I can see you hitting about 315 tops w/ heads+cams (but also the supporting mods like LT's, o/r midpipe, etc)

And what do you guys keep talking about when you stay "stock bottom end" You are not worrying about messing your motor up are you? Because If you are worried about 325 rwhp on the stock bottom end, then I am crapping my pants right now lol ;-)

They arew worried about the rpms required to get to that hp level, the rods wont like it much....

WannaBeGearHead

Exactly. With heads, cams and his bullitt intake and the 320hp goal to get close to that the shift point could end up being very high which the stock rods won't like and probably won't hold up long.

If you are 100% going to stay on a stock shortblock without a piston notch then you can get another 10-20RWHP with the TFS heads below 7000RPM as you can fit a better cam, but once you notch the piston the playing field gets leveled really fast with the PI. As for easily hitting 320RWHP with TFS heads, that has not been my experience nor of most of the dyno shops I deal with.

Don't say that!!! lol

I do like his taste in cars though

Unless shops are fooling with the dynos there is plenty of numbers out on the net now. One guy on moddedmustangs put down 350 through an auto..

^Sh*tting his pants right now....

lol, I think nick knows about that car. I'm pretty sure he sent that guy a set of custom cams for it before anyone was making TFS specific cams.

nickmckinney

Yes those are my cams in that car. Its actually 340RWHP SAE give or take (all the charts I have are 346RWHP STD) However it was already at 330RWHP with PI heads before the ported TFS head swap..........He later went to a lower compression shortblock and with the TFS intake its now at 330RWHP or so.

I have another guy crying his eyes out at 290RWHP on a 5.4 (other shop) ported TFS head motor with Eddy intake and adapter plates on Comp270AH cams. We installed a set of my cams and got it up to 330RWHP. He has spent $8K already, I told him to make any real power it needs a Logan intake but thats beyond his hurting wallet at the moment. There are many many more stories like this one.

These are race heads with massive intake flow and need to be used under conditions that don't choke them down, which unless its a roots style blower means turning some serious RPM. You install a plastic PI intake on TFS heads you might as well run a 300 lift cam. The TFS heads at 300 lift are already outflowing the plastic intake.
