Eco-Friendly Nostalgic Muscle...Is it possible?

If I ever build one, that's probably what I'll power it with... pick up a '96 to '98 cobra engine (aluminum block), have it rebuilt, slap a blower on it, and WATCH OUT!

Quite a few guys are running that 4.6 motor down here. Unfortunately it doesn't meet the latest emissions requirements. People are switching to the newer Aussie version which is the 5.4 bottom end with the 32 Valve heads on it. The only problem with them in a Cobra is they are a very wide motor and difficult to squeeze into the engine bay.

With the Hot Rodder spirit that abounds on this site and with our customers, I am pretty sure someone will figure it out--sooner than you might think.

Well it already has been figured out. We're just slipping under the radar running race cars on the street. Detroit is building higher HP engines now than ever existed in the past. Unless someone knows of a 500HP small block that was in a production car in 1969. Plus at that time a "clean" car meant it left a fairly small cloud behind it.

I'm sure many remember how impossible it seemed we'd ever see a V8 family car again. Wanna meet today's standards? OK buy a complete detroit setup. Wanna meet next year's. Uh OK, buy detroit's setup for that year.

This probably isn't the best crowd to ask for emmissions improvement ideas. Personally I'm trying to figure out were I put those remote controlled exhaust dumps I had.
