I have installed a LT4 hotcam with all that other jazz, FLP LTs, ORP, and a lakewood DSL, 2800 stall, 3.42s, and that's really about it.

I have been noticing a real weird vibration that shakes the whole car, and no it's not the cam, I don't really know what it is.

What should I be looking for? I can't really give you any more specifics because the possiblities are just too numerous. Narrowing it down to possible DS problems, stall problems, transmission related, slightly singed O2 wire, anything?

thanks for the help if you can.

 

You'll likely find an improvement with a nice aluminum DS.........and get a bit more power to the rear wheels at the same time.

 

I would venture to say your exhaust system. As soon as I put LT's on and an ORP, I got a nice vibration from about 70-80MPH

 

interesting. thanks guys for your input. i'll look into the exhaust aspect of it and see what I can find.
