Hi all,

I bought a built up 454 mark iv engine to install into my 67 impala. I would like to install a different intake and cam before I put it in the car.

The intake is an Edelbrock Torker II which is Rated by Edelbrock for 2500-6500 RPM. I would like an intake that is designed to produce power and torque starting a bit lower than 2500 RPM.

i want to change the cam because I have heard this engine run and it idles too smooth. Yes i know, I should not chose a cam by what it sounds at at idle.... But I do want one that produces good power and torque as well as idles a bit rough.

Ok so heres the rest of the story.
Car is a 67 Impala sport sedan
Transmission is a Muncie M20
Rear end is 12 bolt, 4.10 and positraction
Tires will probably be 28" tall

289 block
781 heads
Compression ratio will be 9.5:1
It has roller rockers.
Headers with 2" primaries and 3.5 outlet
Carb is a Holley 750 double pumper

What intake and cam should I use ?

I was looking at the Edelbrock "performer RPM" intake

I was looking at the comp cams thumper or mutha thumper cams but am unsure of what is best for my application
