Performer or performer rpm ?

Ive one of the guys whos never understood why someone would get the performer intake, when you get the rpm that does the same thing only better...

Combo
305 HO (220 hp version, 9,5, 416 heads)
Lunati 60100 cam - initially wrote 60101 sorry !
Intermediate Headers
q-jet and Hei dizzy

Would you get the performer intake or the rpm ?

I`m building this for mpg but hoping to have 230-250 hp too.

If I get the rpm I can use it later on, if I decide to change the block out to a 350 too, on the 305 I guess the performer would be sufficient, but AM I giving up mpg with the rpm version ?

And do you think I will get more hp with the rpm ?
The cam is listed as a 1000-5000rpm basic operating range. (maybe a tad higher on the 305 - but limited by stock valvesprings)

Re: Performer or performer rpm ?

On a 305 I would use the Performer.

Re: Performer or performer rpm ?

third option, Performer EPS. That said I have seen the difference personally between the straight performer and the RPM. My theory is that the RPM, while intended for slightly higher RPM was just a more refined and improved version of the relatively-old Performer. Just like heads and cams, with time and technology things have just gotten better and more flexible. Just a theory.

Re: Performer or performer rpm ?

I voted for Performer but if you go RPM make sure you get the one with dual bolt pattern for both squarebore and spreadbore.

Re: Performer or performer rpm ?

On a 305 the stock one works just fine! Save your money for a bigger engine 1st.


I never make mistakes, but on occasion I present myself with an opportunity to get very creative.

Re: Performer or performer rpm ?

With HEI, or multiple spark ignition, & electric choke, I'd use the Air Gap w/your combo in a New York second


Similarly to your original comment, can't see why any one would want the RPM over the Gap.

Re: Performer or performer rpm ?

I voted performer. I put one on my 350 with HEI, smogger heads, stock manifolds dual exhaust. Made it more responsive, and was cheap too. I think my next addition will be a lunati 60101, too.

Oh man ! I did write 60101, was going back and forth between the 60100 and 60101 and now I got myself confused.

I changed the first post to 60100 so it should be okay now thats the cam I bought, for those who would have voted differently I`m sorry.. !

Re: Performer or performer rpm ?

For a cruiser, street truck or fairly stock engine the performer is the way to go. For moderate performance the RPM is best. I have an RPM square flange and an RPM dual pattern. Not sure which one to use ? Also have a Holley 3310 750cfm and a stage 2 Jet Quadrajet. Both new. Which one to use on my 383?
