    220 at idle, or 220 going down the road? Could be running lean (checked the plugs?), could be too far advanced on the timing, or not advanced enough. need a little more information on your fuel set up, cam timing, ect. if you are running a carb is your fuel pressure set right? Could be a few different things.

    Are you using aluminum heads? I think that helps.

    Here's a pretty good checklist that I helped put together on another forum...

    I thought my 454 was running a little hot, but a friend of mine said the newer engines were made to run hotter than the classic engines I am more accustomed to.

    The 454 I am running is a TBI engine out of a 1992 Suburban.

    OK---tell us about your radiator and if the water pump and drive pulleys are standard, underdriven/overdriven and also does the pump turn the correct way?(switching serpintine pumps to v belts reverse them
