Cool guys, thanks, looks like I'm probably gonna keep the Blazer (my 94 5.7 TBI) unless i decide that I really need 4 doors among a few other things in a newer model. It seems to me I am getting the same milage out of my TBI as most are getting from a Vortec (I get 14, and am gonna work towards getting better)

Thanks for the replies
