Have a 55 Hudson Hornet in the shop right now that has the V8 option which is the 320ci Packard engine. It runs like scat and has the factory ONE BARREL carb. On the GM I6 engines doing anything speed related is a waste of time in my opinion. Now for rock solid dependability, great low end torque, and long range durability they are among the best but not suited to hot rodding. Show me any Chevy/GMC six cylinder of any size or configuration, multi carbs, super/turbo charged, ignition, exhaust, etc and apply the same thing to an engine with seven main bearings and a 12 port head and it will show how much time and money was wasted on the GM engine. All is not lost as after just 65 years GM has given us the 4.2 (or Atlas) I6 which should be able to run with the Aussie equipped Ford I6's. Jerry "Hot Rod Lincoln" is now working on a "Dumb" Atlas engine equipped with carb(s) and conventional ignition to make it a doable bolt in replacement and finally giving a GM six with balls.
