I am looking to rebuild my 350 TPI engine on my 87 IROC. The shop is suggesting a crane cam #2050. I am not looking to make huge amounts of power, this is my daily driver. I also live at 6500ft and need to pass emissions. I am thinking the 2032 would be a better option. Can someone give me some help on deciding what lift/duration/seperation to use for a fairly mild street car?

 

The cam part number 104224 in a 350 stock engine from your year picked up 18 HP. This is a crane compucam and adding 1.6 rockers will maybe give you about an extra 10hp.
Specs:
Lift (1.5 rockers)----452/465
Lift (1.6 rockers)----482/496
Dur @ 50--------------214/220
LSA----------------------------112

Hope it helps
