI intake
and cams in mine first. It will be a few weeks for me and someone will probably beat me to it, but I will let everyone know what the new numbers are after I am done. I bet someone will already be there this weekend if not the next few days.
I love your attitude too man. Says a lot about you. You know what you have and I am sure it was worth it to you. A lot of people are naysaying because they spent the big bucks like you did and I think they are trying to feel better about it. I have been reading a lot of stuff about how you don't want your ports mismatched and you will "blow" those gaskets out. blah, blah, blah...
If these people saw some of the stuff we worked with on the early "musclecars" it would blow their minds. I have taken factory intakes off of cars that had as much if not more mismatch.
Bottom line, if it works, it works. The numbers don't lie. For those who want to take their time and do it right the reward is there. You won't be blowing anything out unless you put it together wrong and didn't get it sealed right in the first place or if you use forced induction.
Kudos to those who were not afraid to try something new.
