I have a low mile 96 vortec 305 in my 4wd ext cab Silverado, and would like to put it in my 95 ext cab 2wd dime that has a what I believe to be a TBI 4.3? Would I need a 411 box and do the nessasary "pin-out" (hope I'm using the right termanology?)or would I use the existing 95 dime harness?ID like to keep it fuel injected,and run the 305 with a wct5 I have from a 90 camaro?I'm NOT looking to run any emissions crap,egr,or AC/heat,and will be shaving the firewall.PLEASE help!!!,as I don't want to carb this engine!!!
