I have a 454 engine in the machine shop getting bored and stroked out to 489.

The engine is getting aluminum heads, intake manifold and headers saving a little over 100lb.
The compression is getting bumped up from turn of the (19th) century 7.9:1 compression to 1960s muscle car era 11:1.
Conversion from 1950 style flat tappet to roller everything valve train riding on a slightly advanced 270 grind cam. Advancing the cam timing will improve fuel economy, low end response and torque at the cost of high end horse power on an engine that could produce 500hp and 600 torque easily I can give up some on the highend.

To help save fuel I developed a switchable cold air to warm air intake I mostly developed before I pulled the old 454. Warm air at a controlled 90F when going down the highway and in town, cold air for when I open it up. No reason to run cold air all the time.
Lean burn, I tuned the current edelbrock 650 for lean burn. Which almost doubled fuel milage from the stock configuration. For the new engine I want to run an edelbrock 800, it should have a 1000 or even a 1200cfm but the 800cfm will give better results all around on the low end.
To encourage some EGR, with out an EGR I am going to run restrictive stock style exhaust system aided by cutouts when I open it up. No reason to run a wide open exhaust system all the time.
To prevent preignition I was going to use water methanol injection. I have already developed a pretty good water injection setup for my diesel.
This engine is going into my suburban now, but I am sure it will find its way into my Camaro in the next year or 2 depending on how often I go to Afghanistan.
This isn't what I want to do this is what I already bought parts for and is waiting at my friendly neighborhood machine shop for me when I return home. Some assembly will be required by me, which is pretty much everything the machine shop only did the machine work and bought most of the parts at their special dealer rates.
