This is always the case. :) But it is a lot of fun.

It sounds like I am trying to Hot Rod an engine, actually I want to improve the efficiency/fuel economy of a Packard. My first thoughts were a longer stroke engine would produce more torque allowing the car to accelerate more easily and not need to be revved as much, which uses proportionately more fuel and a long stroke engine can't do anyway.

I am thinking I would use a 356 engine at this point.

I was going to use computerized engine management: port fuel injection and distributor-less ignition to get more power from the same amount of fuel.

All flat heads have poor breathing characteristics. My thought is to add low boost (5 psi or less) to counteract this and increase torque as well. I would use 2 twin scroll turbos, the smallest possible that won't choke at redline even if not much extra hp is created there. Looking for the earliest onset of boost and an increase in torque. Intercooling would increase efficiency, too.

Use a ZF 8 speed automatic transmission to further improve fuel economy.

But I want to keep the car looking stock.
