I understand what you are sating DD,and for my tastes I agree. But for a mild, reliable, economical, daily driver...the performer stuff will be an all-around improvement over a stock c-code build.

EXCEPTING the intake Only difference there is the 10-20 lb weight savings.

Are you stalking me D? LOL

The C-code was a 2v, so yes the plain old performer (aluminum 4V) WILL give improved performance over the cast iron 2V, perhaps not an economy improvement but that depends more on the weight of the right foot than anything else.

Last time I checked a 300hp flywheel motor ran pretty good, and thats what he, theoretically, will get according to edelbrock with the performer package.

300 horses at the flywheel would be plenty for me! thats enough to not be afraid of most cars here in lexington.

I would like to take this space to side with the guys in support of the RPM intake. Ive got a few years of magazine artical and diffrent forum reading "experience" under my belt and have heard nothing but good from the RPM intake. nearly ALL say it beats the performer in almost every aspect and its downfalls are SO minute, they probly should not be mentioned at all. I plan to bolt one on top of my first build-up according to my research.

Do what you want to do.

Agreed, the milage "might" be improved over a stock 2 bbl intake, but like you say, that depends on the right foot. Otherwise the Performer is simply a lighter weight stock type intake. For that, I'd just pick up an 80's 5.0 4 bbl stock intake on ebay for $50.

well, since you have the performer, get the RPM, try it out, and if you dont like it.. sell it to tyler

BTW, if you dont have one already, get a trans cooler too. External from the radiator.. more HP will equal more heat in the trans

So, if the RPM is so good, why did it slow my vert down?

I threw an RPM on my Mustang years ago in place of a 2v set up, using stock cam and manifolds. The car was softer off the line with the RPM than with the 2v.

That changed when I swapped 3.50 gears in place of the 2.80s.

Still, the gains up top would still make me choose the RPM.

Yes just go with the RPM and be done with it. Performer is a waste of time. The RPM does not compromise streetability.

A more detailed list of what your 'vert had under the hood is in order for that question to be answered. Just from what you listed in your signature, a few questions come to mind. 1. What cam did it have ? 2. How much tuning did you do to that 600 Holley ? Or was that the carb you had on the RPM ? The improvement could be due simply to the carb. For instance, if you ran it as is out of the box with that combo, the secondaries may not have been opening, or opening too soon and that, combined with an insufficient accellerator pump shot would cause it to bog off the line ( too lean with the larger plenum volume) I can think of a dozen scenarios

It didnt bog at all, just lazy. RPM's didnt climb nearly as quick. With the AFR's, you'd think the RPM would have given me more top end, but it didnt happen. Engine has the stock hyd roller with 1.7 rockers, so around .470 lift at the valve, BBK shorties, the performer with a port match, 80457s holley with jet conversion, 65/73 jets IIRC, 1/2in 4 hole phenolic spacer and the factory EGR plate and AFR 165 heads. And yes, it pulls right up to and peaks at 6k rpm with the HP. You'd THINK that with the higher flowing RPM intake, that I'd pick up on the top end at least...

Sounds like the secondaries weren't opening, or not fully anyway. Did you play with different secondary springs ?

One question, how much HP and tourqe will a 351w get with the performer plus package (intake, 600cfm carb and cam) + hooker headers and 2.5" dual exhaust?
