Check cam manufacturers for a street cam that is a computer friendly. You can look at the ht383e drop in for the specs on the newer cam GM put in it.

 

[kingjer]

That 383 is a gm crate motor right

You'll need a tune with any cam swap I bet ... should get one even without a cam.

Kingjer If you have US built 1996 your are ob2 and some options would a straight questionnaire-based blackbear tune or a 0411pcm swap and a scan-based tune.

I have Canadian built truck....yeah sorry was thinking of my other yukon its 94

 

[SunlitComet]

Then look into the above options to play with.

I just putt in the closest cam I could find for my yukon 5.7 vin r I I still needed a computer reprogramming.... for me even that small of a difference made for some fuel adjustment and advance....

The "Tune" will net you as much or more performance than the cam swap. No matter which cam you choose you wont tap the full potential of the cam until you have the computer programmed to take advantage of it. By planing on the tune at the same time as the swap you can look at cams that fit the profile of what you want to get out of the truck vs what will "work" with a very de-tuned stock computer.
