The X-pipe or a crossover will help your low-end torque a little bit, and usually gives the exhaust note a unique sound.
I'm curious why you want the choppy idle. Do you want performance, or are you just interested in trying to impress your friends with the sound? True hot rodders won't be impressed.
Thanks Henry Rifle a decent reponse, ive had some friendly thread hijackers.Quote:

What cam would you recomend for my engine.
Hey, now wait just a minute!!!! I had that position at least a year before either of you showed up!!!!!!:LOL: :LOL: :LOL: :LOL: :LOL: I should at least get to decide who my replacement is......
Scoggin Dickey uses that cam in their ZZ465, along with 1.6 rockers. However, you would have to upgrade from the stock springs on the FB385 heads to handle the higher, more aggressive lift. Should give more HP and the lopey idle you want, but it's pretty radical for the street. Power band is going to move more toward the high end at the sacrifice of low end torque. That may not be what you want on the street.Quote:

The gearing, weight, camshaft, compression ratio, head flow, carburetor and ignition system have to be designed to work together. Put too much cam in that car, and it will eat gas, and won't have the grunt on the low end on the street where you need it.
What car are you putting it in? What carb are you using? An engine that starts pulling at 3000-3500 RPM in a heavy street car is not fun.

Junior, if you are serious about getting the best cam for what you have, give Cam Motion a call. They will make YOU a cam that is matched to every component on YOUR car. Part numbered cams are o.k. but a custom cam built around what you have and what you want is unbeatable. It takes all the guess work out of matching components and what will work and what won't.
A cam can give you a more raspy sound and more h.p. but you might want to look at mufflers for sound, as in the Super 40 series. Mufflers add a lot to the sound quality but another factor is compression. Compression will add volumes to the quality of the sound as well as h.p.Quote:

Well I guess he would say darn near anything.:LOL:
If you look at cams that have a narrow l/s they will tend to have a rougher idle than a cam that is ground on a wider l/s.Quote:

Im not sure what your telling me on the cam. I also dont want a really rough
idle that will bust my ear drums,and knock my teeth out. I quess i justy want a little lope sound. I just might go with the hot cam kit its all been figured out to just slap in with a 425hp dont know if it will gain torque or drop torque. The motor already produces 385lb of torque at bottom end, whith
this hot cam dont know where it will put me at..
With the Hot Cam and 1.6 roller rockers, the FB 385 becomes a clone of the ZZ430, which is supposed to make 430 HP / 430 lbs-ft.
Henry i see you too have a 385 fast burn but with more hp. what hp are you at and what cam did you use ? I was reading on the post of the vacum advance deal being to high. I myself had that problem when timing me engine,
but now i know why.
