i know the specs on the stock cam in my 91 LO3. im not a perfessional when it comes to camshafts.....what should be the specs for a new cam? i only have a 14X3 OE and a custom exhaust setup that includes no muffler and a resonated tip...... any help would be greatly appreciated

 

even though your engine is mostly stock i would say to put in a lt1 cam and well as lt springs and you will definitly feal the difference

where would i go about finding this famed LT1 cam? how much would it cost? does anyone know what the specs on it are?

 

I depends what year and what bodystyle. The impala had less duration than F-body and Vettes. But go to Scoggin Dickey or Jim pace and one of them will have it. It is a good cam though, the impala one will give a little more down low but not as much top end. I would get a F-body or Vette one. But go to those sites and I know one of them has some factory cams. You may want the LT4 cam, go look.

I bought a used one cheap from the for sale board at http:// camaroz28.com .You see them all the time for $30-$50.Its working fine even with the stock chip.

would a higer duration number give me a more "rumpity" idle? or is it the other end around? i would like to gain power across te rpm range..most down low but i do want to be bale to rev past 4 grand without it being all bark and no bite.....

 

The lobe separation is mainly what causes the rougher idle and the computer doesn't like that. Don't try and run anything with less than 112* lobe separation. I run a Compucam 2050 in my truck which has the 112 degrees. It has a mild lope and causes the computer to try and compensate with the idle. So my idle can be anywhere from 600 to 1200. But it does run well besides that. If you drop below the 112 your car may stall on the dips.

thats exactly what i want, er what i mean by rumpity....just generally something to scare the **** out of ricers cause my car is shaking back and forth from the idle i love that.......my da had a souped up 68 stang the had the wildest cam form crane that was still street legal and the thing was a beast......he said i always had a smile on my face in that car and i still crack a smile everytime my car gets warmed up and its sitting at 600 rpm idling and shaking back and forth a little bit....plus its for the ladies too

 

I can get my camaro so shake like that, but I fixed that vacuum leak.
