FRPP Hot Rod Cams Initial Thoughts

So I installed a set of FRPP Hot Rod Cams this weekend and have to say I love the old school muscle car lope and deeper note the ole girl has now. I also took the time this go round to clean, prime & paint the valve covers Ford blue while I had them off again. I believe the tune is running a bit on the rich side, but I 'll have to do some data logging and checking plugs to verify. One unexpected side effect is that the change idle smoothness has revealed that my original throw out bearing is probably shot (190k miles on original equipment no surprise) as it rattles/clunks when not engaged in neutral. It goes away immediately when the pedal pressed in. I don't hear it when I get the rpms up above idle (750~800rpm). So I guess I'll be doing the clutch assembly next.

Looks great. It prolly just smells rich to you due to the dual overlap on the exhaust ports from the cams...that's how they get their sound

So headers are right around the corner then? Lol.
Btw, valve covers look good.

Yep. Bought a set of open box Pacesetter and matching H-pipe. One of the headers has a dented collector flange that I'll have to get put back in round then I plan on stripping the black protective paint, priming and repainting with VHT High Temp Ceramic rattle can paint. They have a grey that closely matches the tungsten grey of the body. Plan to do the install in early July. Probably do the clutch assembly and rear main seal(preventative while the tranny is out).

Do have to say its taking some relearning how to time the clutch & gas to take off without nearly stalling. Haven't yet though!

I was thinking that may be why too. Just have to get used to the way she runs now.

Those were my thoughts as well right after I put mine in...even to this day she still smells rich but a/f is spot on...hope you like them...be ready to talk about them at about every gas station you stop at as everybody seems to like the sound of these.....not really a bad thing though

For those who are using these cams, what is your hot idle rpm? Its currently set to 740 neutral. At times it feels like its about die especially when the AC is turned on and I even have UDP installed. Thinking it should be bumped up a little to 840.

Mine is at 740 as well...but its an auto. When I was using an e-mail tune my car would run the same as yours...wanting to die.. idle would dip.. car would buck slightly at low speed and low rpms...but after I had it dyno tuned all that nonsense went away. Up it to 840 and see what happens...it should help.. the lobes of the cam might lose some choppiness though...

I know I have different cams but mine looks to be around 780 and it likes it. 840 seems a little high to me.
And like Andrew said, dyno tune smoothed everything out.
Mine DID idle fine when I was running a dataloged tune but I also had cam bucking in low rpm situations pretty much daily.
