You should really do the headers, catback exaust, free-flow cats, and cold-air intake first. It made a huge difference to my 4200lbs car. I had 260hp/330 lb/ft (crank) from the factory. I have maybe 300hp / 350 lb/ft torque (crank) now with the stock iron heads and even in normal relaxed driving it is noticeable. If you really want to do the cams now, try this link. It is the GM Performance LT4 'Hot Cam' kit and was designed by GM for the LT1 as a direct replacement. Summit is company I use alot. They have a great tech info also. Just call and ask.

Here is link to the cam and lifter kits. There is a selector for street, street/strip, and strip also to help you decide.

Here is alittle extra also.

And for big future mods a stroker kit can give an LT1 383cu-in about 500hp / 500 lb/ft torque (crank) and still be really good daily driver. Hope this answers all your questions.

Sorry this is off your topic but...
Hey Gregg-O, are the cats in my Impala ok for the parts that I have, are they the same as the LT1 Camaro or lower flow-rate ? I have to have mine changed and am not sure if stock replacements will do.
