I'm trying to find out more of what you have done for modifications to your p/u I can only seem to access the pic's. My 9 y/o is getting tired of helping the old (computer illiterate) man I have a 82 k10 w/ a c6.2. runs good only more blow by then I want to see. I'll be doing a comp. test soon. I picked up a 82 J 6.2 that has a fairly new i/p @ starter. Story goes a head gasket went out a couple weeks after i/p pump. So he pulled out and went gas. I want to know the most cost effective way to go. So I can do it once and do it right. Thank you in advance. Steven
