Sounds a bit like what Jay Leno had done to the big engine in his "Blastolene Special". The Continental AV1790-5B M47 Patton tank engine originally produced around 800 horsepower and in the car got around 2~3 MPG. After Leno had the Greyhound bus transmission replaced with a six speed Allison automatic (used in semi tractors), installed fuel injection and twin turbochargers, it doubled the horsepower to 1600 and gained 100% MPG increase to 5 MPG. http://uncommonengineering.com/ Crazy things done to flathead Ford and Hudson straight 6 engines by a person who used to build engines for Indy cars. Imagine a 308 Hudson with added webs in the block for a custom 7 bearing crankshaft, EFI and a 6-71 supercharger. ;-) He's also revived the ARDUN overhead valve heads for Ford flathead V8s and that totally insane flathead intake that mounts TWO superchargers. Probably best to use that on the somewhat stronger Mercury version of the flatty. Then there's his custom heads and camshaft that changes the in block intake valves to exhausts (for 16 exhaust valves) and has one huge, centrally located intake valve per cylinder. It takes no imagination at all to assume that nothing this guy builds is in any way inexpensive. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
